Production of metal structures is a high-tech process that requires the availability of modern equipment, qualified personnel and a high culture of production.

Reception of raw materials at the plant
Input control
Sorting by profiles and grades of steel
Marking
Storage before delivery to the processing shop
1
Reception of raw materials at the plant
We have our own laboratories, which make tests of products for compliance with chemical composition (chemical-analytical, spectral analysis) and mechanical tests for compliance with physical and mechanical properties, allows us to perform proper control of rolled products and confirm their compliance with the stated specification.

Straightening of rolled metal
Straightening of rolled metal
Special multi-roll equipment for straightening of plates and shaped rolled products allows to eliminate possible gaps arising due to the non-planarity of the connecting elements, to ensure the design bearing capacity of the structures.

Shotblast cleaning of rolled metal
Shotblast cleaning of rolled metal
Cleaning of surface of rolled metal with the help of shot blasting machines equipped with powerful turbines (shot speed reaches 90 m/sec) allows to completely remove rust, scale, pollution and ensure a surface roughness of at least 40-60 microns, ensuring reliable adhesion of paint and varnish materials to the metal surface after their application.

Processing of details
Processing of details
Modern automated CNC equipment ensures high quality and accuracy of manufacturing of structures. Automatic drilling equipment with high precision forms holes for bolted connections with an accuracy of at least 0.5 mm, including for installing high-strength bolts.

All edges are blunted with a blunting radius of 2 mm according to EN 1090. Instrumental control and marking of manufactured details is performed.

Assembly and welding of structural elements
Assembly and welding of structural elements
Welding is carried out according to the certified WPS and WPQR welding technology in production workshops equipped with beam stands and lines of welding machines of various modifications, which allow performing various types and methods of welding. For each project, a welding instruction is developed, which specifies the welding technology, process performance parameters, conditions for intermediate and final control of welds in accordance with ISO 3834-5. Ultrasonography, X-ray control of welds is carried out.

Shotblast cleaning of metal structures
Shotblast cleaning of metal structures
Additional shotblast cleaning of finished metal structures in shot blasting machines removes dirt, dust, and rust accumulated during their manufacture. Dedusting and degreasing of structures is carried out to ensure high adhesion during the subsequent application of paint and varnish materials.

Anti-corrosion protection of steel structures
Anti-corrosion protection of steel structures
Design requirements for anti-corrosion protection of metal structures are secured by applying paint and varnish materials by the method of airless application to the surface of structures. Availability of the complete cycle for hot-dip galvanizing of various structures (power line supports, stairs, structures protecting freeways, lighting poles, etc.). Galvanized metal structures have a much longer service life and coating quality.

Drying of metal structures
Drying of metal structures
Drying of metal structures with dimensions up to 3600*3600*24000 mm is done in special drying halls, which speeds up the drying time and contributes to more effective execution of contractual obligations.

Packaging and loading into vehicle, delivery to construction site
Heavy-capacity crane equipment equipped with magnetic washers for loading structures onto the vehicle allows to avoid deformation during loading. Various packaging schemes prevent damage during transport.
