The company operates Henan metallurgical rolling iron and steel factory all year round, providing steel products for various industries such as ow alloy high strength series, boiler and pressure vessel steel plate, power station engineering steel plate series, corten a grade material bridge structure steel plate, corrosion resistant steel plate, composite steel plate, high-rise building structure, die steel plate series, steel plate series for shipbuilding and offshore platforms, pipeline steel plate, alloy structure and other steel plates.

After adding trace elements such as phosphorus, copper, chromium, and nickel to Q355NH steel, a dense and highly adherent protective film is formed on the surface of the weathering steel, which prevents rust from spreading and developing, and protects the substrate under the rust layer to slow its corrosion . An amorphous spinel oxide layer of about 50 μm to 100 μm thick formed between the rust layer and the substrate is dense and has good adhesion to the base metal, which greatly improves the atmospheric corrosion resistance of the steel material, corten a grade material.
