WSJ - Dimensions - Wide sheet: 1.015 mm. Coverage: 1.000 mm. Lenght: upon request from continuous production process. Materials - Supports: galvanized steel, galvanized prepainted or plastified steel; stainless steel; natural or prepaintedaluminium. Foam: polyurethane selfextinguishing resins (PUR). Calculation principles - Load values are obtained on the basis of practical tests of capacity, processing the data with an appropriate mathematical method. Values reported represent the corrisponding loads either to the 1/200 span deflection, or to the half of the breakage shear value, or to the half of the breakage moment.
