UNSPSC 31341700: Bolted sheet assemblies

UNSPSC 31341700 Bolted sheet assemblies, a Class code, covers structural steel components—primarily W-beams, H-piles, I-beams, and metal plates—that state and local governments procure for bridge construction, infrastructure repair, and facility maintenance. Recent solicitations show county transportation departments and state agencies buying these materials through firm-price, sealed-bid procurements weighted heavily on cost (99 percent) with minimal evaluation on responsiveness or technical factors. Issuing bodies include county transportation and engineering divisions, state departments of agriculture, and county purchasing offices. Deliveries are typically specified F.O.B. destination to a project site, with bidders required to provide delivery timelines from purchase order issuance, steel grade and ASTM designation documentation, performance and payment bonds, and general liability insurance ranging from $1 million to $2 million. Vendors must submit W-9 forms and at least three references demonstrating similar work experience, and contracts often incorporate 90-day project completion windows with liquidated damages for delays and ten percent payment withholding until satisfactory completion.

Recent activity concentrates in South Carolina and Florida, with Greenville County, South Carolina posting two IFBs in September and October 2026 for 24 H-piles (IFB27014, due September 3) and 12 W-beams (IFB27022, due October 9), both delivered to the Bridge Yard in Travelers Rest. Broward County, Florida solicited roadway resurfacing and infrastructure work (TRN2132636C1, due September 14) that includes structural components among broader highway construction scope, funded through FHWA and state surtax dollars. The State of Illinois Department of Agriculture procured I-beams and metal plates for the State Fair Building and Grounds (26406AGRBLDG4B52030, due April 30, 2026, $3,900 total value). All sealed-bid solicitations impose firm pricing on net-30 payment terms, F.O.B. destination delivery, and 60- to 90-day bid-acceptance windows. No pre-bid meetings are scheduled for the largest recent opportunities, though pre-bid conferences are held on larger, multi-scope infrastructure projects.
