Material: Rebars are usually made of carbon steel or low-alloy high-strength structural steel. Common materials include HRB335, HRB400 and HRB500.
Application: Rebars are widely used in concrete structures in construction projects, such as foundations, beams, columns, slabs, etc. They are used to enhance the tensile and bending strength of concrete and ensure the stability and safety of the structure.
Rebar is a long steel bar used in concrete structures, mainly to bear tension and provide structural strength. Rebar usually has good strength and toughness, and can form an effective mechanical connection in concrete. The surface of the rebar usually has spiral patterns to improve the bond with concrete. According to the standard, rebar can be divided into hot-rolled plain round rebar and hot-rolled ribbed rebar.
