GB/T 4171 Q295GNH is a weather-resistant steel plate with atmospheric corrosion resistance due to its Cu-P-Cr-Ni alloy composition.
It offers a minimum yield strength of 295 MPa, balanced weldability (C≤0.12%), and good formability.
Commonly used in containers, building facades, and outdoor structures, it forms a protective rust layer, reducing maintenance needs.
This cost-effective material complies with China's GB/T 4171 standard, making it ideal for environments requiring durability without painting.
