Weather resistant steel SPA-H is a type of weathering steel known for its durability and corrosion resistance. It develops a protective rust layer when exposed to the elements, which helps prevent further corrosion and maintains structural integrity. This makes it ideal for outdoor applications, such as furniture, sculptures, and architectural elements. Its aesthetic appeal, with the distinctive rust-like appearance, also makes it popular in modern design.This Weather resistant steel SPA-H has excellent corrosion resistance, can maintain a stable appearance and strength for a long time in the outdoor environment, and is very suitable for outdoor furniture, fire pits and other products
