AISI Q355 Steel Arch Girder Bridge Continuous Plate Weather Resistant

The structure of arch bridges fixes and supports the arc-shaped main members in the horizontal direction at both ends, and the bridge consists of a deck arch, a half-through arch, and a through arch, which are named for their positions relative to the girders. In general, arch bridges are structured to guide all forces to the arch ribs and support horizontal reactions on the ground, or have a tied arch structure that makes the girders on the road surface bear the horizontal reactions produced at both supporting points. Tied arch bridges include the Langer, Lohse, and Nielsen types. The applied spans are generally about 50 to 170 meters.

About Us

We always use high-quality structure steel in certified grades. Prefabrication of steelwork in our highly controlled factory conditions leads to high quality work at minimum cost. The excellent quality control is achieved through a thorough testing regime at the steel mills and during the fabrication processes of cutting and drilling, assembly, welding, and protective treatment. The quality assurance that is attained should give confidence to all clients and engineers who specify steel for their bridge project.

We will use Corten Steel for most type of bridges. Corten steel is a high strength low alloy steel that in suitable environments forms an adherent protective rust ‘patina’, to inhibit further corrosion. The corrosion rate is so low that bridges fabricated from unpainted weathering steel can achieve a 120 year design life with only nominal maintenance.
