NIGP 57083: Structural Shapes, Other Than Steel: Angles, Channels, I-Beams, etc.

NIGP 57083 Structural Shapes, Other Than Steel: Angles, Channels, I-Beams, Etc., Item code, covers non-ferrous and composite structural framing materials state and local governments procure for construction projects. Recent activity shows state and local agencies soliciting these materials primarily as line items embedded in larger construction contracts rather than as standalone commodities. The City of San Antonio Capital Delivery Department's Hays Street Bridge Connections & Eastside Area Streets project (RFCSP2026025, RFP due August 25, 2026) and Fire Station #33 Facility Replacement (RFCSP2026071, RFP due July 30, 2026) both identify structural shapes among applicable NIGP categories. Sarasota County's Midnight Pass Road Pedestrian Bridge (262861MN, IFB due July 20, 2026) specifies a steel truss bridge deck with prestressed concrete piles and concrete end bents. The City of Scottsdale's Westworld Bahia Drive Drainage Improvements (26IFB063, IFB due April 29, 2026) lists drainage and concrete structures as scope elements. Issuing bodies include city capital delivery departments, county governments, and municipal utilities managing infrastructure projects funded through local bonds and federal transit administration grants.

Geographic activity concentrates in Texas (San Antonio appears twice), Florida (Sarasota County), and Arizona (Scottsdale), with scattered activity in Massachusetts, Wisconsin, and Utah. Representative recent opportunities are heavily weighted toward municipal and county construction projects rather than standalone structural-material procurement, suggesting that vendors pursuing this code should position themselves as subcontractors or material suppliers embedded in general contractor teams on infrastructure projects. The code sees limited independent RFQ or IFB activity; most sourcing occurs within competitive sealed proposal cycles for concrete and structural work on public facilities and transit improvements. Massachusetts State Housing Authority's window replacement and floor finish projects (posted February through May 2026) show some direct procurement of building components but do not reference this NIGP code explicitly.
