What's the difference between round bar and screw steel? Which one is cheaper on the market at present?
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm of small round bars, commonly used as steel, bolts and various mechanical parts, larger than 25 millimeters of round steel, mainly for the manufacture of machinery parts. Round steel has many kinds of materials, such as: Q195, Q235, 10#, 20#, 35#, 45#, Q215, Q235, 304, 316, 20Cr, 40Cr, 20CrMo, 35CrMo, 20CrMnTi, 5CrMnMo, etc...
Round steel and thread steel are mainly made of different materials and purposes, so prices are different, and they need to be chosen according to actual needs.
Steel is known as hot rolled ribbed bar. The specification of rebar is large, and it belongs to small section steel. It is mainly used for the skeleton of reinforced concrete construction component. Generally required in the use of a certain mechanical strength, bending deformation properties and welding process performance.
