UNSPSC 31331302: Carbon steel sonic welded structural assemblies

UNSPSC 31331302 Carbon steel sonic welded structural assemblies, a Commodity code, describes structural steel components including W-beams, H-piles, and I-beams that state and local governments procure for bridge construction, roadway infrastructure, and facility upgrades. Recent solicitations under this code show county and state entities buying fabricated steel structural members for delivery to specific project sites, with cost-driven evaluation and firm fixed pricing dominating the procurement approach. Greenville County, South Carolina has emerged as a repeat buyer, issuing multiple IFBs for structural steel members within the past six weeks. The work involves furnishing steel components to specification with F.O.B. destination delivery, standard performance and payment bonding, and compliance with insurance and reference documentation requirements typical of public construction procurement.

Activity under this code concentrates in South Carolina and Florida, with Greenville County posting back-to-back IFBs for structural steel—IFB 27022 for W-beams (12 beams totaling approximately 3,762 pounds of steel, due October 9, 2026) and IFB 27014 for H-piles (24 piles totaling approximately 38,160 pounds of steel, response deadline September 3, 2026, with pre-bid August 26). The Illinois Department of Agriculture posted a small purchase basic ordering agreement in April for I-beams and metal plates valued at $3,900. Broward County, Florida solicited roadway construction including structural work along Royal Palm Boulevard (bid due September 14, 2026), a $2.49 million project with FHWA and county funding. Evaluation under these IFBs heavily weights price (99 percent) with minimal points for responsiveness, and typical contract terms include 30-day payment, 60-day bid hold periods, and 90-day project completion windows with liquidated damages provisions of $250 per day. Contractors must provide proof of manufacturer authorization, hold $1 million general liability and auto liability coverage, and submit references documenting similar structural steel work.
