Round steel rolling, forging into system and cold pull 3 kinds. Hot-rolled round steel specification for the 5.5-250 mm. Among them: 5.5-25 mm small round steel mostly with straight into bundles of supply, commonly used reinforced, bolts and all kinds of mechanical parts; More than 25 mm round steel, is mainly used to produce the mechanical parts or be seamless steel tube billetHot-rolled steel and other difference: 1 appearance, round steel exterior light round, no lines without ribs, other steel surface appearance have groove or a rib, this circular steel and concrete caused the rapping smaller, and other steel and concrete rapping. 2. The ingredients, round steel (level 1 steel) belong to ordinary low carbon steel, alloy steel reinforcement for other more. 3 strength, round steel low intensity, and other high strength steel, namely the diameter size of the same round steel reinforced with other than to withstand round steel tension than other reinforced small, but the round steel reinforced plastic than other strong, namely in distant is pulled before much deformation, and other steel is pulled in before the deformation are much smaller.
