ATP manufactures all of HHS products to ASTM A500 Grade B. Much of ATP’s square and rectangle tubing also satisfies Grade C requirements. Most of ATP’s round tubing meets ASTM A53 Grade B (non-hydro) standards.

All squares, rectangles, and rounds are stenciled A500-B. Upon request, ATP can re-certify material to an alternative grade or specification (A500 Grade C, or A53-B non-hydro) , provided that the material satisfies the new standard.
