UNSPSC 31331200: Bolted structural assemblies

UNSPSC 31331200 Bolted structural assemblies is a Class code covering the procurement of fabricated steel beam components — W-beams, H-piles, I-beams, and associated metal plates — that state and local governments buy for bridge construction, roadway projects, and facility maintenance. The recent opportunities show that county governments and state departments are the primary buyers under this code, with sealed-bid competitive procurement (IFB) as the dominant solicitation vehicle. Cost is weighted heavily in evaluation — typically 99 percent — with responsiveness and supplier references as secondary factors. Vendors must meet standard insurance requirements (general liability of $1 million per occurrence, workers' compensation), provide firm fixed pricing on an F.O.B. destination basis, and often supply performance and payment bonds. Delivery timelines from purchase order issuance and certification of steel grade and ASTM designation are routine submission requirements.

Recent activity clusters in South Carolina and Florida. Greenville County, South Carolina has issued two structural steel procurements in the past two months: IFB 27022 for W-beams (due October 9, 2026, sealed bids opened same day with anticipated award October 15) and IFB 27014 for H-piles (due September 3, 2026 with award scheduled September 8). Both sought delivery to the county's Bridge Yard at 98 Camp Road, Travelers Rest, and weighted evaluation 99 percent on price and 1 percent on responsiveness. Broward County Highway Construction and Engineering Division in Florida posted an RFB for Royal Palm Boulevard widening and resurfacing in Coral Springs (due September 14, 2026) with $2.492 million in total estimated cost, funded through Federal Highway Administration appropriations and county transportation surtax funds. A smaller procurement from the State of Illinois Department of Agriculture (posted April 27, 2026) sought I-beams and metal plates on a basic ordering agreement, indicating that the code also captures maintenance and repair work for state buildings and grounds. The dominance of bridge and roadway infrastructure in these opportunities signals that procurement under this code is tied to capital improvement cycles and state transportation budgets.
