Cheapest Factory Hrb400 Steel Rebar - Hot-rolled round high-quality carbon steel wire rod – Ruigang

Description:

Hot-rolled steel bars are finished steel bars that have been hot-rolled and naturally cooled. They are made of low-carbon steel and ordinary alloy steel at high temperature. They are mainly used for reinforcement of reinforced concrete and prestressed concrete structures. One of the most widely used steel varieties. Most of the steel bars with a diameter of 6.5-9 mm are rolled into wire rods; those with a diameter of 10-40 mm are generally straight bars with a length of 6-12 M. Hot-rolled steel bars should have a certain strength, namely yield point and tensile strength, which is the main basis for structural design. There are two types of hot-rolled round steel bars and hot-rolled ribbed steel bars.

High-quality carbon steel hot-rolled wire rod can be used for processing steel nails, pins, steel wire ropes, steel cables, steel strands, hose steel wires, spring steel wires, etc. and excellent drawing performance.
