In multi-storey buildings and high-rise steel structure buildings, steel composite decking bearing plates and concrete are combined to form a whole. In such structure, the bearing plate bears construction load during construction, and acts with concrete during use to bear use load.

DFP555 Closed Type Metal Decking Sheet Series is developed by Wiskind with the help of Tianjin University.This floor decking system is connected to concrete par by shear force connecting piece.This combined floor decking series fully use the advantage of the two materials.The advantages of the floor decking system are light weight,high strength, big stiffness, easy construction and industrial production.
