Product Description
After adding trace elements such as phosphorus, copper, chromium and nickel to the steel, the surface of the steel forms a dense and strong adhesion protective film, which prevents the corrosion from spreading and developing inward, and protects the matrix below the rust layer to slow down the corrosion rate. In rust is formed between the layer and the substrate of about 50 microns to 100 microns thick amorphous spinel and dense oxide layer and substrate metal stick fine, because of the existence of the oxide film layer prevents the oxygen in the atmosphere and water infiltration to the steel matrix, and slow down the corrosion to steel material depth development, greatly improve the atmospheric corrosion resisting capacity of steel materials. Weathering steel is a steel system that can be thinned, exposed or simplified, and can resist corrosion, prolong life, save labor and reduce consumption, and upgrade. It is also a steel system that can be integrated into the new mechanism, new technology and new process of modern metallurgy to make it sustainable development and innovation.ITEMlength(mm)width(mm)thickness(mm)weight(KG)SurfaceRegular 11800900225rust/unrustRegular 224001200240rust/unrustCustomizedas you needas you needas you needas you needas you need
