steel box beam

When Bridges span is larger, the box girder is one of the best structure form, it's closed thin-walled section torsional stiffness is very big, for curved bridge and the bridge cantilever construction is particularly advantageous.Roof and floor has a large area, which can effectively resist the positive and negative bending moment and meet the needs of the reinforcement, has the good dynamic characteristics and the small contraction deformation values

Automatic submerged arc welding longitudinal seam penetration, electroslag welding clapboard,
According to customer needs, can be customized to map, cutting, punching, welding reinforcing plate, derusting paint.
