Zeman Group, which is inventor and patent owner of the current SIN Beams form, both fabricates SIN Beams and manufactures the equipment that fabricates SIN Beams.

Thin Sinusoidal Corrugated-Web I-Sections, are load-bearing elements that are manufactured by joining sinusoidal corrugated-web with the flanges that are manufactured by hot-milled plates. Although these webs are thin, due to the advantages of their forms, they can be used to fabricate wide-web sections, without any need for stiffening plates. The sinusoidal form of the web prevents local and overall buckling due to loss of stability before plastic limit load is applied.

Use of SIN Beams, which is wide among many companies in Europe, is becoming more popular throughout the world. SIN Beams, which are mostly preferred in long-span constructions such as shopping centres, plants, warehouses, bridges etc., despite the lightweight sections, facilitates higher strength due to its thin and wider webs. The state-of-the-art SIN Beams are an economic solution in long-span construction, minimizes fabrication periods and have higher load-bearing capacities. The material and time losses caused in ordinary welding process are eliminated by means of computer assisted fully automatic production line, and shorter of welding (welding 1m per minute) means also shorter spans of delivery.

Accordingly, when compared to conventional solutions, SIN Beams advantageous due to;

• Higher load-bearing capacity and lower design load,
• Being more economic in long-span constructions,
• Contribution to building height,
• Optimum weight in applicable building height,
• Minimum losses in production,
• Fully automatic production and shorter spans of delivery.
