SMA570W aux intempéries japonaises à ultra haute résistance

SMA570W ULTRA-HIGH-STRENGTH JAPAN WEATHERING
SMA570W ULTRA-HIGH-STRENGTH JAPAN WEATHERING 3

The JIS G3114 standard outlines the specifications for SMA570W hot rolled atmospheric corrosion resisting steels, which are designed for use in bridges, architecture, and other welded structures. SMA570W Ultra-High-Strength Japan Weathering steel is a high-strength steel that is specially engineered to withstand harsh weather conditions. This type of steel is renowned for its exceptional strength and durability, making it an excellent choice for outdoor applications where corrosion resistance is crucial. It is commonly used in construction projects, bridges, and infrastructure that are exposed to the elements. It is important to note that steel products with a “W” designation must be non-coated or stabilized before use, while products with a “P” designation should be coated before use. SMA570W steel is available in plates, strips, sections, and steel flats.
