Folding Doors

High clearance bi-fold doors for aircraft hangars, shops, warehouses, loading areas and farm buildings. You won’t go wrong with quality-built Bi-Folding Doors! They’re the only bi-fold doors with high-clearance advantages, requiring less overhead space. Made of heavy-duty steel tubing in sizes up to 70-feet wide and 20-feet high, their rugged, all-welded construction prepares them for many years of day-in and day-out use with minimum maintenance.
