UNSPSC 31331705: Low alloy steel riveted structural assemblies

UNSPSC 31331705 Low alloy steel riveted structural assemblies, a Commodity code, covers custom metal fabrication and structural steel components that state and local governments procure for facility repairs, infrastructure projects, and maintenance operations. The actual work being solicited under this code includes fabrication of I-beams, metal plates, bridge structural components, and custom steel assemblies for protection and safety applications — ranging from small standardized purchases of metal stock to larger specialized fabrication contracts requiring welding, machining, and finishing capabilities. Issuing bodies span state departments of agriculture and transportation, cities, and county governments; purchases run from one-time small buys of basic materials through multi-year term contracts with renewal options. The mix reflects both routine maintenance procurement and project-specific infrastructure repair.

Recent opportunities cluster in the South and Mountain West regions, with documented activity in Texas, Illinois, Mississippi, Georgia, and Arizona. Representative solicitations include the State of Illinois Department of Agriculture's Basic Ordering Agreement (26406AGRBLDG4B52030, posted April 27, 2026) for eight 4-inch by 7.7-pound I-beams at $375.00 per unit and two 4-foot by 8-foot metal plates at $450.00 per unit, with a three-day response window and $3,900.00 total contract value; the City of Tucson's RFP for steel fabrication services (240080, posted March 26, 2026) requiring custom doors, railings, anti-vandalism covers, and mobile welding with a one-year initial term and four one-year renewal options and Section 3 labor hour requirements; the State of Georgia through Ware County's steel procurement (42000GFC0000445, posted February 12, 2026, due February 19, 2026) for the Georgia Forestry Commission shop with delivery required within four weeks; and the City of Philadelphia, Mississippi's sealed-bid Blount Street Bridge Repair project (3170035505, posted April 16, 2026, due April 23, 2026) encompassing timber pile repair, roadway approaches, and precast channel beam replacement.
