| Contrast point | Deck truss VS. Corrugated steel deck |
| Construction period | Comparing to profiled steel deck,steel truss deck can reudce 60-70% steel bars banding quantities,and reduce construction period for each floor. |
| Quality | 1,Steel truss deck is produced by computer numerical control equipment,steel bar distance is evenly arranged and even by force; 2,Concrete protection layers thickness and floor slab thickness can be effectively guaranteed; 3,Base mould is not involved in the use phase,so it doesn't need to consider fireproof and anticorrosive problem. |
| Convenient and safe | 1,The base mold and steel rebars of deck truss are integrated in factory,which make it easy construction; 2,Deck truss can reduce the bundling of steel rebars.It not only saves labor costs, but also reduces the safety hazards of reinforcing steel bars on site; 3,The two-way stiffness of the floor slab is close, which is good for building earthquake resistance. |
| Economic rationality | 1,The force mode of steel truss deck is reasonable, the material selection is economical, and the comprehensive cost advantage is obvious; 2,The height of the truss and the size of the steel bars of deck truss can be adjusted to accommodate large-span slabs; 3,Steel truss deck can be designed as a two-way board; 4,The bottom mold of truss deck is flat and beautiful, which increases the floor usage by 20%. |
| Cost reducing | 1,Steel truss deck can reduce the labor consumption; 2,Deck truss can reduce the cost of rented construction machines and construction management cost; 3,Deck truss can shorten the installation time,thereby speeding up the capital turnover, which reduces the cost. |
