Because the SMA490BP steel for bridge construction product cutting parts are smooth and beautiful, the surface quality is good, and the dimensional accuracy is high, its mechanical properties and process performance are better than hot-rolled thin steel plates, and it is widely used. Before leaving the factory, both sides of the steel plate are coated with neutral grease to prevent rust.
With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel SMA490BP steel for bridge construction product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the SMA490BP steel for bridge construction plate should be derusted before cutting.
Weathering steel is mainly used in railway, vehicles, bridges, towers and other steel structures exposed to the atmosphere for a long time. SMA490BP steel for bridge construction. Weathering steel is used to make structural parts such as containers, railway vehicles, oil derricks, seaport construction, oil production platform and containers containing hydrogen sulfide corrosion medium in chemical petroleum equipment. Weathering steel has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving, which benefits the weathering steel component manufacturers and users.
