Steel bar truss decking sheet
Instead of normal concrete formwork and composite steel decking. our product have advantage as follows:
1)saving labor,time,cost. (easy assemble,reinforced bar be prefabricated )
2)better mechanical structure model.
3)no fire resistant and corruption maintain demand.(compare with steel deck)
widely applied in steel structure floor,roof,steel-concrete composite slab
composite Steel decking | steel bar truss decking | |
Final concrete slab | Thick | SHALLOWER, saving space,saving concrete cost |
installation | easy | easy |
reinforcement | Welding steel mesh | Steel bar. Saving cost |
Plate(steel sheet) | AS SHEAR BONE,Bearing the loading after concreting | Just as PERMANENT formwork. .useless after concreting |
Plate Fire protection | demand | No need |
Plate corrosion protection | Maintenance demand.* specially around stud place where sheet harmed after welding | No need Perfect performance in marine environment |
across direction layout | Difficult to design&settle | Easy to settle |
Mechanical property | good | better |
Seismic performance
| bad | good |
Integrate cost | high | low |
Comfort due to slab autooscillation | bad | good |
