High-fold profiles are constructional elements and can be used on widespread roofs due to their high durability. Production offer includes T50, T55, T60, T92, T135, T150, T160 trapezoidal sheets of high durability parameters, which are used in building trading and industry buildings. The sheets can be used for load-bearing constructions as well as ceilings. Trapezoidal profiles’ durability depends not only on the sheet thickness or fold height but also on the bearings spacing, which should be specified in building design project. Load-bearing tables and assembly manuals are useful in designing and assembly of the trapezoidal sheets by our company.

 

Load-bearing tables developed for trapezoidal sheets ease designing as they save time which would be spent on calculating effective characteristics of thin-walled geometrical products of complex shapes.

 

To speed up the designing process our company developed a computer program which helps to make quick choice of the right trapezoidal sheet type having the right thickness by giving the calculative and characteristic load-bearing parameters, bay spacing, bay arrangement, deflection parameter and bearings’ width.

 

Trapezoidal sheets are produced with PN-EN 14782:2008 standard and CE marked.
