What Is Q295GNH?
Q295GNH is a high-weathering structural steel specified under GB/T 4171. Its controlled alloying additions (Cu, Cr, Ni and P) promote the formation of a dense, adherent rust layer that slows further corrosion, providing significantly better atmospheric corrosion resistance than plain carbon steel in comparable environments (typically cited as 2-8 times, environment dependent).
