Introduction Of Steel Bridge

A steel bridge is a bridge that uses steel as the main construction material. It has the characteristics of high strength and high rigidity. Compared with concrete bridges, it can reduce the beam height and self-weight.

Due to the isotropy of steel, uniform texture and large modulus of elasticity, the working conditions of the bridge are more consistent with the calculation assumptions. In addition, steel bridges generally adopt factory prefabrication, site splicing, short construction period, convenient processing and not affected by the season . However, steel bridges have poor fire resistance and corrosion resistance, and require frequent inspections, maintenance, and high maintenance costs.
