A square hollow metal profile used in structural engineering

UNSPSC 30104002 Square hollow structural section HSS is a Commodity code covering structural steel components and related materials that state and local governments purchase for infrastructure repair, maintenance, and construction projects. Recent solicitations show state and local buyers procuring structural steel shapes — including W-beams, H-piles, and I-beams — for bridge work, roadway projects, and facility maintenance. The Greenville County, South Carolina procurement opportunities illustrate the typical buying pattern: sealed bids on structural steel delivered to specific job sites under firm, fixed pricing with cost dominating evaluation. Issuing bodies include county transportation and infrastructure divisions as the primary buyers under this code.

Recent activity clusters in South Carolina and Florida. Greenville County has posted two concurrent IFBs for structural steel — IFB27022 for W-beams (sealed bids due October 9, 2026) and IFB27014 for H-piles (bids due September 3, 2026, with a non-mandatory pre-bid meeting on August 26) — both for bridge yard delivery with 99 percent price weighting and 1 percent responsiveness evaluation. The Illinois Department of Agriculture solicited I-beams and metal plates under a small-purchase basic ordering agreement (due April 30, 2026, total value $3,900). A Broward County roadway construction project (TRN2132636C1, due September 14, 2026) includes structural components as part of a broader infrastructure contract. Greenville County's back-to-back solicitations signal ongoing bridge maintenance or replacement work; both require Performance and Payment Bonds, delivery timelines from purchase order issuance, and F.O.B. destination pricing inclusive of freight.
