Differences between Round Steel And Other Steel

Round steel refers to the circular cross-section solid bar of steel. Its specifications is expressed by diameter in millimeters (mm), such as '50mm' means a diameter of 50 mm round steel.

Round steel is divided into hot-rolled, cold-forging and cold drawn round. Specifications of Hot rolled round steel is between 5.5mm and 250 mm. Most of 5.5-25 mm round steel is supplied by straight bundles, commonly used for steel, bolts and various mechanical parts; For the greater than 25 mm round steel, mainly for the manufacture of machinery parts, seamless steel pipe tube and so on.

Round bar has some difference with the other round steel bars, The first is appearance is not the same, round shape is light round, no pattern no rib, but other steel surface has a ribs, This resulted in round bar has small adhesion with concrete.The second is different component, round steel belongs to the ordinary low-carbon steel, other bars are more alloy steel. The last one is not the same intensity, round bar can withstand smaller tensile than other steel, but round has stronger plasticity than other steel,
