Round steel is a long, solid steel bar with a circular cross-section. Its specifications are expressed in diameter, unit mm (mm), such as "50mm" which means the diameter of 50mm round steel.
Round steel is classified as hot rolled, forged, and cold drawn. Hot rolled round steel is 5.5-250 mm in size. Among them: 5.5-25 mm small round steel mostly to straight strips into bundles of supply, commonly used for reinforcing bars, bolts, and various mechanical parts; Round steel larger than 25 mm, mainly used in the manufacture of machine parts, seamless steel pipe billet, etc.
Small round steel with a diameter of 5.5-25mm is generally supplied in bundles. Small round steel is commonly used for reinforcing bars, bolts, and various mechanical parts. Generally, round steel with a diameter greater than 25mm is mainly used for manufacturing mechanical equipment, parts, and tube billets of seamless steel pipes.
The difference between round steel and other steel bars:
1, The appearance is not the same: The round steel appearance is round, with no lines and no ribs, the surface appearance of other steel bars is engraved or ribbed, so that the adhesion of round steel and concrete is small, and the adhesion of other steel bars and concrete is large.
2, The composition is not the same: Round steel (first-grade steel) belongs to ordinary mild steel, and other steel bars are alloy steel.
3, The strength is not the same: The strength of round steel is low, the strength of other steel is high, that is, the diameter of the same round steel compared with other steel bars, round steel can withstand the tension is smaller than other steel bars, but the plasticity of the round steel is stronger than other steel bars, that is, the round steel has a larger deformation before being pulled off, and the deformation of other steel bars is much smaller before being pulled off.
