UNSPSC 30104003: Rectangular hollow structural section HSS

A rectangular hollow metal profile used in structural engineering.

UNSPSC 30104003 Rectangular hollow structural section HSS (Commodity) covers structural steel components—I-beams, metal plates, and fabricated steel assemblies—that state and local governments procure for facility repair, infrastructure maintenance, and construction projects. Recent solicitations show state departments and municipal governments buying steel structural components both as raw materials for on-site use and as finished fabricated products through turnkey steel fabrication service contracts. The work ranges from small-purchase orders for specific beam and plate quantities to comprehensive steel fabrication agreements that include custom doors, railings, cages, and anti-vandalism protective structures. Issuing bodies include state departments (Texas Workforce Commission, Illinois Department of Agriculture, Georgia Forestry Commission) and city governments (Tucson, Philadelphia, Mississippi), with no dominant repeat buyer across recent postings.

Geographic activity spans Texas, Illinois, Georgia, Arizona, and Mississippi, with no clear concentration in any single region. Representative recent opportunities include the State of Illinois Department of Agriculture's Basic Ordering Agreement (IFB 26406AGRBLDG4B52030, posted April 27, 2026, response due April 30, 2026) for eight I-beams and two metal plates totaling $3,900 with 30-day delivery; the City of Tucson's Request for Proposal (RFP 240080, posted March 26, 2026) for comprehensive steel fabrication services including custom fabrication, welding, and mobile repair with Section 3 labor set-asides of 25 percent total hours and 5 percent targeted hours; and the State of Georgia's steel procurement through Ware County (IFB 42000GFC0000445, posted February 12, 2026, due February 19, 2026) for the Georgia Forestry Commission requiring four-week delivery of clean, rust-free steel quoted per foot, square foot, or piece. Delivery timelines typically range from four weeks to 30 days, and insurance requirements (where stated) include $1 million general commercial liability per occurrence.
