UNSPSC 31341400: Sonic welded sheet assemblies

UNSPSC 31341400 Sonic welded sheet assemblies is a Class code that covers structural steel components—primarily W-beams, H-piles, and I-beams—that state and local governments procure for bridge construction, highway infrastructure projects, and facility maintenance. Recent solicitations show counties and state departments buying these components through formal sealed-bid competitions weighted heavily on price, with delivery to specific project sites and firm pricing based on net 30-day payment terms. Issuing bodies include county transportation and capital-improvement offices, state departments of agriculture, and highway construction divisions. The code sees activity from both major metro counties and mid-sized rural jurisdictions, each procuring steel components for distinct infrastructure initiatives.

Greenville County, South Carolina dominates the recent opportunity set, having posted two sealed-bid solicitations within six weeks: IFB27022 for W-beams (posted October 9, 2026, due October 9) and IFB27014 for H-piles (posted September 21, 2026, due September 3). Both required F.O.B. destination delivery to the county's Bridge Yard in Travelers Rest and mandated performance bonds, comprehensive general liability insurance ($1 million per occurrence / $2 million aggregate), and references documenting similar work. Greenville's evaluation weighting was 99 percent price and 1 percent responsiveness in both cases. Outside South Carolina, the State of Illinois Department of Agriculture issued a small-purchase basic ordering agreement (26406AGRBLDG4B52030, posted April 27, 2026, due April 30) for I-beams and metal plates totaling $3,900.00. Activity clusters in the Southeast and Midwest, with procurement emphasis on firm unit pricing, F.O.B. destination terms, and strict delivery timelines tied to construction schedules.
