1. Overview of Fast Doors: High speed rolling shutter doors, also known as fast rolling shutter doors, have multiple functions such as thermal insulation, cold insulation, insect prevention, wind prevention, dust prevention, sound insulation, fire prevention, odor prevention, and lighting. They are widely used in various places such as food, chemistry, textiles, electronics, supermarkets, freezing, logistics, and warehousing, and can meet the requirements of high-performance logistics and clean places. They also save energy, automatically close at high speed, improve work efficiency, and create a better working environment
