The frame of the high speed door refers to the structural frame of the door body, which is the main supporting part of the high speed door and is responsible for the installation of the door curtain and other components.

The following are several common fast door frame materials and their characteristics:

1. Steel frame: Steel frame is a common fast door frame material, usually made of high-quality cold-rolled steel plate. It has the characteristics of high strength and good rigidity, can provide a stable support structure, and is suitable for large industrial doors or places requiring higher security. The steel frame is anti-corrosion treated to increase its durability and rust resistance.

2. Aluminum alloy frame: Aluminum alloy frame is another common fast door frame material, which has light weight and excellent corrosion resistance. The aluminum alloy frame can provide stable support when used in the door structure, and has a good appearance effect. In addition, aluminum alloy has good thermal conductivity and is suitable for places that require thermal insulation or fire protection.

3. Stainless steel frame: The stainless steel frame has the characteristics of corrosion resistance, high temperature resistance and oxidation resistance, and is suitable for special environments or places with high hygiene requirements. The stainless steel frame can provide a stable support structure and is easy to clean and maintain. Common stainless steel materials include 304 stainless steel and 316 stainless steel.

The frame of the high speed door is usually made of high-strength materials to ensure the stability, durability and safety of the door body. Therefore, when choosing the material of the door frame, it is necessary to choose carefully according to the needs of the child in use.
