The strength grade and toughness of bridge steel in China are continuously improved, the welding performance is continuously improved, and the suitable thickness of Q355NH weathering steel plate is gradually improved. Railway bridges Steel for steel, highway bridges, and steel for sea-crossing bridges have become the mainstay of steel for bridges in China. The Q355NH weathering steel that meets the development requirements of the times will be the main direction for the development of bridge steel in China. Q355NH weather-resistant bridge steel has been applied in China, but it is necessary to establish or improve the relevant national or industry standards for the use of Q355NH weather-resistant bridge steel.
