TRUSS Floor System

Made from G90 galvanized metal, the “TRUSS” system gives you superior strength with minimal aeration loss. The “TRUSS” is able to withstand up to 100 feet of grain. With strength like that, the “TRUSS” floor is a must for bins over 30 feet high, and can be an option for smaller bins for farmers who want a stronger floor.

The floor support system offers quick connections and long spans means a fast and easy install. Engineered to aid in efficient airflow, the floor support system uses half the typical number of support rows.

After installation, the flooring simply lays flat on the support without having to snap in, allowing faster install, and accommodating uneven concrete floors. The support can also span in floor tunnels.
