1. Door panel
PU sandwich panel, Available thickness: 75mm, 100mm,150mm and 200mm. PU density: 40kg/m³, with good heat preservation. Surface material is painted galvanized steel or 304 stainless steel, with thickness of 0.5mm.
2. Guide rail:

Top guide rail is made from aluminum alloy. Multi-bearing design divides the door weight and makes the door works more smoothly and durable.
3. Heater
There is a low voltage electric heater around the door leaf to prevent the door and frame from freezing at low temperatures.
4. Safety lock design
It can be used to open the door from inside easily and quickly in emergency cases, to protect human life.
5. Sealing structure
EPDM seal rubber is paved between guide rails and door, and between door and wall, to make the structure much more air tight and heat-preserving.

6. Curve track design with great sealing performance

The top track is a curve form. When the door is closed, the door leaf automatically presses the floor and the door frame, with good sealing performance is guaranteed. When opened, the door leaf leaves the door frame and rises, reducing the friction between the sealing rubber strip and the door frame and floor.
