Carbon Steel

ASTM A36 hot rolled carbon steel plate
ASTM A36 hot rolled carbon steel plate is a general-purpose low-carbon structural steel produced to ASTM A36/A36M and supplied in the hot-rolled condition, with a minimum yield strength of 250 MPa and tensile strength of 400–550 MPa. Its low carbon content (0.25% max.) delivers excellent weldability without preheating, plus easy cutting, punching, drilling and bending. Widely used for building and industrial structures, bridges, machinery frames, tanks and silos. Cut-to-size service and mill test report available for every lot.

ASTM A500 carbon steel square tubing
ASTM A500 carbon steel square tubing is cold-formed welded (ERW) carbon steel structural tubing produced to ASTM A500/A500M — the specification most commonly cited for hollow structural sections (HSS) in North America. Square sections are typically supplied in Grade B (minimum yield 317 MPa / 46 ksi, tensile 400 MPa / 58 ksi) or Grade C (minimum yield 345 MPa / 50 ksi, tensile 425 MPa / 62 ksi). Typical applications include building columns, structural supports, trusses, handrails, sign posts, communication towers and equipment frames. We can provide hot-dip galvanizing and processing services such as fixed-length cutting, punching and beveling.

high manganese steel plate manufacturers
Engineered for extreme wear and heavy impact, our high manganese steel plates (Mn13 / Hadfield) feature outstanding self-work-hardening capabilities. Under mechanical shock, the surface hardness escalates from 200 HB up to 600 HB, creating an ultra-durable wear barrier while maintaining a tough core to prevent fracture.
