Cu-P weathering steel plate

Cu-P weathering steel plate is a special steel with excellent atmospheric corrosion resistance. This steel can form a protective layer on the metal surface by adding a small amount of alloy elements such as copper (Cu) and phosphorus (P) to the steel, thereby improving the atmospheric corrosion resistance of the steel. In addition to copper and phosphorus, elements such as chromium (Cr) and nickel (Ni) can also be added to further refine the grains, improve the mechanical properties of the steel and improve its strength and toughness.

SPA-H weathering steel plate

SPA-H weathering steel plate is a high-strength, corrosion-resistant steel plate with excellent atmospheric corrosion resistance, high temperature, abrasion, forming, fatigue, toughness and plasticity. SPA-H steel plate can form a dense protective layer between the stainless layer and the substrate, which can prevent oxygen and water in the atmosphere from penetrating into the steel substrate, slowing down the development of rust, thereby significantly improving the atmospheric corrosion resistance of steel.

09CuPCrNi-A weathering steel plate

09CuPCrNi-A weathering steel plate is a high-strength weathering steel with excellent atmospheric corrosion resistance. This steel material forms a dense protective layer on the surface of the metal matrix by adding a small amount of copper (Cu), chromium (Cr), nickel (Ni) and other alloy elements to ordinary carbon steel, thereby improving its atmospheric corrosion resistance. The weather resistance of 09CuPCrNi-A is 2 to 8 times that of ordinary carbon steel, and the paintability is 1.5 to 10 times that of ordinary carbon steel.

Q355GNHL weathering steel plate

Q355GNHL weathering steel plate is a kind of high weathering resistance low alloy steel. It improves the atmospheric corrosion resistance of steel by adding a small amount of copper (Cu), phosphorus (P), chromium (Cr), nickel (Ni) and other alloy elements to ordinary carbon steel. The grade of this steel is composed of "yield strength", the first letter "Q" of the Chinese pinyin of "high weathering resistance", "GNH", the lower limit of yield strength and quality grade (L). "355" means that its yield strength is 355 MPa, and "L" represents the quality grade.
