Modern steel door structures are not exclusively reliable protection of the structure, but also an element of the interior and exterior. The technology of creating steel blocks is very noteworthy, which is worth considering.
Steel Door Blocks: Required Business Start Equipment
Steel metal systems in turn
The main attribute of each structure is concluded in the presence of a reliable overlap of the entrance. It is necessary to specify the production process of stages of manufacturing iron structures.
So each manufacturer tries to make the manufacture of steel doors more upgraded, and the developers in modern times use exclusively metal blocks for overlapping the entrance in new buildings. To date, manufacturers try to improve not exclusively technical indicators of systems, but the aesthetic side of the product from a design point of view relative to the latest trends in the interior stylistic fashion.
Business for the production of iron structures is nothing particularly difficult, therefore, to give life to such an entrepreneur into the forces. So the list of necessary equipment for production goals is permissible to accommodate into a single table:
| № | Equipment | Notes to Equipment | Cost of equipment |
| Machine for cutting steel sheet (metal) | Laser or plasma can be used, since cutting on such machines occurs quickly and evenly | From $ 1 800.00 | |
| Metal bend press (sheet bib) | From $ 11 200.00 | ||
| Welding complex for finishing and point welding | It is permissible to use conventional devices or specialized welding machines | From $ 1 600.00 | |
| Installation for powder painting products: to prepare the surface of the block to painting | It can be a special painting chamber | From $ 980.00. | |
| Installation for the powder color of the product: Painting compressor, Paint gun and Polymerization Camera (furnace) | Instead of the polymerization stage, the surface coating can be used after the color of two layers of special vandal resistant varnishes | From $ 2 400.00 |

The above-mentioned list of equipment refers to a minimum of the necessary equipment. So
Machine for manufacturing design
The global market is available ready-made integrated steel block production lines, where all the above machines and installation are combined. Typical production lines can be fully automated or partially when a person's hand should be applied to a specific step.
Such automated lines are manufactured in peace with foreign manufacturers and are endowed with such a list of equipment:
- Installation of plasma cutting of metal;
- Metal sheets bend press;
- Automatic coordinate welding door shells;
- Two welding machines with conductor ticks;
- Two points of the final welding process occurring in a special medium (carbon dioxide).
The typical line does not provide for the presence of paint box, which is equipped separately. The performance of the line is reduced to the production of 10 blocks for one hour of time, but also during control, at least 10 people. The approximate cost of such a production continuous process is reduced by any, no, but to $ 100 thousand.
Metal construction shop
Workshop for the manufacture of metal structures
At the moment, the manufacture of steel doors is performed on various technologies, but in fact they are all endowed with uniform source aspects. The main part of the processes of production technology should occur in separate rooms, so the area is obliged to provide for the following workshops:
- Workshop where metal and the preparation of raw materials are made;
- Workshop where metal sheets and profile rental are happening;
- Workshop where the welding assembly process is performed (production line);
- Shop for painting products;
- Finishing and decorative workshop, provided that the finishing material is made on the territory of the enterprise, and not purchased in the finished form;
- Assembly control workshop, where blocks are equipped with lock and other mechanisms;
- Storage facilities for storing finished products.

Each of the workshops should meet the special requirements for fire safety. Thus, the premises should be decorated (floors, walls), at least, non-combustible materials, and to be equipped with air-exhaust ventilation.
Production and technological process of manufacturing steel blocks
The manufacture of iron doors relative to the technology provides a certain sequence of production actions that are spelled out in specialized documentation (route or technological card), where:- Basic requirements for the source quality of the material used;
- Rules for transporting raw materials and finished product, acceptance of material and storage of input blocks;
- The documentation of the Special Requirements indicates a set of technical requirements for each stage of the process;
- Specified methods for testing quality and control;
- Many technical conditions are indicated (manufacturing TU), which are compiled in accordance with the testimony of GOST 31173-2003.
Basic technological steps of steel structures:
Preparation of raw materials.
At this stage, the metal material is subject to sorting. The marking of sheets is evoked, the presence of deformations, which manifest themselves mainly after the transportation process or rolled steel is being checked. At this stage, the scale and corrosion are also removed from the material. Storage of metal rolling in warehouses should be made on racks or sheets are stacked in the stack.
Marking and cutting blanks.
The manufacture of doors starts with the correct cutting of metal sheets relative to the surface of the templates using the pulps and kerners.
Processing billets and details.
The door box profile is created on sheet bending equipment.
Billets for future input blocks are aligned to eliminate sowing and irregularities. So in the process removed the surface layer of steel in the areas of cuts. The sawtorm can be performed manually using simple files, so in specialized swinging machines.
The processed billets are sent to the stamping machine on which the holes of the most diverse diameter are done in the details of the installation on the design of the fittings, lock systems.
Assembly process and welding

The door leaf is assembled using contact welding. Typical welding technology eliminates deformation damage to the door of the door and ensures the complete exclusion of welding seams on the surface.
Castle systems are installed on metal structures at a time with the installation of rigidity ribs, on areas reinforced with metal plates. Created, kind, technological pockets. At this stage of the canvas and are insulated. Inside the canvases the non-combustible soundproofing and insulating material.
The loop to the assembled product are often welded manually.
Paintwork.
After the construction assembly is completed, the block is painted. The compositions are applied solely on the polished, purified, degreased surface. Methods for applying several:- Jetty;
- Pneumatic spraying;
- Spraying in the electrostatic field.
For the process, one of several colors can be used in a variety of colors range:
- Powder;
- Nitro;
- Hammer;
- Graphite.
Decorative decoration of structures.
Often metal doors are decorated with protective coatings, molded, laminated finishing panels. Decorative decoration by production can be purchased at the finished form. As a trim, it can be used:
- Dermatin, leather, vinylisco;
- Wood lining;
- MDF panels, chipboard;
- Natural wood;
- Thermal fillet with imitation under natural wood is either monophonic;
- Decorative forging elements;
- Natural wood veneer.
Installation of fittings, castle systems.
Often the cutting of fittings is done manually. To avoid the characteristic metal sounds emanating from the design of the input blocks, and for thermal insulation properties, the door canvases are covered with special depreciation materials:
- Rubber seals;
- From rubber;
- Silicone seals.
