Product Usage

Not only does Q235 possess toughness, weldability, and excellent plasticity, it retains strength while offering outstanding cold-bending performance. It is perfect for welded structures, including factory buildings, steel bars, towers, boilers, bridges, containers, vehicles, and more. Q235 can also be used as mechanical parts, such as stands, stressed rods, nuts, connecting rods, brackets, and other components. Q235 and varying grades of steel plates can be cut to specification.
