Products Description
GB/T 4171 Q310GNH Weather Resistant Steel Plate is a weather-resistant steel conforming to China's GB/T 4171 standard, with a yield strength not less than 310 MPa, a tensile strength range of approximately 450–630 MPa, and an elongation generally not less than 20%.
Common supply thicknesses range from 2–40 mm, with widths of 1600–3000 mm and lengths of 6000–12000 mm.
In atmospheric environments, Q310GNH steel plate forms a dense, stable rust layer, offering corrosion resistance 2–8 times greater than ordinary carbon steel and extending service life by 30–50 years.
As a weathering steel, Q310GNH hot rolled corten steel plate is widely used in vehicles, bridges, towers, containers, outdoor structures, and construction machinery.
