Alro stocks mechanical carbon tubing, ASTM A513-Type 2 CREW tube, in cold rolled electric welded condition and furnished in steel grades 1008 to 1015. A513 is the lowest cost mechanical tubing available; it is formed from hot rolled strip steel and then cold reduced. This process creates tighter tolerances and improved surface over Type 1. Alro stocks A513-T2 CREW (Cold Rolled Electric Resistance Welded).
ASTM A513-Type 2 is typically selected when exposed surfaces require a good cosmetic appearance. A513-Type is typically available in round as well as square tube.
