UNSPSC 31361600: Sonic welded plate assemblies

UNSPSC 31361600 Sonic welded plate assemblies is a Class code that encompasses metal structural components, raw steel materials, and custom steel fabrication services procured by state and local jurisdictions for facility maintenance, infrastructure repair, and asset protection. State and local buyers under this code range from state departments and county governments to city utilities and special-purpose facilities. The scope of work includes supply of structural steel components (I-beams, metal plates), raw metal materials for shop operations, and custom steel fabrication services covering doors, railings, protective enclosures, welding repairs, and specialized metal finishing across steel, galvanized steel, stainless steel, and aluminum.

Recent activity spans Texas, Illinois, Mississippi, Arizona, and Georgia. The State of Illinois Department of Agriculture solicited a Basic Ordering Agreement (BOA) in April 2026 for I-beams and metal plates with a total contract value of $3,900.00 and a three-day response window. The City of Tucson issued RFP 240080 for steel fabrication services including custom doors, anti-vandalism boxes, railings, and emergency welding, with Section 3 Program requirements mandating 25% of labor hours from Section 3 Workers and initial one-year term with four optional one-year extensions. The State of Georgia, through Ware County, posted an IFB on February 12, 2026 with a February 19 deadline for steel procurement to the Georgia Forestry Commission shop, requiring delivery within four weeks of award with all material to arrive clean, oil-free, and rust-free. The City of Philadelphia, Mississippi solicited sealed bids for the Blount Street Bridge Repair project with deadline April 23, 2026, encompassing timber pile repair, roadway approach repair, and replacement of precast channel beams. Opportunities under this code show tight response windows (three to seven days typical) and modest to moderate contract values in the low-thousands to mid-five-figure range.
