DURASTEEL is a composite insulating board made of a calcium silicate core reinforced on both sides by galvanised steel covering shells (perforated). The punched lugs produced by the special punching processes are pressed under pressure into the core board, creating the high mechanical strength of DURASTEEL after the drying process has finished.

DURASTEEL is classified as A1 non-combustible according to DIN 4102.
