1.Strong friction and shear performance
The closed-type floor decking sheet uses special closed rib design and its vertical shear performance is good . Under the limitation allowance of the truss floor deck’s design loads,steel deck and concrete don’t slip off each other.
2.Perfect fire-resistant performance
Rib is completely encased in concrete,similar t reinforcing steel bars in the concrete slab which is site pouring.The closed-type composite slab can completely substitute the sagging moment reinforcing steel bars for pulling in the floor and can be up to 1.5 hours of fire-retardant coating .
3.Excellent floor decking sheet section
The closed-type composite slab has greater effective height,during the stage of use,it can provide greater resistance to sagging moment.
4.Slot-tye suspension system at the end of sheet
It is for the installation of ceiling,hung ceiling,water and electricity pipe,etc,without drilling,welding,during the stage of using,it can be moved,removed and reinstalled as needed.
5.East and fast to construct
It does not require any plug at the end ,and there is no leakage of plasma phenomena,it can shorten the construction period.
6.Flat appearance f the end of sheet
The end of slab is flat and beautiful for the building which don’t want ceiling.
7.Effectively reduce the height of the sheet
According to the requirement of fire safety and anti-tremor,the total thickness of the closed-type corrugated floor decking sheet is only 110-130mm,30-40mm less than the open-type,so it reduces the weight and cost and add the net height.
The closed-type pressure plate can substitute the sagging moment reinforcing steel bars at the end of sheet,and there is no need to paint any fire-retardant coating,it reduces the steel amount and then lowers the cost.
