Note: The length of round steel is specified as follows

 A.Usual length (non-fixed length)

Ordinary steel:

Diameter ≤25mm …………………………………………………………………… Length 5~10m

Diameter 26~48mm………………………………………………………………Length 4~9m

Diameter 50~110mm………………………………………………………………Length 4~8m

Diameter ≥120mm…………………………………………………………………………Length 3~6m

 

High quality steel:

Various diameters……………………………………………………………………………………Length 2~6m

B. Fixed length (determined in the contract)

C. Double length (determined in the contract)

The delivery quantity of short round steel shall not exceed 10% of the total order quantity of a batch. The ordinary steel short ruler should not be shorter than 2.5m, and the high-quality steel short ruler should not be shorter than 1.5m.

3. The above are table of unit weight of round steel.

4. Round steel refers to a solid long steel bar with a circular cross-section. Its specifications are expressed in millimeters of diameter. For example, "50" means a round steel with a diameter of 50 mm.

5. Classification

Round steel refers to a solid long steel bar with a circular cross-section. The specifications are expressed in millimeters of diameter. For example, "50" means a round steel with a diameter of 50 mm.

Round steel is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250 mm. Among them: small round steel with a diameter of 5.5-25 mm is mostly supplied in straight strips and bundles and is commonly used as steel bars, bolts and various mechanical parts; round steel larger than 25 mm is mainly used for manufacturing mechanical parts or seamless steel tube blanks.

 

The difference between round steel and other steel bars: 1. The appearance is different. The round steel has a smooth round shape, no lines and no ribs. The surface of other steel bars has grooves or ribs, which results in a small bonding force between the round steel and concrete. , while the bonding force between other steel bars and concrete is large. 2. The composition is different. Round steel (first-grade steel) is ordinary low carbon steel, and other steel bars are mostly alloy steel. 3. The strength is different. Round steel has low strength and other steels have high strength. That is, compared with other steel bars, round steel with the same diameter can withstand less tensile force than other steel bars, but the plasticity of round steel is stronger than other steel bars. , that is, the round steel has a large deformation before being pulled off, while the deformation of other steel bars before being pulled off is much smaller.
