Steel Bridge

Home » Products » Steel Structures » Steel Bridge

The steel bridge refers to bridges constructed using steel as the main building material. Compared with the concrete beam bridge, a steel bridge usually features lower beam height and lighter weight. Thanks to the physical properties of steel such as isotropy, homogeneity, large elastic modulus, the practical construction work is able to be in line with theoretical calculation which demonstrates higher liability. The steel bridege designed and manufactured by our company has received many favorable comments from customers thanks to the high-strength, good rigidity and stability of our bridgework. Steel panels, hot-rolled steel, and stainless steel have been utilized and hot-dip galvanized in accordance with international standard to help maintain a relatively longer service life of the bridge.
