Hideck 75

(structural steel formwork - composite slabs)

Our new product (HIDECK 75), is ideal for use in steel framed buildings as they provide a quick and economical form of construction. It is evident that with its high strength it is suitable for bridging long spans offering versatility and significant cost benefits.The upper trapezoid surface has been reinforced against local buckling with additional reinforcement in its middle. On both body and base the embossments offer better bonding between the steel sheeting and concrete.
