🟧 Product Overview

Q195 Structural Carbon Steel Coil is a low‑carbon steel grade under the GB/T700 standard. It offers excellent weldability, good ductility, and reliable forming performance, making it suitable for construction, metal fabrication, machinery parts, and general engineering applications.

Q195 is widely used for light‑to‑medium structural components, welded parts, brackets, frames, and general fabrication. International equivalents include mild steel grades such as ASTM A36 (approx.), SS400, and S235JR (approximate reference only).
