UNSPSC 31331700: Riveted structural assemblies

UNSPSC 31331700 Riveted structural assemblies, a Class code, encompasses the supply and delivery of structural steel components including W-beams, H-piles, and I-beams to support infrastructure construction and maintenance. State and local governments procure these materials primarily through county-level purchasing for bridge and roadway projects, with evaluation typically dominated by price (often 99 percent of the award criteria) and minimal weighting on responsiveness or technical factors. Issuing bodies include county transportation and highway departments, state departments of agriculture, and county purchasing offices. The scope of work reflects straightforward material procurement with firm pricing, F.O.B. destination delivery requirements, and net 30-day payment terms. Bidders generally must provide three references documenting similar supply work, carry comprehensive general liability and workers' compensation insurance, and submit W-9 forms and delivery timeline commitments.

Recent activity centers on South Carolina and Florida, with Greenville County, South Carolina emerging as a repeat buyer in the third quarter of 2026. Greenville County posted IFB 27022 for W-beams (four beams at 27 inches × 114 pounds per foot and eight beams at 27 inches × 94 pounds per foot, all 27 feet in length) with responses due October 9, 2026, and IFB 27014 for H-piles (12 each at 12 inches × 53 pounds per linear foot in 30-foot and 40-foot lengths) with responses due September 3, 2026. The State of Illinois Department of Agriculture issued a small purchase basic ordering agreement in April 2026 for I-beams and metal plates valued at $3,900.00. A Broward County, Florida roadway project (TRN2132636C1) posted in August 2026 with a September 14 bid deadline included structural work as a component of a larger $2.49 million federal and local-funded roadway widening and resurfacing effort. Activity shows modest recent volume concentrated in the Southeast, with most solicitations structured as straightforward competitive sealed-bid invitations with tight response windows of three to ten days.
