UNSPSC 30104001: Round hollow structural section HSS

A circular hollow metal profile used in structural engineering

UNSPSC 30104001 Round hollow structural section HSS, a Commodity code, covers structural steel components and metal fabrication materials that state and local governments procure for facility construction, repair, and infrastructure projects. The code sees mixed activity across issuing bodies, with recent opportunities spanning state departments, cities, and special-purpose authorities; the solicitations show demand for steel beams, metal plates, and structural components used in building maintenance, bridge repair, and facility improvements rather than strictly hollow structural sections. The work ranges from small-quantity supply agreements for specific metals (such as I-beams and plates for state fairground buildings) to broader steel fabrication services contracts that include custom metalwork, welding, and protective infrastructure for municipal assets.

Recent opportunities are geographically dispersed. The State of Georgia (through Ware County) posted a steel procurement for the Georgia Forestry Commission on February 12, 2026, with a February 19 deadline; the State of Illinois Department of Agriculture solicited metal I-beams and plates for the Illinois State Fair Building and Grounds (IFB 26406AGRBLDG4B52030) on April 27, 2026, with a three-day turnaround to April 30 and a contract value of $3,900; the City of Tucson issued RFP 240080 for steel fabrication services supporting facility maintenance, including custom doors, railings, and anti-vandalism protection, with a pre-submittal meeting on November 16, 2023, and proposal due date of November 30, 2023; and the City of Philadelphia, Mississippi solicited bids for the Blount Street Bridge Repair project (IFB 3170035505) on April 16, 2026, with a April 23 deadline for timber pile repair and precast channel beam replacement. One Texas Workforce Commission procurement (IW252223) tagged to this code addresses IT infrastructure modernization and shows a mismatch with structural steel scope. The code demonstrates active state and local demand across supply-and-materials procurement and fabrication services, with response windows typically measured in days to weeks.
