UNSPSC 31331302: Carbon steel sonic welded structural assemblies

UNSPSC 31331302 Carbon steel sonic welded structural assemblies, a Commodity code, describes custom metal structural fabrication and component supply work that state and local governments procure for facility repair, infrastructure projects, and asset protection. Recent solicitations show state and local buyers purchasing I-beams, metal plates, custom steel doors, railings, anti-vandalism protection boxes, bridge components, and general steel stock for maintenance and construction needs. The issuing bodies span state departments (Illinois Department of Agriculture, Georgia Forestry Commission through Ware County), municipalities (City of Tucson, City of Philadelphia Mississippi), and single-purpose state agencies. The work typically requires vendors to be established manufacturers or authorized dealers with metal fabrication, welding, machining, and finishing capabilities across carbon steel, stainless steel, galvanized steel, and coated materials.

Recent activity concentrates in the Southwest and Southeast. The City of Tucson issued an RFP (No. 240080) in March 2026 for comprehensive steel fabrication services including custom doors, cages, anti-vandalism boxes, and hand railings, with a one-year initial term and up to four one-year extension options; that procurement carried Section 3 worker requirements (25% of labor hours by Section 3 Workers, 5% by Targeted Section 3 Workers) and DBE compliance obligations. The State of Illinois Department of Agriculture posted a basic ordering agreement (No. 26406AGRBLDG4B52030) in April 2026 for I-beams and metal plates totaling $3,900.00 with a three-day response window. The City of Philadelphia, Mississippi solicited sealed bids (No. 3170035505) in April 2026 for bridge repair including precast channel beam replacement. The State of Georgia through Ware County posted a steel bid (No. 42000GFC0000445) in February 2026 for Georgia Forestry Commission shop material with a four-week delivery requirement.
