UNSPSC 31361300: Solvent welded plate assemblies

UNSPSC 31361300 Solvent welded plate assemblies (Class) covers structural steel components and assemblies that state and local governments procure for bridge construction, roadway infrastructure, and facility maintenance projects. Recent solicitations show heavy demand for W-beams, H-piles, and I-beams delivered to construction sites, with pricing typically accounting for 99 percent of evaluation weight and delivery included in unit cost on an F.O.B. destination basis. Issuing bodies are primarily county governments and state departments—Greenville County, South Carolina has posted multiple bids for structural steel in 2026, and the State of Illinois Department of Agriculture procured metal I-beams and plates for the State Fair Building and Grounds. Bidders are regularly required to submit references documenting similar work, evidence of manufacturer authorization or certification, and insurance documentation including general liability coverage of $1 million to $2 million.

Activity concentrates in South Carolina and Illinois, with Greenville County, South Carolina posting two major structural steel solicitations within weeks of each other in September and October 2026. Greenville County's IFB 27022 for W-beams (posted October 9, 2026, due October 9, 2026) sought four 27-inch beams at 114 pounds per foot and eight at 94 pounds per foot, all 27 feet in length, delivered to the Bridge Yard at 98 Camp Road, Travelers Rest; the county's earlier IFB 27014 for H-piles (due September 3, 2026) called for 24 H-piles in two configurations totaling 720 linear feet to the same delivery location. The State of Illinois Department of Agriculture issued a basic ordering agreement (posted April 27, 2026, due April 30, 2026) for eight I-beams at $375 per unit and two metal plates at $450 per unit, with total contract value of $3,900 and 30-day delivery windows. Performance and payment bonds, prevailing wage compliance, and firm pricing for 60–90 days are standard across solicitations. No recent opportunities show federal-aid roadway work under this specific code, though Broward County's Royal Palm Boulevard resurfacing project (due September 14, 2026) involved structural components but was tagged to a different UNSPSC classification.
