The machine for production of profiles for gypsum cardboard. Profile production for drywall: materials, types and brands of manufacturing equipment. Types of manufacturing defects and their symptoms

  • 17.04.2020

GKL, that is, gypsum plasterboard, today is one of the most common finishing materials used in the renovation of apartments, offices and other premises. Lightweight, durable, inexpensive, reliable and at the same time easy to use, it is found almost everywhere today.

Therefore, it is not surprising that the production of drywall profiles eventually became a fairly common business model. After all, the profit received from its implementation quite confidently covers all costs.

Let's take a closer look at this investment option, analyze all its strengths and weak sides and let's talk about what you need for those who want to try their hand at this direction.

How to equip production

The first thing you will need is a production shop in which you will install a drywall profile making machine. The premises should be spacious and clean, located close to transport routes, and it will also be necessary to place a warehouse for finished products and a packaging workshop nearby.

The use of drywall is growing, which means that the demand for related materials is increasing. At proper organization business for the production of profiles, the profit will cover all expenses and generate income.

First of all, it is necessary to determine the form of ownership and register the enterprise, and then select a room that fully meets all the specified parameters, after conducting preparatory work you can start choosing raw materials and machines.

Raw material

Equipment such as a drywall profile machine uses steel strip or finished galvanized steel sheets with a thickness of 0.3 to 0.7 mm. The thicker the steel, the more durable the structure will be in the end, but the cost of production will increase accordingly.

You need to purchase raw materials only from trusted suppliers who have all the necessary licenses and quality certificates. Remember that acquiring questionable material will lead to questionable results. Also, don't forget that all business relationship must be supported by accounting contracts, and payment is made strictly according to invoices in a non-cash manner.

This approach will protect you from unscrupulous and dishonest businessmen who are in constant search of green newcomers who can be “thrown” for money.

A little more about raw materials: it is important to choose a supplier that is located near you or provides free delivery of its products to the consumer. This will reduce costs and increase profit margins. It will be important to indicate the volume of supplies and penalties in case of non-fulfillment, this, in turn, will secure your obligations to your customers.

Equipment and personnel

When choosing a machine for a drywall profile, remember that there are several main types of profiles that make up frame structures. Some of them are in constant demand, and some are of little demand. Choose the right machines for a quick start.

The drywall profile manufacturer must first of all start from the market situation in order not to incur losses as a result of poor sales of his product. The profile is listed in descending order of its demand on the market:

  • carrier profile. It is divided into wall and ceiling. From this type of profile, most of all frames used when working with gypsum boards are made. There are several basic sizes that are in constant demand.
  • ceiling profile. Almost completely repeats the wall elements, but has a notch and a large width of the lower part.
  • Guide profile. Without it, it is absolutely impossible to carry out the installation of the supporting profile, but the volume of its purchases is much lower, since this profile is used only for fixing structures to the base surfaces.
  • Perforated corner. Serves for reinforcing external corners at the stage of rough finishing.
  • Beacon profiles are also in demand, but, strictly speaking, they do not belong to profiles for working with gypsum boards and are used for plastering.

You can take a drywall profile machine that produces both types of these profiles at once, the so-called double-thread machine. It can and should be supplemented with a special guillotine, which will cut off the profile of the required length, this will allow to produce more products.

For the packaging shop, it will be necessary to purchase cardboard sheets to cover the ends of the profile, ties to attach them to pallets and all the necessary equipment.

Keep in mind that the profile takes up a lot of space, so you will need a forklift and cargo racks for the warehouse, which allow you to place the production products as ergonomically as possible.

To sell a profile, it is necessary to check the manufactured product and prepare all certificates for it.

Take Special attention transportation, packaging and storage of products.

It is also necessary to obtain a certificate confirming its quality. To do this, it will be necessary to give a sample of production for an independent examination and pay all necessary fees.

The average productivity of machines is 10 - 20 linear meters per minute. To increase performance, the following conditions must be met:

  • Filling machines with tape rather than cut strips of metal will reduce the number of operations, work time and increase productivity. But this also requires:
  • Equip the machines with a pneumatic cutter to separate the finished product; to control its operation, you will need a CNC system (computer numerical control).
  • To ensure efficient operation, two employees per line will be required.

An increase in productivity leads to an increase in turnover, but an increase in staff leads to an increase in the cost of its maintenance, which means that such optimization only makes sense if you have a regular consumer of your products and you need to fulfill the production plan.

Sales

The best business model would be to find your customer and enter into a purchase contract with him a certain amount products before the start of production. In this case, all risks and costs can be calculated, as well as implementation problems can be solved before the start of the production cycle.

When selling a profile, it is better to focus on selling goods in bulk.

Ideal candidates for this would be large construction companies, the demand for a profile in which remains stable regardless of external circumstances. If you can ensure the required quality and volume in the long term, we can say that all the tasks set for the business have been solved.

Otherwise, you will have to organize a sales department, a logistics department, as well as expand storage space and ensure the efficiency of this entire system. Therefore, the best solution would still be to first find ways to implement and only after that proceed with the purchase of equipment, recruitment and other operations to implement this plan.

Start with detailed business plan and search for potential large consumers, and then your business is guaranteed to bring you income.

The machine for the KNAUF profile of the GK series is designed for the manufacture of galvanized metal profiles used in the construction of plasterboard structures. As a blank, either a strip of a certain width or strips of the same width and the required length are used. It produces standardized profiles - PP 60x27 and PPN 28x27, the width of the workpiece is 123 mm and 81 mm, respectively.

The drywall profile production line consists of a roll forming module, a stationary (stationary cut) or a flying (flying cut) pneumatic guillotine for transverse cutting of the product after the profiling process, an automatic control system (ACS). Optionally, the operator's touch panel for the automated control system greatly simplifies the process of entering and controlling parameters, and also allows you to enter up to 10 different production programs (length and number of profiles) into the machine's memory. Additionally, a device for applying notches to the profile PP 60x27, as well as a device for punching holes on the profile PPN 28x27 can be installed on the profile machine.

When rolling profiles from strips of the required width and length, there is no need for a guillotine and automated control systems, which reduces the cost of equipment for the production of drywall profiles, while productivity also decreases. One person is needed when handling the roll. The operator fills the strip, sets the operating mode to the control system (length, number of products and speed). The “flying” cut device allows increasing the productivity of an automatic profile production line by 25-30% compared to a stationary cut and by 50% compared to a machine without a control system, thereby reducing the cost of the products obtained, making the production of a drywall profile a very promising direction.

We can also make a machine for the production of profiles for drywall under the order, for any type of Knauf-type profile. A complete catalog of equipment for the profile can be viewed at the link

Machine modifications for drywall profile:
  • rack profile PS 50x50, guide profile PN 50x40;
  • rack-mount profile PS 75x50, guide profile PN 75x40;
  • rack-mount profile PS 100x50, guide profile PN 100x40.

Given the high demand for building and decorative structures based on, those components that are used for its installation are also in demand on the building materials market. And here you can include a metal profile. The conclusion suggests itself - if you buy a machine for the manufacture of drywall profiles, work out the range and technology, you can start earning right today. It has already been proven in practice that the profitability of production is quite high. Mounting profile for drywall - a metal product made for ease of installation of the material in different versions. It is actively used in the construction of buildings and their decoration.

Our business valuation:

Starting investments - from 600,000 rubles.

Market saturation is average.

The complexity of starting a business is 5/10.

In order not to require large investments to launch the enterprise, it is better to immediately abandon the organization of a large-scale plant. For start-up entrepreneurs the best option will open a mini plant for the production of drywall profiles. What are the stages to be passed on the way to success and big profits?

What assortment to offer consumers?

It would seem that there is nothing complicated and unusual in such a simple product as a mounting profile. But for certain purposes, builders may need the most different sizes and profile types for drywall. And in order to earn the trust of customers, it is important to provide them with a wide range of products that differ in application and geometry.

It is worth considering the assortment even before purchasing all the necessary equipment, since many machines can only produce one type of profile. But for the production of a whole range of products, multifunctional equipment will be required. This costs much more.

There are the following types of profiles for fixing drywall:

  • guide,
  • ceiling,
  • rack,
  • beacon,
  • angular.

Of all options ceiling and guide profiles are in greater demand on the market. They are widely used for the construction of partitions, suspended ceilings, and wall insulation. The standard dimensions of the ceiling profile are 60*27 mm. The standard dimensions of the guide profile are 27*28.

The development of the assortment is only the first stage, from which the business plan for the production of a drywall profile begins. There is still a lot of work ahead on the selection of raw materials and equipment.

How is the process of manufacturing fastening profiles carried out?

The production of a galvanized profile is impossible without the appropriate raw materials. And here, as a rule, galvanized steel of the 2nd class is used, supplied to enterprises in the form of strips - strips. And if the standard sheet thickness should be 0.3-0.6 mm, then the required width of the tape will depend on the type and purpose of the product planned for release.

For the manufacture of the ceiling profile, strips with a width of 123 mm are taken. And the guide fastener requires a steel tape 81 mm wide.

To make the drywall profile production business more profitable and less costly, metal raw materials should be purchased from those suppliers that are geographically located closer to production. In addition, the price of the material will decrease significantly if you buy everything you need at once in small wholesale lots.

As for the technology for the production of mounting profiles, it is extremely simple - everyone can master the process. The steps are:

  • Loading the steel coil into the machine.
  • Forming a profile from a metal billet.
  • Packaging and storage of finished products.

It turns out that manual labor is minimized in the production process. And that's another plus. this direction, since the cost of production is reduced due to the refusal to hire highly qualified personnel. The workshop will require the presence of personnel only working specialties.

And since all processes are carried out by an automated line for the production of drywall profiles, we pay special attention to the next stage of business planning - the technical equipment of the workshop.

What equipment to equip the workshop?

In order to buy equipment for the production of drywall profiles, there should be no problems - suppliers offer a lot of equipment options for sale, because this area is characterized by high demand for finished products.

Equipping the workshop, you should analyze the following factors- its cost, power, equipment, functionality. If you study the market, you can choose the option of technical equipment that is suitable in terms of price / quality ratio.

The "medium" line for the production of drywall profiles is equipped with the following machines and devices:

  • Uncoiler.
  • Profile bending machine.
  • Cutting machine.
  • Reception table.

We have indicated a list of the main machines necessary to obtain high-quality products. But to facilitate and speed up the process, some additional equipment will also be required - a beam crane, a loader.

The final price of equipment varies in a wide range - 500,000-2,000,000 rubles. It is important to understand that with the help of cheaper semi-automatic devices, the entrepreneur will be able to receive only 1-2 types of profile. But the higher price of a machine for the production of a drywall profile will indicate that such equipment will allow the production of a much wider assortment, which, of course, will also affect the final sales profit.

Even if there is no minimum amount to equip the workshop, it is worth buying a used machine. And then the cost of purchasing equipment can be reduced up to 250,000 rubles.

Domestically produced lines cost somewhat less than those made abroad. But as practice shows, such equipment is much better in terms of quality, durability, and functionality.

Features of the market for finished products

Since the demand for products is only increasing, consumers can be found without problems. There are several ways for an entrepreneur to develop:

  • Construction companies and contractors.
  • Private buyers.

It's great if the metal profile for drywall is sold in bulk. This will save the entrepreneur from the headache of attracting interested customers. But even so, it is hardly worth "writing off" small private traders. If it is possible to organize a small warehouse-pavilion on the basis of the workshop, where the manufactured products will be presented for sale, this should certainly be used. Then, everyone will be able to come here for the necessary material.

Concerning marketing development opening enterprise, then it is unlikely that it will be necessary to deploy large-scale advertising campaigns. Subject to cooperation with wholesalers, it is much more important to have a profitable commercial offer. And speaking of your own point of sale, advertising still have to invest some money.

And what will happen to the enterprise in the autumn-winter period, when the entire construction market “sags”? Yes, at this time, not many people need a frame made of drywall profiles, but with well-established distribution channels, even in winter, equipment downtime can be avoided. Sales will drop significantly, but this, of course, will not lead to the ruin of the enterprise.

Let's talk about the financial side of things

It has already been proven in practice that even a small enterprise for the production of profiles can bring its owner a high income. But before moving on to specific profitability metrics, it is important to evaluate the capital investment that will be required to start a business.

The production of drywall profiles will require the following investments (including new equipment):

  • Registration of an enterprise - from 10,000 rubles.
  • Purchase and commissioning of the line (without additional equipment) - from 600,000 rubles.
  • Preparation for the work of the premises - from 100,000 rubles.
  • Providing a raw material base - from 200,000 rubles.

In the case of the purchase of supported equipment, capital expenditures will decrease up to 600,000 rubles.

If we talk about a low-capacity workshop (200 linear meters per hour), then with an 8-hour shift 22 days a month, it is possible to produce up to 35,500 linear meters of products monthly. As for the cost of the finished material, much depends on its type. For approximate calculations, let's take the average wholesale price of the profile - 30 rubles per linear meter. By selling the entire volume of output, you can have revenue in the amount of ≈1,000,000 rubles. Part of it will go to the further organization of production, and about 100,000 rubles. the entrepreneur will earn.

Production of a drywall profile - a simple recipe profitable business

This article is addressed to those readers who are interested in the idea own business. By purchasing a machine for making a drywall profile, and having mastered the technology, you can earn decent money. After all, the demand for building structures made of plasterboard is characterized by stable growth, and the price of components will be high for a long time to come.

Selection of production materials and manufacturing technology

Let's leave financial issues aside and talk about the technical component of the business idea. Components of success - high quality products, which is achieved:

  1. The use of high quality raw materials;
  2. High tech equipment.

The metal mounting profile is made by cold rolling from galvanized steel. The production material is strip of low-carbon unalloyed steel with a thickness of up to 0.5 mm. To protect the product, a galvanized layer up to 1.6 microns thick is used.

Galvanized steel is stainless until the protective layer remains intact. If the zinc coating layer is damaged, corrosion centers appear.

Instructions for working with mounting metal structures from manufacturers such as Lafarge and Knauf do not allow cutting the profile with a grinder. Restrictions on the use of cutting disk tools are due to the weakening of the protective properties of galvanizing as a result of an increase in the temperature of the metal.

The technology of industrial production of a metal profile consists of the following steps:

  • The steel strip wound into a roll is placed in the decoiler;
  • The tape in the unwinder is unwound and fed into the rolling mill;

  • The tape is perforated - a relief is carved on it for the convenience of screwing in mounting screws;

  • The perforated tape is deformed by metal rollers, which bend the workpiece at the required angle;
  • At the same stage, if it is provided for by the type of profile, a corrugation is formed on the surface of the workpiece;

  • At the exit from the rolling mill, the workpiece is cut with electromechanical shears, so that the end face is perpendicular to the longitudinal edge;

  • At the final stage, the finished products are sent to the receiver, from where they are transported to the warehouse.

How are rolling machines for the production of metal profiles

Standard production equipment includes items such as:

  • Cantilever coil unwinder - unwinds the metal strip and feeds it to the rolling mill;

Contemporary industrial equipment it is completed with a braking system that prevents the coil from unwinding when it is fed into the rolling mill under the action of inertia.

  • Hole punching unit (optional) - used for punching holes on the profile;
  • Rolling mill - profiles and forms the workpiece, giving it the necessary cross-sectional configuration;
  • Electromechanical shears - a cutting device that cuts the profile into fragments of the required length without the need to stop the work of the mill;
  • Receiving node - a device in which finished products are accumulated before subsequent packaging and shipment to the warehouse;

  • Control system (automatic or semi-automatic) - a device that provides control over the operation of production equipment.

The range of profiles on the market

This table lists those modifications of the metal profile that can be made on specialized machines.

The difference in sizes, and, consequently, the configuration metal products explained by the conditions of installation and subsequent operation.

Rack profiles have large transverse dimensions, in comparison with the guide counterparts. This difference is due to the fact that the guide products are used in the installation of suspended ceilings, and in this case, the assembled metal structures should be lightweight.

Rack products are installed on walls, and therefore there are no serious requirements for their weight, while the width is made larger for better contact of the plate with the mounting surface. The length of the products listed in the table also varies. This is because the length of the ceiling rails corresponds to the length of the ceiling, and the length of the racks corresponds to the standard height of living spaces.

Taking into account the large length of the profiles with small cross-sectional dimensions on the side, corrugations are made during production. The corrugation performs the function of stiffening ribs, preventing the product from bending in the middle.

When assembling the supporting frame, in addition to the profile, you will need hangers, connectors and extension cords. These structural elements are also made of metal. They allow you to fix the rails on the mounting surface and securely connect them to each other.

Types of manufacturing defects and their symptoms

  1. Insufficient metal thickness.

This is a common drawback of products from artisanal manufacturers who save on the purchase of metal of the required thickness. As a result, when fixing the sheathing plates, the self-tapping screw is not fixed, but the cut thread is scrolled and broken. In addition, the strength of the supporting frame suffers, which negatively affects the reliability of the finish.

  1. Multiple areas of corrosion.

Rust in several places on the surface of the profile indicates the poor quality of the galvanized metal. It is not worth buying such products, since it will not be possible to stop the corrosion process, and this threatens to destroy the assembled metal structures.

  1. Poor quality profile.

A symptom of this defect is a broken profile shape. That is, the longitudinal edges of the shelves can be pressed through or twisted. It is not recommended to buy such rolled metal, since it will not be possible to set the carrier according to the level.

Similar symptoms are typical for rolled metal, which was stored incorrectly in a warehouse and which was deformed in piles.

  1. Non-compliance with standard sizes.

This is the most unacceptable type of marriage, since it is not easy to work with such products during assembly, and it will also be difficult to sheathe the frame. Previously, the table indicated the dimensions for different types of profile. The difference with the listed cross-sectional dimensions must not exceed 1 mm.

  1. Insufficiently intensive application of the notch.

This defect is inherent in the products of small enterprises, where, in order to reduce labor costs, the outer sides of the product are made almost smooth. As a result, when installing drywall, self-tapping screws are poorly screwed into the metal, since, due to the lack of perforation, they have nothing to catch on.

  1. The edges of the profile are burrs.

I do not advise anyone to buy such products, since you will have to additionally process the edges or come to terms with the risk of injury when doing installation work with your own hands.

Conclusion

From the article, you learned how the workflow is organized, where the main thing is a high-tech machine for a drywall profile and high-quality raw materials. Additional information on the topic can be gleaned from the video in this article. If you have any questions, then ask them in the comments.

To date, drywall is very popular among the finishing materials. It is not only used for arranging interior partitions, but also for creating multi-level ceilings and walls. Moreover, the simplicity of its installation allows even an inexperienced builder to cope with it, which is one of the reasons for its frequent use by ordinary people for their needs, without hiring craftsmen for this.

Product Features

For execution finishing works that use drywall can be used different types profile:

  • ceiling;
  • rack;
  • guide;
  • angular.

Most often, the first two options are used, because it is from them that a frame can be made for further mounting sheets. For their manufacture, galvanized steel is used in the form of a sheet, which should not be lower than the second cash desk. Such sheets are bought in the form of ribbons rolled into large rolls, which are also called strips.

Necessary equipment

The whole process of producing a profile for drywall is to work on a small machine for bending steel coils. It includes the following components:

  • pneumatic guillotine, which cuts the sheet across after the profile is formed;
  • sheet bending module;
  • control system;
  • it is possible to install an operator panel that allows you to quickly enter and save a large number of parameters and control for the manufacture of the profile.

You can refuse to buy and use a guillotine, and even a control panel, if you find sheets of an already cut version to the required dimensions of the workpiece. In this case, this will save not only unnecessary equipment costs, but also reduce the number of procedures performed near the machine during the manufacture of the product.

In the case of using steel in coils, you will have to keep at least two workers so that they can monitor the correct operation of the system. They will thread the strip from the roll, specify all the necessary parameters in the control module and monitor the operation of the machine, while adjusting various parameters.

We also note that if a flying cut is used, this allows to speed up the production process by almost 30%, and the cost of finished products is slightly reduced.

Profile production

To create a high-quality profile, you need a sheet with a thickness of 0.3 mm to 0.6 mm. Moreover, the sheet must be galvanized.

If we consider specialized literature, then we can distinguish three main stages of production from the instructions:

  1. The process of configuring all hardware parameters is in progress. Even the thickness of the sheet is indicated.
  2. Loading sheets or ribbon is in progress.
  3. There is a process of bending the sheets into a profile.
  4. Profiles are cut into finished products using the specified length parameters.

As you can see, all this can be achieved very simply if you have an automatic production line at your disposal. In this case, the process will be very fast.

We also note that the business plan for the production of a profile for drywall should contain one selected direction out of two possible:

  1. You will not have a large assortment, because you will put the machine on the production of only one type of product. This will give you better performance.
  2. You will have to spend a lot more money to make a line for the production of several types of profiles at once. At the same time, you do not need to expect great performance. But due to the fact that the range of products will increase, it will be much easier for you on the market. Even with a doubling of the amount of investment in equipment, this option is currently considered the most cost-effective and will quickly pay for itself.

Sales of products

When you make a business plan for the production of drywall profiles, it is important to take into account the demand for these products in the market, which is consistently high. But, as in any other type of business, you must initially plan options for selling your product. For successful implementation, you need to focus on three options for buyers:

  1. Companies that do renovations own premises.
  2. Companies that provide services for the repair of housing and other real estate.
  3. Ordinary individuals who plan to make repairs at their place.

Income and expenses

To open a drywall profile business, you will need start-up capital in the amount of 2,029,000 rubles, which will be used to purchase:

  • beam cranes;
  • production line with roll forming machine;
  • delivery, installation and adjustment of all equipment;
  • purchase of all necessary tools;
  • company registration and related nuances;
  • rent / purchase of premises and its preparation;
  • acquisition of source material.

Provided that such a production line is loaded every day at half of its own capacity, you will be able to produce about 1 ton of goods in 24 hours. In total, the invested funds will return to you in two years.
