These bleachers have a capacity of 70. Portable bleachers are available with welded steel frames (hot dipped galvanized after fabrication) and welded aluminum frames. The planking is extruded aluminum 2' x 10' 6063-T6 anodized finish for seats and mill finish for foot boards. Standard guardrails are made of vertical 1/2' rod welded to 1 5/8' top and bottom rails to assure that a 4' sphere will not pass between them. Please note: In many areas of the country, there are local building codes which require the use of guardrails along with extra footboards and risers on rows higher than 30'. Please check your local codes to determine if guardrail assemblies are required in your community. Please note that this is a freight item and can not be expedited.
