Do you need a special stainless steel formwork since the formwork cannot be removed after completion, and moisture could lead to rust streaks and rust stains?

Do you need a formwork (made of galvanised material) for concrete floors, casing, expansion joints, for shrinkage cracks joints, with dowel connection for power transmission at the joints, with bracing on the joint edges to hinder chipping of the concrete?

We have developed a system which is flexible and which makes floor casing mountable in the shortest time by wedging the elements under one another. We manufacture your needs quickly and economically.
