Steel Construction
There are two key components to an understructure; frames and cross braces. Granite has taken time to ensure each of these components are properly engineered and constructed. The frames are built from A500 steel, which is known for its superior strength characteristics. The frames are then powder coated by hand through Granite’s state of the art Wagner system. The cross braces are built from galvanized steel. Mounted with premium steel hardware these components combine together to create an incredibly solid bleacher understructure.

Customization
The understructures come in different lengths and different row amounts. This allows for the exact bleacher setup to fit your specific event or venue. Add your own seat boards, foot boards, and toe boards as you see fit.
