Advantages and Features
Extremely Long Lifespan, Virtually Maintenance-Free: Through the addition of alloying elements such as copper and nickel, weathering steel forms a dense and stable protective rust layer on its surface, preventing further corrosion. High-quality weathering steel can last for over 80 years—2 to 8 times longer than ordinary steel. This means that the billboards you order can be “installed once and enjoyed for years without worry,” significantly reducing long-term maintenance and replacement costs.
Suitable for Harsh Climates: It is particularly well-suited for outdoor advertising applications. Whether in humid and rainy conditions, salt fog corrosion (such as in coastal areas), or environments with severe industrial pollution, its corrosion resistance is exceptional. Compared to ordinary carbon steel, its resistance to chloride ion corrosion in coastal environments is more than three times greater. In regions prone to typhoons, when combined with a proper steel structure design, it can withstand strong winds of up to 10–12 on the Beaufort scale, ensuring safety and reliability.
