Transparent Window
The uniquely sized 600 × 300 mm windows enhance indoor brightness and provide clear visibility between inside and outside areas. Crafted from high-strength acrylic panels, they offer long-lasting durability and crystal-clear transparency.
Coating Process
A Dacromet coating can be applied to the torsion spring, creating a durable anti-corrosion layer that isolates the surface from air exposure, effectively extending the spring’s lifespan and resistance to harsh environments.
Paint Material
In high-humidity conditions, a baking varnish coating is recommended over the standard galvanized finish to enhance corrosion resistance and ensure consistent door operation.
Small Door
The door-in-door system features an interlock mechanism that prevents the main door from opening unless the smaller access door is fully closed, ensuring safe operation.

Four Main Lift Types For Sectional Roller Door
Standard Lift
The most common type, used when sufficient standard headroom is available above the door opening. Most of the door rests horizontally under the ceiling when open.
High Lift
Used when there is ample headroom. The door travels vertically higher before turning horizontally, maximizing clear space above the opening when the door is up.
Vertical Lift
Requires very high headroom (at least the door height plus clearance). The door travels straight up vertically, resting directly above the opening when fully open.
Low Headroom Lift
Specifically designed for installations with extremely limited headroom. Often uses special tracks (like a double-track system) and rear-mounted torsion springs to minimize the required overhead space.
