UNSPSC 31331300: Sonic welded structural assemblies

UNSPSC 31331300 Sonic welded structural assemblies, a Class code, covers the fabrication and delivery of structural steel components including W-beams, H-piles, I-beams, and metal plates for infrastructure and facility projects. State and local governments solicit these materials primarily through Invitations for Bid (IFB) and small-purchase agreements, with procurement driven by capital improvement programs in transportation, bridge construction, and facility maintenance. Evaluation typically weights price at 99 percent with minimal consideration for responsiveness, and bidders must provide firm pricing on an F.O.B. destination basis with delivery timelines and proof of capability through references. Issuing bodies include county transportation departments, state agricultural agencies, and county facility management offices; Greenville County, South Carolina has issued two separate solicitations for structural steel within the past two months, indicating active procurement in bridge-yard infrastructure projects.

Recent activity concentrates in the Southeast and South, with Greenville County (South Carolina) accounting for two of the three structural-steel opportunities posted since August 2026—IFB27022 for 12 W-beams totaling 114 and 94 pounds per foot, both 27 feet in length, due October 9, 2026, and IFB27014 for 24 H-piles in two configurations (12 and 40 feet, 53 pounds per linear foot each), with bids due September 3, 2026. Both Greenville County solicitations require delivery to the Bridge Yard at 98 Camp Road, Travelers Rest, South Carolina, payment of net 30 days, Performance and Payment Bonds, general liability insurance of $1 million per occurrence minimum, and submission of a County of Greenville Alternate W-9 Form with three references documenting similar work. The State of Illinois Department of Agriculture posted a small-purchase Basic Ordering Agreement (26406AGRBLDG4B52030) in April 2026 for eight 4-inch by 7.7-pound by 15-foot I-beams and two 4-foot by 8-foot metal plates totaling $3,900.00, with a three-day response window and 30-day delivery requirement. Geographic concentration remains limited to the Southeast and Illinois in the most recent pipeline, with no activity reported in the upper Midwest or Western states.
