Brief Introduction
The door panel move up during opening and eventually fully enter the overhead room along the tracks. The door panel does not fold or roll during opening. There are 3 types of overhead sectional doors according to the move direction.
The door panel moves along the horizontal tracks during opening, which is suitable for the door openings with small overhead room.
The door panel moves along the vertical tracks during opening, which is suitable for the door openings with enough overhead room.
The door panel moves upward along the vertical tracks for a while, and then moves horizontally, which is suitable for the door openings with big overhead room.
Configuration and Work Principle
The door comprises 5 parts: 1) door system; 2) track system; 3) torsion spring balancing system; 4) sealing system; 5) door opener system.
Material
The surface panel is color steel and polyurethane composite board, with wrinkle/smooth surface upon request. The panel pressing shape could be in square, deep channel or shallow channel. The tracks are rolled from thick galvanized steel board. Sealing strip will be in EPDM rubber.
