1: Receipt of rolled metal products to the warehouse of the plant

All rolled metal products that come for further processing are confirmed by all the necessary certificates of conformity. Therefore, we guarantee the consumer that all products will be made only of high quality material.

2: Primary cleaning of rolled metal

Before cutting, all rolled sheets are shot blasted, which improves the quality and precision of the workpiece parts. This is the best process for cleaning scale, rust, burrs, mould or sand in such a short period of time. All this is carried out on the shot blasting machine of the company “Gietart” (Holland).

3: Preparation of belts for beams

To produce corrugated beams, high-performance high-quality metal cutting into strips is required, which will be further used as beam shelves. Installation of the German The Messer product is a machine for longitudinal cutting of metal, which carries out absolutely precise cutting of sheet steel into strips of the desired size (the device is equipped with CNC control).

4: Facing and drilling of belts

After the cutting operation, the belt ends are machined (faced) and, if necessary – drilled (drilling holes) on a CNC machine by the Italian company Ficep.

5: Corrugation blank (wave wall of beam)

The main element of the corrugated beam is a corrugated wall, for its manufacture, cold-rolled steel coil is used, 2-3 mm thick.
The wall forming process itself takes place in several stages: loading the roll into the unwinder unit; cutting the sheet to the required size; passing the workpiece through the forming rollers.
After that, the wave-shaped billet goes to the conveyor for further assembly and processing of corrugated beams.

6: Folding and welding of corrugated beams

Assembling and welding of the beams is carried out on a high-performance robotic line manufactured in Austria by Zeman, with the use of welding robots by Abb (Switzerland). The corrugated wall sheet is connected to the shelves with a continuous single-sided welded seam. The small thickness of the wall allows to avoid mushrooming of the beams. Stability of welding modes and the entire welding process is fully controlled at the software level. Beam welding speed approx. 1 min/linear meter.

7: Finished beams processing and labeling

After welding, the beams are transferred to the conveyor and fed to a CNC-controlled saw for cutting to the required size. Also, holes are drilled and labelling is applied to the finished steel beams (Ficep machine).

8: Assembly and welding of metal structures

After preparation, the trunks from corrugated beams enter the station of assembly and welding. All the necessary parts are prepared in advance on the plasma cutting machine “Hypertherm” (USA), guillotine shears “Erfurt” (Germany) and, if necessary, on the bending machine “Erfurt”. Assembly of structures is carried out on the basis of project documentation of the DMS stage (detailed metal structures). Welding of parts of assembled products is carried out by highly professional welders with the help of semi-automatic welding machines by Fronius (Austria).

9: Cleaning of metal structures before painting

All finished products are subjected to portal type shot blasting on the machine by Gietart (Holland). Specially selected technological modes and blasting parameters provide 100% metal cleaning and absolute preparation for further coating with paint and varnish.

10: Painting of metal structures

The painting section has equipment for pneumatic spraying. Painting is carried out in a closed warm workshop, where stable temperature and humidity conditions are artificially created, which allows the coating to dry in the shortest possible time and in compliance with all technological conditions. Painting is carried out with alkyd primer for metal.

11: Shipment of finished products

After painting, the finished products are loaded into transport for transportation. The carrier is provided with a consignment note (CN).
