UNSPSC 31331502: Carbon steel solvent welded structural assemblies

UNSPSC 31331502 Carbon steel solvent welded structural assemblies is a Commodity code covering structural steel components—primarily W-beams, H-piles, and I-beams—that state and local governments procure for bridge construction, roadway infrastructure, and facility maintenance projects. Recent solicitations show county and state transportation authorities buying fabricated steel members in discrete quantities, with pricing and delivery timelines as the dominant evaluation factors. The work involves supply of mill-certified steel structural shapes meeting ASTM specifications, with F.O.B. destination delivery and firm pricing on net 30-day terms. Issuing bodies include county transportation and public works departments (Greenville County, South Carolina; Broward County, Florida) and state agencies (Illinois Department of Agriculture). Cost typically dominates evaluation at 99 percent, with responsiveness to specifications or technical compliance weighted at 1 percent.

Greenville County, South Carolina has been the primary recent buyer, posting two separate IFBs for structural steel within the past month: IFB27022 for twelve W-beams (four at 27 inches, 114 pounds per foot, 27 feet long, and eight at 27 inches, 94 pounds per foot, 27 feet long) with a due date of October 9, 2026, and IFB27014 for twenty-four H-piles (twelve at 12 inches, 53 pounds per linear foot, 30 feet long, and twelve at 40 feet long) with a due date of September 3, 2026. Both required electronic submission, firm pricing, and delivery to the Bridge Yard in Travelers Rest, South Carolina. Illinois Department of Agriculture posted a small-purchase Basic Ordering Agreement for eight 4-inch by 7.7-pound by 15-foot I-beams and two metal plates with a total contract value of $3,900.00 (due date April 30, 2026). A Broward County IFB for Royal Palm Boulevard roadway improvements (posted August 12, 2026, due September 14, 2026) included mast arm installation and structural work but was primarily a comprehensive transportation project. The code shows intermittent but steady activity in the Southeast and Midwest, concentrated in infrastructure maintenance and expansion work.
