Rebar is a ribbed steel bar produced by a small rolling mill; Iron ore hot coil is a strip steel made of slab heated by roughing mill and finishing mill.

2, use the difference:

Steel bars are widely used in civil engineering construction such as houses, bridges and roads. Iron ore hot coils are widely used in shipbuilding, automobiles, bridges, construction, machinery, pressure vessels and other manufacturing industries.

3, classification differences:

Steel bars are divided into three grades: Grade II HRB335, Grade III HRB400 and Grade IV HRB500. Iron ore hot coil is divided into ordinary carbon structural steel, low alloy steel and alloy steel.

4. Different specifications:

Rebar is a ribbed steel bar on the surface, also known as ribbed steel bar. It usually has two longitudinal ribs and transverse ribs, which are evenly distributed along the length direction. The shapes of transverse ribs are spiral, herringbone and crescent. Expressed in millimeters of nominal diameter. The nominal diameter of reinforcement is 8-50mm, and the recommended diameters are 8, 12, 16, 20, 25, 32 and 40 mm..
