Rolling Bifold and Walkthrough Doors

Grain doors hang with steel pegs

Schweiss Doors' grain and corn storage doors are constructed with 3/4-inch steel welded into the framework of 8-inch beams and use oversized pistons and a larger than standard hydraulic pump. To ensure zero leakage with several thousand pounds of grain against the doors, four 6-inch long steel pegs drop into the concrete footing at the bottom edge. Additionally, two steel pegs on each edge lock into the steel I-beam framework. Each hydraulic door can also have a steel slider door within it that lets the grain pour out for augering into feeding trucks.
