Product Overview

A36 Hot Rolled Steel Coil is the most widely used carbon structural hot rolled steel following ASTM A36 specification, favored by North American and global engineering buyers. Produced by continuous high-temperature hot rolling, the material delivers uniform metallurgical structure and consistent mechanical performance.

A36 coil is low carbon steel with excellent machining characteristics. It can be easily welded, bent, stamped and fabricated into various structural components. It serves as the primary material for building frames, warehouse structures, equipment bases, support brackets, pipe shells and general metal fabrication works.

Our factory supplies full range A36 hot rolled coils. Custom processing including slitting into narrow strips, flattening and cutting to fixed plate lengths is available.
