Steel Rebar Product Information
Steel rebar is a ribbed steel bar on the surface,also known as ribbed steel bar,usually with two longitudinal ribs and transverse ribs evenly distributed along the length.The shape of the transverse ribs is spiral,herringbone, and crescent.It is expressed in millimeters of the nominal diameter.
The shape of the transverse ribs is spiral, herringbone,and crescent. It is expressed in millimeters of the nominal diameter.The nominal diameter of ribbed steel bars is equivalent to the nominal diameter of smooth round steel bars with equal cross-sections.The nominal diameter of the steel bars is 8-50 mm,and the recommended diameters are 8,12,16,20,25,32,and 40 mm.Ribbed steel bars mainly bear tensile stress in concrete. Ribbed steel bars have greater bonding capacity with concrete due to the action of ribs,so they can better withstand external forces.Ribbed steel bars are widely used in various building structures,especially large,heavy,light thin-walled and high-rise building structures.
Steel Rebar Usage And Advantage
Usage:
Steel rebar is widely used in civil engineering construction such as houses,bridges and roads.As large as public facilities such as highways, railways, bridges, culverts, tunnels, flood control, dams, etc., as small as foundations, beams, columns, walls, and panels of house construction, rebar is an indispensable structural material.
Advantage:
Concrete has a very high compression strength,but relatively low tensile and torsional strength.While helping to prevent the formation and spread of cracks that could destroy the whole project.In addition,steel is the best material for rebar use because of its similar thermal expansion properties to concrete,avoiding many issues relating to temperature change.
