A513-T1 HREW Round Tubing

Alro stocks mechanical low carbon steel tube, ASTM A513-Type 1 HREW Tube, in the as welded condition and furnished in grades 1008 to 1015. A513 tube is the lowest cost mechanical metal tubing available.  Wall thickness 18 gauge and lighter are produced from cold rolled steel. Heavier than 18 gauge is typically produced from hot rolled steel.  Welding is usually done as ERW, Electric Resistance Weld.  A513 Tube is typically available in hot rolled black or hot rolled P&O (Pickeled and Oiled).  Alro stocks HREW, which stands for hot rolled electric welded tube. A513 Type 1 has closer dimensional tolerance than A500 tube and A513 Type 1 allows bending.
