1.Cold room door overhead door or called sectional door 
2.Good insulation
3.Polyurethane foam panel with anti-pinch design
4.K = 0,338 W / sqm° C
Overhead door is designed for wind proof, heat insulation and the installation of the limited space industrial workshop, design for closed platform and cold storage of the door.
Overhead door has good tensile and puncture resistance property. It is suitable for use in frequent opening places. The highest speed reaches 0.6-1.0m/s. It applies to pharmaceutical, food and electronic industries and some other factory buildings or isolation areas, which requires high cleaning level. It has advantages in good performance, high tensile, safety, low noise, fine sealing, good thermal insulation properties, space saving and increasing productivity. Thus, it is widely used for its low installation conditions and high practicability.
