Product Description

Bison Standard Aluminum Portable Outdoor Bleachers

The Bison Standard Aluminum Portable Outdoor Bleachers are rugged, weather-resistant seating systems designed for parks, fields, schools, and multi-sport facilities where reliable, portable spectator seating is needed. Built with premium aluminum and engineered for outdoor environments, these bleachers offer years of low-maintenance, trouble-free use.

Weather-Ready & Built to Last

These outdoor bleachers feature a 100% welded aluminum support structure that resists corrosion and rust, making them ideal for long-term outdoor use. Heavy-duty 2″ × 10″ anodized aluminum seat planks provide a comfortable, durable seating surface, and each plank includes end caps to eliminate sharp edges and enhance safety. 

Portable Design for Flexible Use

Bison’s portable bleachers include recycled plastic ground runners that raise the support framework above grass or dirt, protecting it from moisture and decay — and unlike wood runners used by some competitors, these won’t rot over time. 

Customizable & Easy to Specify

Available in multiple lengths (7½′, 15′, or 21′) and tier heights (2-tier, 3-tier, or 4-tier configurations), these bleachers can be matched to your crowd size and field layout. Note that 2-tier bleachers are only available in the 15′ length.
