Problems solved by technology

[0002] As a kind of corrosion-resistant steel plate, weathering steel does not require galvanizing and antirust treatment, and there is no problem of pollution caused by zinc shedding. It has a good advantage in the field of transmission towers. Weathering steel towers will encounter different environments during use. , which leads to changes in its performance. The resistance of weathering steel towers has different performances under different conditions, but there is no documented research on the resistance of weathering steel towers.
