UNSPSC 30101513: Tin angles

UNSPSC 30101513 Tin angles, a Commodity code, nominally covers structural tin angle stock, but recent state and local solicitations show minimal activity directly aligned with tin angles as a discrete product. Instead, the code appears in procurement records for large construction projects where structural materials including angles are components of broader scope — civil infrastructure, bridge construction, and facility replacement work. State and local governments buying under this code include municipal capital delivery departments and county governments, principally issuing competitive sealed proposals and invitations for bids for design-build or turnkey construction contracts. The issuing bodies treat tin angles as a subordinate line item or specification within larger construction packages rather than as a standalone commodity procurement.

Recent opportunities show activity in Texas and Florida. The City of San Antonio Capital Delivery Department posted two major construction RFPs in mid-2026: the Hays Street Bridge Connections & Eastside Area Streets project (RFCSP2026025, due August 25, 2026) and Fire Station #33 Facility Replacement (RFCSP2026071, due July 30, 2026), both funded through 2022 Bond programs and listing structural shapes among applicable product categories. Sarasota County solicited construction bids for the Midnight Pass Road Pedestrian Bridge (IFB 262861MN, due July 20, 2026), a steel truss pedestrian bridge incorporating structural elements. One outlier appears in the University of Wisconsin-Madison's metals procurement RFB (2026-UWMSN-01207-RFB, due April 20, 2026), which requests steel, aluminum, and stainless steel materials in general, without specific structural component detail. The code shows limited independent procurement velocity; vendors should expect tin angles to be sourced as specification components within general construction contracts rather than as direct-purchase commodity opportunities.
