Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed as millimeters in diameter. For example, "50" means a round steel with a diameter of 50 millimetersRound bar is divided into three kinds of hot rolling, forging and cold drawing. The specification of hot rolled round bar is 5.5-250 millimeters. Among them, 5.5-25 rounds of small round bars are mostly supplied by straight strips. They are commonly used as reinforcing bars, bolts and various mechanical parts;
More than 25 mm round steel, mainly used in the manufacture of mechanical parts or between round steel and other steel seamless steel tube blank: 1 is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed. Bond thus causing steel and concrete, and the bond strength.2 other components of steel and concrete are not the same, round (a steel) belongs to the ordinary low carbon steel, alloy steel reinforced many other.3 strength is not the same. The low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other small steel however, plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
