Installation Instructions
Installation Measurement Parameters
All measurements are made indoors and each value must be measured at at least three points:
H - the height of the door opening (the distance from the ground to the top of the door opening)
B - the width of the door opening (the distance from the left edge of the door opening to the right edge)
h - at least 500 mm above the door opening (the distance from the top of the door opening to the ceiling)
b1/b2 - requires a lateral distance of at least 150 mm left and right (distance from the corresponding edge of the door opening to the obstacle)
L - is the depth of the room
• When measuring H and B, take the maximum value as the final size.
• When measuring h, b1, b2 and L, take the smallest value as the final size.

Q What safety mechanisms are built into the sectional door system?

The door system includes multiple built-in safety features such as a torsion spring fracture protection device, a wire rope break protection device, end buffers, and a heavy-duty reinforced door structure to prevent accidents and ensure uninterrupted operation.

Q How are the installation dimensions measured correctly?

All measurements must be conducted indoors across at least three distinct points. When determining opening height (H) and width (B), take the maximum measured value. When calculating headroom (h ≥ 500 mm), side room (b1/b2 ≥ 150 mm), and room depth (L), select the minimum measured value.

Q How does the sectional door ensure thermal insulation?

High thermal efficiency is maintained through insulated sandwich door panels combined with a comprehensive multi-point sealing system, including top, bottom, and side sealing profiles that effectively isolate indoor room temperatures.
