UNSPSC 31331105: Low alloy steel bonded structural assemblies

UNSPSC 31331105 Low alloy steel bonded structural assemblies, a Commodity code, covers the supply of fabricated structural steel components—W-beams, H-piles, and I-beams—that state and local governments procure for bridge construction, roadway infrastructure, and building projects. Recent state and local solicitations show counties and state agencies buying these materials in standardized sizes and quantities, with delivery on a firm fixed-price, F.O.B. destination basis. Work under this code involves furnishing steel components that meet specified ASTM designations and grades, with suppliers responsible for transportation to the project site. Issuing bodies include county transportation and engineering divisions and state departments; Greenville County, South Carolina appears as a repeat buyer, having posted two separate IFBs for structural steel within six weeks.

Recent activity concentrates in South Carolina and Florida. Greenville County issued IFB 27022 (W-Beams) with a response date of October 9, 2026, calling for four W-beams at 27 inches, 114 pounds per foot, and eight at 27 inches, 94 pounds per foot, all 27 feet in length, delivered to the Bridge Yard in Travelers Rest. The county also issued IFB 27014 (H-Piles) in September 2026 for 24 H-piles in two configurations (12 and 12 each at 12 inches, 53 pounds per linear foot, in 30-foot and 40-foot lengths). The State of Illinois Department of Agriculture posted a basic ordering agreement (26406AGRBLDG4B52030) in April 2026 for I-beams and metal plates totaling $3,900. In all three structural steel opportunities, cost evaluation dominates at 99 percent, with responsiveness weighting at 1 percent. Suppliers must provide references, comply with insurance requirements (general liability of $1 million per occurrence minimum), submit W-9 forms, and in bridge work cases, post performance and payment bonds. Delivery timelines and firm pricing are standard contract requirements.
