UNSPSC 31361600: Sonic welded plate assemblies

UNSPSC 31361600 Sonic welded plate assemblies, a Class code, covers structural steel components including W-beams, H-piles, and I-beams that state and local governments procure for bridge, roadway, and building projects. Recent solicitations show counties and state agencies buying finished structural steel stock in standardized sizes and lengths, delivered to project sites on a cost-plus-freight basis with minimal value-add fabrication. The work is straightforward materials supply for construction projects — counties source beams and piles for bridge yard inventory and infrastructure widening, while state departments and school facilities request plates and I-beams for maintenance and repair.

Greenville County, South Carolina has been the most active issuer under this code in the recent record, posting two separate IFBs in September and October 2026 for H-piles and W-beams destined for a Bridge Yard in Travelers Rest. The county weights price at 99 percent in both solicitations, requires F.O.B. destination delivery, three references documenting similar work, and performance bonds equal to contract value. The Greenville County IFB27014 for H-piles closed September 3, 2026, while the later IFB27022 for W-beams closed October 9, 2026. The State of Illinois Department of Agriculture also posted a small Basic Ordering Agreement for I-beams and metal plates in April 2026, with a three-day response window and a total contract value of $3,900. South Carolina and Illinois show activity under the code; a broader geographic characterization is not supported by the source.
