Trapezoidal sheet: profile, effective width and load tables
Profile geometry and coverage using 27/200 as an example, with load-table conditions to check.
Sources checked:Understand the Material
Specify profile geometry, base steel and coating together. The dimensions below are an example of İzocam Tekiz ÇK 27/200; they are not Alya production or stock dimensions.
Effective width is the net coverage after overlap. A load table is valid only with the manufacturer’s span, support, deflection and loading conditions. A table for one profile cannot be transferred directly to another manufacturer’s similarly named product.
