UNSPSC 30241604: Stair riser

Vertical structural element covering the space between two steps in a staircase.

UNSPSC 30241604 Stair riser (Commodity) covers bleacher and stadium seating systems that state and local governments procure for athletic facilities, gymnasiums, and outdoor field venues. Recent activity shows school districts and county educational agencies purchasing complete bleacher installations—including demolition of existing systems, supply of new seating units with structural components (risers, treads, railings, decking), and turnkey labor and installation—rather than stair risers in isolation. The code captures bleacher procurement at the component level, though buyers typically solicit full systems with integrated riser assemblies. School districts dominate this market segment, appearing in nearly every recent opportunity; county boards of supervisors and higher-education athletic departments also issue bleacher procurements. Georgia school districts (Fulton County Schools, Emanuel County Schools, Cherokee County School District) appear as repeat buyers with multiple 2026 solicitations.

Recent activity spans four U.S. regions. Georgia leads with five distinct opportunities: Fulton County Schools issued overlapping IFBs and RFPs for terrace seating at Chattahoochee High School (due November 12, 2026 and October 22, 2026) and Emanuel County Schools solicited motorized telescoping gymnasium bleachers at Swainsboro Middle School (due July 17, 2026). Michigan shows two stadium-renovation efforts—Northview Public Schools' athletic stadium addition and renovation including bleachers (due September 21, 2026) and Grosse Ile Township Schools' theater fixed seating (due June 1, 2026). Mississippi has concentrated activity with Northwest Mississippi Community College (pre-bid September 10, 2026, bids due September 24, 2026), Hancock County School District (bids due June 23, 2026), and Lafayette County School District (bids due August 20, 2026). Texas solicitations include a statewide cooperative purchasing vehicle through TIPS USA for auditorium and stadium seating with installation (due September 18, 2026) and the University of Texas at Austin's temporary bleacher rental and installation at UFCU Disch-Falk Field (due May 6, 2026). Bleacher inspection and maintenance services also appear—Cherokee County School District's RFP for annual bleacher and basketball goal inspection and maintenance (due September 3, 2026) represents recurring service revenue beyond initial installation.
