UNSPSC 31331205: Low alloy steel bolted structural assemblies

UNSPSC 31331205 Low alloy steel bolted structural assemblies is a Commodity code encompassing fabricated structural steel components — primarily W-beams, H-piles, and I-beams — that state and local governments procure for bridge construction, roadway infrastructure, and building projects. The recent opportunities show county transportation and state facility departments purchasing finished structural members in standard grades, with delivery to job sites and cost as the dominant evaluation criterion. Work under this code centers on supplying dimensionally specified steel sections with documented ASTM grades and delivery timelines, often paired with bonding and liability insurance requirements typical of public construction supply contracts.

Greenville County, South Carolina has emerged as the most active buyer in the recent window, issuing two competitive sealed bids for structural steel within six weeks — IFB27022 for W-beams due October 9, 2026, and IFB27014 for H-piles due September 3, 2026 — both targeting bridge yard deliveries with 99-percent cost weighting and firm 30-day pricing. The State of Illinois Department of Agriculture posted a small-purchase Basic Ordering Agreement (26406AGRBLDG4B52030) on April 27, 2026 for I-beams and metal plates to support State Fair Building and Grounds work, with a total contract value of $3,900. Geographic activity concentrates in South Carolina and Illinois within the recent six-month window, with no standout repeat buyers beyond Greenville County's two back-to-back solicitations. Evaluation criteria uniformly emphasize price dominance, with responsiveness and delivery capability as secondary factors; bidders must provide three references documenting similar work, current insurance certifications, and W-9 documentation. Performance bonds equal to total contract price are routinely required within fifteen business days of award.
