and conform to ASTM specifications A1008, A575, A576,
A635, or A36. The fitting steel also meets the physical
requirements of ASTM A1011 SS GR 33. The pickling of the
steel produces a smooth surface free from scale.
Many items are also available in stainless steel.
Consult factory for ordering information.
