UNSPSC 40181806: Welded steel tube assembly

Welded tube assembly made of steel

UNSPSC 40181806 Welded steel tube assembly is a Commodity code that state and local governments source for infrastructure rehabilitation and construction projects involving structural support components, traffic management systems, and safety barriers. The Santa Clara County Central Expressway Pavement Rehabilitation Project illustrates the practical scope: welded steel tube assemblies function as components within guardrail systems, traffic signal structures, bioretention basin supports, and related roadway infrastructure rather than as standalone products. State and local issuing bodies acquiring under this code span counties, cities, and transportation authorities pursuing road, highway, and transit facility improvements. The work involves specification of welded steel tube assemblies as part of broader capital projects where materials and assembly quality directly affect safety and durability in outdoor, high-traffic environments.

Santa Clara County issued an IFB (ITBRDAFY260694) on April 29, 2026, for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, with bids due May 21, 2026. The project scope encompasses pavement rehabilitation, guardrail system replacement and installation, traffic signal modifications, and pedestrian infrastructure improvements over a 142-working-day performance period. The solicitation seeks qualified contractors to supply labor, materials, and equipment; welded steel tube assemblies appear as specified components within the Midwest Guardrail System removal and replacement and traffic signal support work. California represents the most recent documented geographic activity under this code.
