Product introduction
Rebar execution standard: ASTM A615/A615M.
Steel number: Gr40.
In the case of export, the available range of ASTM A615 grade 40 rebar cut length will be in the range of 6-12m.
American standard rebar is divided into Gr40 (280MPa grade steel rebar) and Gr60 (420MPa grade steel rebar) according to the strength grade.
ASTM A615 Grade 40 rebar is a surface-ribbed steel bar that is primarily subjected to tensile stress in concrete.
Grade 40 rebar is widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures.
