Truss Girder Welding Machine

 
Description of 3D truss girder:
3D truss girder is up-to-date rebar design used in modern building construction. 3D truss girder will be assembled with roll formed steel deck to be as combined template for site pouring. This kind of construction method reduces too much site rebar binding works, raises working efficiency and shortened construction period. Stress mode of truss girder is reasonable and so provides larger steel deck rigidity, usually no need temporary support. 


Description of 3D truss girder welding machine:
3D truss girder welding machine is a full automatic production line for produced 3D truss girder by three pieces ribbed and two pieces round rebar in reels.
3D truss girder welding machine is comprised of reel rebar pay-off, rebar straightening, truss rebar bending, welding, cutting and stacking sections.
The whole production line is operated by only one operator. Production speed can reach 18m/min.
