About ArmourDeck Steel Formwork
ArmourDeck is a permanent steel formwork decking system for suspended concrete slabs. The profiled steel sheet acts as both formwork and tensile reinforcement for composite concrete floor slabs, eliminating temporary propping and reducing construction time. Steel Formwork Decking offers excellent spanning capabilities, high composite strength and minimal deflection. It is ideal for both concrete and steel frame construction. This is roll-formed from hot-dip zinc coated, hi-tensile steel strip in a range of base metal thicknesses (BMT) conforming to AS1397.
