UNSPSC 31231200: Machined plate stock

UNSPSC 31231200 Machined plate stock is a Class code under which state and local governments procure welding services, metal fabrication, and related repair work — not machined plate stock itself. The Hillsborough County Board of County Commissioners' recent mobile welding and fabrication services ITB illustrates the actual scope: on-site repairs to heavy equipment using shielded metal arc welding, gas metal arc welding, and gas tungsten arc welding, along with metal cutting, brazing, soldering, and component replacement. The work includes fabrication of roll-off containers, loaders, backhoes, excavators, and stationary cranes at solid waste management facilities. Issuing bodies under this code span county departments and special-purpose districts managing fleet maintenance and equipment repair operations.

The most recent activity appears concentrated in Florida. The Hillsborough County Board of County Commissioners issued ITB2600389 for mobile welding services on August 26, 2026, with bids due September 16, 2026; the three-year contract is estimated at $207,429.10 and requires four-hour response time during business hours and 24-hour emergency repair completion. Pricing is structured as unit rates across fifty-six line items covering journeyman and apprentice labor, emergency services, and materials including steel plates, channels, angle iron, tubing, and fabricated components. The contractor must carry $1 million Commercial General Liability, $1 million Automobile Liability, $1 million Professional Liability, and $1 million Cyber Liability, with Hillsborough County named as Additional Insured. A one-year warranty on all repairs and components is required. A second opportunity under this code — Texas Workforce Commission IW252223 posted June 24, 2026 — shows a mismatch: the notice purports to concern raw materials but actually describes IT infrastructure modernization and is unrelated to the code's nominal scope.
