It is essentially a triangulated system of straight interconnected structural elements. The most common use of trusses is in buildings, where support to roofs, the floors and internal loading such as services and suspended ceilings, are readily provided.

Truss girder welding machine

Truss girder welding machine, also named lattice girder welding machine, truss girder welding line, or lattice girder welding line.

The auto production welding line with an integration functions of coiled bar feeding, rebar straightening, auto welding, sizing cutting off and finished products delivery. The machines have been extensively used in floor support plate preset in building, dual-block sleeper of fast train rail way etc.
