The industrial sectional door is composed of multiple door panels connected by hinges. A single door panel is usually 40mm thick. The material of the door panel is 0.45mm thick color steel plate baking paint. According to customer needs, aluminum alloy or 304 stainless steel can be customized. The height of a single door panel is 500mm. .

How does the industrial sectional door play the role of heat preservation?

1. The thickness of the door panel reaches 40mm, and the inside of the door panel is filled with high density polyurethane foam material, which can play a good role in heat preservation;

2. The sealing performance of the door is relatively good. The door panels are connected by hinges to make the door panels more tightly airtight. The top, bottom and both sides of the door are sealed and connected with EPDM strips, which effectively improves the sealing performance. Play the role of reducing air circulation, so as to better play the role of heat preservation.

Due to the large size of industrial sectional door, they are usually widely used as external doors of large factories, logistics garages, warehouse workshops and other places where it is inconvenient to install doors, and are more popular with customers in such occasions. And we usually don't recommend opening the lifting door frequently, usually about 10 to 20 times a day, and the time interval between the two times is preferably about 30 minutes.
