What is Oversized HSS Tubing?

Oversized HSS Tubing is large steel tubing designed to meet the demand for large loading requirements or long spans.  Under the ASTM designation of A1065, Oversized HSS Tubing is fabricated up to 1” wall thickness, and is available in both Grade 50, and Grade 50W.  H.W. Metal Products, Inc. Oversized HSS Tubing is manufactured by a multiple step process.  Material is cut to size on one of our plasma tables (up to 100’ in length) and formed into matching C-Channels on our 60’ x 2500 ton CNC press brake.  The C-channels are carefully fitted into place with the support of a backing bar.  The two sections are then submerged arc welded along the longitudinal seams.  Throughout this process, H.W. Metals takes extreme care to meet all required dimensional tolerances, as well as a minimum standard of 80% weld penetration (PJP).  – 100% weld penetration (CJP) is available upon request with independent Ultrasonic Testing provided.
