Round refers to a circular cross section solid bar of steel. The specifications of a few millimeters in diameter, such as "50" means that 50 mm diameter round bar. Round into hot-rolled, cold-forging and drawing three. Hot rolled round steel specifications of 5.5-250 mm. Where: 5.5-25 mm small round mostly straight bundles of supplies, commonly used for steel, bolts and various mechanical parts; greater than 25 mm round steel, mainly for the manufacture of mechanical parts or seamless steel billet round the difference between steel and other steel: a different shape, round shape light circle, no pattern no ribs, other steel surface has a sculptured appearance or ribs, thus causing a small bar and concrete bond strength, The adhesion of other large steel and concrete. Two ingredients are not the same, round (a steel) belonging to the ordinary low-carbon steel, alloy steel, other steel mostly. 3 is not the same intensity, low round strength, high strength steel the other, that is the same size in diameter as compared with other steel round bar, round bar can withstand tensile steel than other small, round plastic but stronger than other steel that round before pulled off a larger deformation, while the other pulled off in front of steel deformation is much smaller. The difference with other steel round: 1 is not the same shape, round shape light circle, no pattern no ribs, other steel surface appearance has sculptured or ribs, thus causing a small bar and concrete adhesion while the adhesion of other large steel and concrete. Two ingredients are not the same, round (a steel) belonging to the ordinary low-carbon steel, alloy steel, other steel mostly. 3 is not the same intensity, low round strength, high strength steel the other, that is the same size in diameter as compared with other steel round bar, round bar can withstand tensile steel than other small, round plastic but stronger than other steel that round before pulled off a larger deformation, while the other pulled off in front of steel deformation is much smaller.
