UNSPSC 30241603: Stringer

Tiered or stepped metal structures which act as the main support of a grandstand's structure on which one installs the seats, the footboards, etc.

UNSPSC 30241603 Stringer, a Commodity code, describes structural metal framing components used in bleacher and grandstand construction. State and local governments procure stringers—the angled support beams and structural members that form the risers and seating framework—as part of fabricated bleacher systems and stadium seating installations. Issuing bodies include school districts (the dominant purchaser tier), community colleges, county boards of supervisors, and municipalities, with recent activity concentrated among Georgia, Michigan, and Mississippi public bodies. The work solicited under this code spans turnkey bleacher fabrication and installation, maintenance and inspection services, and temporary seating deployments at athletic facilities. School districts dominate the buyer base, typically issuing sealed IFBs or RFPs for fixed gymnasium bleacher systems, outdoor baseball and softball seating, and stadium grandstands; colleges and counties pursue larger stadium renovation or new-construction projects at lower frequency. Evaluation typically emphasizes compliance with ICC 300 Standard for Bleachers, ADA accessibility, Georgia/Michigan/Mississippi Building Code alignment, warranty terms, and installation experience on K-12 projects.

Recent solicitations show sustained demand for both new fabrication and replacement installations. Fulton County Schools (Georgia) issued multiple IFBs and RFPs for terrace seating upgrades at Chattahoochee High School (due dates spanning September through November 2026), with mandatory pre-bid conferences and site visits. Emanuel County Schools solicited sealed proposals for demolition and installation of motorized telescoping gymnasium bleachers at Swainsboro Middle School (RFP due July 17, 2026), requiring factory-trained installers and three K-12 references. Hancock County School District (Mississippi) requested sealed bids for two telescopic bleacher units with all-inclusive turnkey pricing at Hancock North Central Elementary (bids due June 23, 2026). Northview Public Schools (Michigan) issued RFPs for stadium addition and renovation including bleachers and associated work as a multi-phase bid package (responses due September 21, 2026). Cherokee County School District (Georgia) solicited annual inspection and maintenance services for bleachers and basketball goals district-wide (RFP due September 3, 2026), indicating demand for ongoing maintenance contracts. TIPS USA posted a statewide cooperative purchasing vehicle for auditorium, stadium, field seating, bleachers, and installation services on a Job Order Contract basis (proposals due September 18, 2026), available to multiple Texas public entities. Geographic activity clusters in Georgia (Fulton, Emanuel, Cherokee counties), Mississippi (Hancock, Harrison, Lafayette, Tunica counties), and Michigan (Northview, Grosse Ile districts), with additional activity in Texas through cooperative purchasing. Bid security requirements typically run 5 percent of bid amount; contract awards favor lowest responsive, responsible bidders with demonstrated K-12 experience, ICC 300 compliance, and warranty commitments.
