Lightweight frame made of rolled and welded profiles and SIN-beams.

Functionality and cost-effectiveness of the frame

The choice of the optimal load-bearing structure provides not only efficiency and functionality but also the best result in terms of economy.

• The length of the free span (the distance between the columns in the frame) and the distance between the frames.
• The height of the structure.
• Geological parameters of the site.
• Type and dimensions of foundations.
• Snow, wind, and potential seismic overloads.
• The distance between the structural columns.
• Internal structures and equipment, such as floors, crane tracks, windows, doors, gates, roofing light domes, adjoining existing buildings, local features.

Lightweight steel structures from SIN-beam (beam with thin corrugated wall or corrugated beam/sin beam).

Due to the sinusoidal corrugation of the thin (2-3 mm) wall of the welded I-beam, it was possible to significantly increase its stability and reduce the weight of the building frame. SIN-BEAMS are widely used for the production of large-span buildings, warehouses, public, sports, agricultural, commercial purposes, as well as for the construction of buildings with cranes capacity up to 30 tons.

Particular advantages are the frames of SIN-beams in seismic conditions and when exposed to dynamic loads.

Advantages of SIN Beams:

• Reduced usage of steel results in the money-saving. Around 30% of metal saved compared to welded and rolled beams at the same price per ton.
• Less deflection under dead weight. A straight beam overlaps an unsupported span of up to 60 m.
• Fully automated production. The time of supply for the building around 2000 m2 starts from 4 weeks.
• Completely stable construction. Ease of transportation and installation. Installation with one crane!
• Experience in engineering and construction. More than 5000 objects built with an area of ​​10 to 60 thousand m2 based on SIN beams in Europe and the CIS.
