knowledge of round steel

Round steel refers to the solid section for circular strip steel. Its specifications expressed as a number of mm in diameter, such as "50" indicates that the diameter of 50 mm round steel. Round steel hot rolling, forging and cold drawn three kinds. The specifications of the hot rolled round steel of 5.5 to 250 mm. Among them: 5.5-25 mm small round steel are mostly with straight bundles of supplies, commonly used for reinforcing steel bar, bolt, and various mechanical parts; More than 25 mm round steel, mainly used in the manufacture of mechanical parts and carbon steel pipe billet.

Compared with other steel bar, round steel has its own uniqueness, main show is the points: 1, appearance is not the same, round steel exterior circle of light, no lines without ribs, and other steel surface appearance has a groove or a rib, thus causing the cohesive force of small round steel and concrete, and the other the cohesive force of steel bar and reinforced concrete. 2 ingredients are different, round steel (level 1) steel belong to the normal low carbon steel, more than other reinforcement for alloy steel. Three different intensity, low intensity of round steel and other steel with high intensity, the diameter of the same size of round steel compared with other steel bar, round steel can withstand strength than other bar is small, but the plastic is better than other mild steel pipe. the round steel before is pulled with large deformation, and other steel before be pulled deformation is much smaller.
