Sectional Overhead Door for Metal Processing Plants
In metal processing plants, doors must handle heavy-duty operation, large openings, and frequent forklift traffic. Our Industrial Lift-up Door / Sectional Overhead Door is designed specifically for demanding industrial environments, offering reliable performance, excellent sealing, and flexible configuration for steel and aluminum processing facilities.
What Is a Sectional Overhead Door?
Definition & Basic Structure
A Sectional Overhead Door, also known as an Industrial Sectional Door or Factory Lift-up Door, consists of multiple horizontal panels connected by hinges. The door moves vertically along reinforced tracks and rests parallel to the ceiling when fully open, maximizing usable space inside metal processing plants.
How a Sectional Overhead Door Works
The door operates through a track system with torsion springs or extension springs, balancing the door weight for smooth lifting. It can be configured as a Manual Sectional Door or Automatic Sectional Overhead Door, depending on usage frequency and operational requirements.
