Why ASME SA588 Gr A weathering steel plate can be used on bridges

We can see ASME SA588 Gr A and so on weathering steel materials in many places, and we can see them on the bridge also. So why can ASME SA588 Gr A weathering steel plate be used on the bridge?

1. Corrosion resistance: many bridges are designed to be close to the water surface. Some even cross sea bridges, no matter how much the sea water or river water, will flood the bridge deck, which has higher requirements for bridge materials. If ordinary steel is used, corrosion will occur soon, while the application of ASME SA588 Gr A weathering steel plate in bridge engineering can effectively reduce these corrosion phenomena and make the bridge building more solid.

2. Beautiful appearance: ASME SA588 Gr A weathering steel plate will naturally rust after use for a certain period of time. The color of this rust can be changed with the change of time. This color element has been added to the design of many buildings to achieve a thick effect. ASME SA588 Gr A weathering steel plate is used in bridge engineering, which adds a thick texture to the bridge.

The above are the reasons why ASME SA588 Gr A weathering steel plate can be used on the bridge.
