Material Overview
Carbon steel is the workhorse of industrial fabrication — offering high strength, excellent weldability and finish-friendly surfaces at the most competitive price point. We process cold-rolled SPCC / DC01 for enclosures, structural Q235 / A36 for frames, and galvanized SGCC for outdoor durability — covering everything from server cabinets to heavy machinery and HVAC ductwork.
