A500 Grade A B C ERW Tubes
A500 Grade A B C Welded Pipe Supplier-GNEE
ASTM A500 Structural Tubing is a standard specification for cold-formed welded structural tubing produced in round nominal sizes. ASTM A500 is the most common specification for hollow structural sections in North America. Because ASTM A500 is a structural specification, round tubular HSS produced to this specification is suitable for structural applications and general construction use.
