HRB400 hot-rolled ribbed steel bars, commonly known as grade III threaded steel bars, HRB is the abbreviation for hot-rolled ribbed steel bars, and 400 represents the minimum yield strength of the steel bars reaching 400MPa.

HRB500 hot-rolled ribbed steel bars, commonly known as grade IV threaded steel, are high-strength concrete-reinforcing steels with a yield strength of not less than 500MPa. HRB is an abbreviation for Hot-rolled Ribbed Bar, and 500 represents the minimum yield strength of 500MPa. The product is manufactured using a micro-alloyed temperature-controlled rolling process, featuring crescent-shaped transverse ribs and two longitudinal ribs on the surface, resulting in extremely strong bond strength with concrete and significantly improving structural load-bearing capacity and seismic safety.

Steel wire rod is hot rolled round steel coil with smooth surface, manufactured by high-speed continuous rolling. It is widely used as raw material for wire drawing, nail making, welding electrode, wire mesh, fasteners and cold heading parts.

HRB400 deformed steel coil is hot rolled ribbed steel wire coil. "HRB" means Hot-rolled Ribbed Bar, with minimum yield strength of 400MPa. It features crescent ribs on surface, excellent flexibility and strong bonding force with concrete.

HRB500 deformed steel coil is high strength hot rolled ribbed rebar coil. "HRB" stands for Hot-rolled Ribbed Bar, with minimum yield strength of 500MPa. It is produced by micro-alloy controlled rolling, featured with crescent ribs, high bonding force and good flexibility.

Carbon steel U-shaped channel steel, also commonly known as hot-rolled U-shaped steel or ordinary channel steel, has a standard U-shaped cross-section and is mainly divided into two categories: hot-rolled U-shaped channel steel and cold-formed U-shaped channel steel. Made from Q235B and Q355B carbon steel, it is formed through hot rolling or cold bending processes, resulting in regular dimensions, high rigidity, and excellent load-bearing capacity. Surface finishes include natural black, hot-dip galvanized, and electro-galvanized, with the corrosion resistance level selected according to requirements.
