The Promat® Steel Calculator is an online tool designed to calculate the necessary (mandatory) fire protection of steel support structures. Based on a few criteria specific to your project, you can calculate the thickness of our fire resistant panels (PROMATECT®-250, PROMATECT®-L and PROMATECT®-100), our fire-resistant paints (Cafco SPRAYFILM® WB3) and our fire-resistant spray mortar (CAFCO® 300 and Cafco FENDOLITE® MII).

In short, a simple tool for complex calculations!
