Have a question about the item?
I purchased 2 sets of 5 row 12′ base (15′ bleacher) structures. What do I need for seating and floor (size and quantity)?
Hi Mark, we recommend 15’L x 10″W x 2″H seatboards and floorboards. You will need double footboards on the top two rows to meet IBC Codes for bleachers. Otherwise you will just need one seatboard and floorboard per row. Please let us know if you have any additional questions: 877-447-2648 or via email: support@graniteind.com. Thanks!
Can these understructures be used outdoors?
Hi Bill, yes these can be used outdoors. They are made of steel that has a long lasting powder coated finish.
