GB/T Q690NH Weathering Steel Rust-Proof

GB/T Q690NH Weathering Steel

Why Engineers Choose Q690NH Weathering Steel​

Exceptional Weather Resistance: Regular steel rusts quickly when exposed to the elements. However, Q690NH forms a self - protecting patina. This layer acts as a shield, stopping further corrosion. As a result, there's no need for frequent painting or rust - prevention treatments, saving both time and money.​

Great Mechanical Properties: With a high yield strength of 690 MPa, it can handle heavy loads. It also has enough flexibility to bend a bit under stress without breaking. This is important for structures that experience different types of stress during their lifespan.​

Cost - Effective in the Long Run: Although it may cost more at first than some ordinary steels, its long service life and low maintenance requirements make it cost - effective. Structures made from Q690NH steel don't need to be replaced often, resulting in long - term savings.​
