Product details

Product Description:

Round steel refers to the solid long steel with circular section. Its specification is expressed in diameter (mm). For example, "50mm" refers to round steel with a diameter of 50mm.

Classification by process:
Round steel is divided into hot rolling, forging and cold drawing. The specification of hot-rolled round steel is 5.5-250mm. Among them, 5.5-25mm small round steel is mostly supplied in bundles of straight bars, commonly used as reinforcement, bolts and various mechanical parts; Round steel larger than 25mm is mainly used for manufacturing machine parts, seamless steel tube billets, etc.
Classification by chemical composition:
Carbon steel can be divided into low carbon steel, medium carbon steel and high carbon steel according to chemical composition (i.e. carbon content).
Classification according to steel quality:

According to the quality of steel, it can be divided into ordinary carbon steel and high-quality carbon steel.

Differences between round steel and other reinforcement:
1. The appearance is different. The round steel is smooth and round, without wrinkles or ribs, and the surface of other steel bars is carved or ribbed, which results in a small bond between the round steel and the concrete, while the bond between other steel bars and the concrete is large.
2. The composition is different. Round steel (Grade I steel) belongs to ordinary low carbon steel, and other steel bars are mostly alloy steel.
3. The strength of round steel is different. The strength of round steel is low, while that of other steels is high. That is, compared with other reinforcements, round steel with the same diameter can bear less tension, but its plasticity is stronger than other reinforcements. That is, round steel has greater deformation before being pulled off, while other reinforcements have much smaller deformation before being pulled off.
