General description
 Self-supported steel bar truss deck production line is independently produced by Zhejiang Willing Techology Co.,Ltd consists of truss welding line bottom panel forming machine and board spot welding machine. combining mechanism, electricity,hydraulic and pneumatics with microcomputer control, it performs whole set production process of steel moulding board's truss,galvanized steel forming and assembling&welding.The line's annual production capacity reaches 300'000 square meters.
 
Machine feature and function
Self-supported steel deck panel is a new type steel structrural building material develoed for steel construction industry in recent years.It's now widely applied in steel structural floor deck,bridge,railway and many other places.It's featured by light structure ,high strength and factory production. This construction method of pouring concrete onto steel deck can reduce site workload greatly and also shortens construction
