Square & Rectangular Mechanical Steel Tubing.


L&R Industries fabricates square and rectangular, as-welded, mechanical steel tubing made from A513-T1, A513-T2 and ASTM A500, Grade B, carbon and alloy steels. Tubing is available in lengths from 24 inches, up to 45 feet with a current maximum diameter of 3”. With an extensive stock of common dimensions on hand, we cut lengths to order and usually ship with short lead times. For orders not in inventory, we regularly do line changeovers for made-to-order runs and provide quick turnarounds that meet your timeline and most challenging supply-chain demands.
