The difference between round steel and other rebar
1, the appearance is not the same, the round steel appearance is round, no lines and no ribs, and the surface appearance of other steel bars is engraved or ribbed, so that the bond between round steel and concrete is small, and the bond between other steel bars and concrete is large.
2, the composition is not the same, round steel (first grade steel) belongs to ordinary low carbon steel, other steel bars are mostly alloy steel.
3, the strength is not the same, the strength of round steel is low, and the strength of other steel is high, that is, compared with other steel bars of the same diameter, the tension that round steel can withstand is smaller than other steel bars, but the plasticity of round steel is stronger than other steel bars, that is, the round steel has a larger deformation before being pulled off, and the deformation of other steel bars before being pulled off is much smaller.
