UNSPSC 31351501: Aluminum bolted tube assemblies

UNSPSC 31351501 Aluminum bolted tube assemblies is a Commodity code describing raw aluminum tubing and related metal components procured by state and local governments for facility maintenance, infrastructure projects, and operational needs. State and local buyers use this code narrowly: the Texas Department of Criminal Justice recently solicited raw aluminum tubing under IFB IW257847 (due July 24, 2026) without specifying gauge, alloy, diameter, wall thickness, or application in the available summary. The State of Maine Department of Administrative and Financial Services procured virgin aluminum substrate material (Alloy 3003-H12, Gauge 20 thickness) for reflectorized motor vehicle license plate manufacturing under RFQ #29B 26022400000000000207 (due April 3, 2026), with a total expected purchase of 70,000 pounds. These solicitations reveal that state procurement under this code targets raw or semi-finished aluminum stock for in-house manufacturing or maintenance operations rather than finished assemblies. Issuing bodies span state departments (Texas Department of Criminal Justice, Maine Department of Administrative and Financial Services) and specialized state agencies; the code does not show heavy activity from counties, cities, school districts, or transit authorities in the recent opportunities block.

Recent procurement activity concentrates in Texas and Maine, with the Texas TDCJ solicitation representing the most recent and straightforward aluminum tubing buy. The State of Maine's motor vehicle license plate material procurement reflects a specialized, high-volume use case with detailed material specifications including alloy composition, gauge, coating standards, and packaging requirements. Neither opportunity discloses a budget range or award value. The mismatch between the code's nominal name (bolted tube assemblies) and the actual solicitations (raw tubing and substrate material) suggests state and local procurement offices tag these raw-material buys under this Commodity code despite the absence of bolted assembly work in the available records. Activity remains sparse; the code does not show sustained multi-jurisdiction demand or frequent repeat buying cycles typical of high-velocity procurement categories.
