Application range

The application of round steel has broad prospects. It is widely used in hardware, construction, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace, construction and decoration. The most common parts of ordinary machinery processing, the general rod steel, CD rod, bolts, nuts.

Product advantages

The difference between round bars and other bars:

1, the appearance is not the same, round shape round, non-textured ribbed, the other surface of the steel profile or ribbed.This will result in a small bar and concrete bond strength, and other steel and concrete Strong bond.

2, the composition is not the same, round steel (a steel) are ordinary mild steel, mostly steel and other steel.

3, the strength is not the same. Low strength round steel, high strength of other steels, that is the same diameter of the round bar Compared with other bars, round bar can withstand the pull less than other bars, but round plasticity than other bars Strong, that is, the round bar is pulled off before the larger deformation, while the other before being pulled off the deformation is much smaller.
