Body Details

1 Product Overview

Our Shanghai warehouse maintains a large, year-round stock of hot-rolled coils and sheets. All products are sourced directly from top-tier domestic steel mills including Baosteel, Magang, Shougang, Angang, Jiuquan Steel, and Tangsteel. We offer two primary grades: Q235B carbon steel hot-rolled coils and Q355B low-alloy high-strength hot-rolled coils, manufactured in strict compliance with national standards.

Hot-rolled coils feature a natural black oxide surface, offering excellent toughness, weldability, and stable performance for stamping and bending. They are the universal base steel for structural steel buildings, construction machinery, bridge supports, equipment bases, and container manufacturing. Standard coil widths range from 1250mm to 1500mm, with thicknesses spanning 2mm to 20mm in full specifications. We support full-coil shipments, cut-to-length flattening, slitting into narrow strips, and custom cutting for projects of any size.
