Always consult your lead structural engineer before substituting grades, as the elongation and bend test requirements vary between Japanese and American standards.

The standard is essential for:

JIS G 3112 governs both and deformed steel bars manufactured through hot rolling. Deformed bars, often identified by symbols like SD 295 , SD 345 , and SD 490 , feature surface protrusions or "knots" designed to increase the frictional bond between the steel and the surrounding concrete. These classifications are not arbitrary; they represent specific yield points and tensile strengths. For instance, SD 490 indicates a higher yield point requirement (minimum 490 jis g3112 pdf
