Double-layer aluminum or steel polyurethane insulation door panels can reduce heat loss. For buildings that need insula-tion, they can realize heat preservation and energy saving. The 42mm thick door panel is ?lled with polyurethane foam materials (100% freon-free) from Bayer. The door panel is produced in a continuous production line backed by German technologies, and the high-pressure foaming process ensures that the polyurethane is ?lled evenly and satisfactorily.

High Strength Of Door Panel

The inner and outer metal panels are overlapped when the door panels are molded, which effectively prevents the door panels from being cracked, and the thickness of the four-layer hinge ensures the ?xing strength of the hinge screws.

Excellent Insulation Effect Of Composite Door Panel Design

Reliable Seal

With the bottom sealing strip, side sealing strip, top sealing strip and internal sealing strip between door panels, the sealing performance of the frame door reaches the highest level.

All seals except the internal inter-panel sealing strips are made of high quality EPDM sealing material.

Excellent Wind Resistant Performance

The special shape of the door panel and the design of the surface reinforcement ensure excellent wind resistant performance of the sectional door, which is sufficient to resist a Category 12 typhoon.

Doors with a width of 5,500mm or more can achieve sufficient wind resistant performance through the external reinforcement bar.

Diversified design can meet various needs in different occasions choosing different window and access mini door according to the design requirements
