This guide summarizes regular-schedule and on-demand production capability for hollow structural sections (HSS) produced by the nine STI member producers — Atlas Tube, Bull Moose Tube, H.W. Metals, Maruichi American (MAC), Maruichi Leavitt, Maruichi Oregon (MOST), Nucor Tubular, Searing Industries, and Vest — across over 20 facilities, representing the majority of the domestic market. For current real-time availability across producers, use the STI Capability Tool.
Scope of this guide: the tables in this guide cover ASTM A500, which is commonly produced on a regular rolling schedule. ASTM A1085's size availability largely mirrors A500's but is produced on demand only; ASTM A1065 is also on demand.
| Grade | Description | Minimum yield, Fy | Wall thickness | Size range | Availability |
|---|---|---|---|---|---|
| ASTM A500 | Cold-formed carbon steel structural tubing — typically roll-formed from coil and joined by electric-resistance welding (ERW); seamless is also permitted by the spec. The most widely specified HSS standard for general structural use. Grade C (Fy = 50 ksi) is the recommended default. | 50 ksi (Grade C) | Up to 1″ | Max perimeter = 88 ″ per spec | Produced Regularly see tables on following pages |
| ASTM A1085 | Cold-formed welded carbon steel HSS, manufactured like A500 but with tighter wall thickness and corner radii tolerances plus an added minimum mass tolerance. The tighter wall thickness tolerance lets designers use the full nominal wall thickness (no 0.93 reduction). Includes a Charpy V-notch (CVN) requirement. | 50 ksi | 0.148″ to 1″ | Similar to A500; max perimeter = 88″ | Produced on Demand |
| ASTM A1065 | Cold-formed HSS that extends beyond A500's size range for square and rectangular sections. Each tube is press-brake-formed from two C-shape plate halves and joined by submerged-arc welds (SAW) along two seams. Typically specified for tall columns, long spans, and heavily-loaded members. Grades 50 and 50W (weathering). | 50 ksi | Up to 1″ | Square up to 50″×50″; rectangular up to 60″×40″; round not offered. Max perimeter = 200″. | Produced on Demand |
On the producer's published rolling schedule. Standard sizes are typically maintained in distributor inventory and can be filled within normal lead times.
The producer has the equipment and tooling to manufacture this size but does not run it on a recurring cycle. Expect extended lead times, minimum order quantities, and potential tooling setup fees.
