Use expansion screws or chemical bolts and other fixings to firmly fix the door frame to the wall. The spacing of the screws should be evenly distributed, and generally a fixing point should be set every 300-500 mm. Ensure that the installation depth and strength of the fixings meet the requirements to withstand the weight of the door body and the tension during operation.
Install the guide rail: The guide rail should be installed parallel and straight, and the distance between the two guide rails should match the width of the door body. Use a tape measure and a level to measure and adjust to ensure the installation accuracy of the guide rail. The connection between the guide rail and the door frame should be firm and reliable, and should be connected by welding or bolting. When welding, ensure the quality of the weld, without defects such as pores and slag inclusions; when bolting, tighten the nuts to prevent loosening.
Install the door body: Install the door body of the aluminum alloy rolling shutter door on the guide rail to ensure that the door body runs smoothly in the guide rail. The curtain blades of the door body should be arranged neatly without dislocation or distortion. During the installation process, lubricating oil can be applied appropriately to reduce the friction between the door body and the guide rail. Connect the door body and the motor to ensure that the transmission device of the motor is firmly connected to the reel of the door body. The installation position of the motor should be reasonable for easy maintenance and operation, and the appropriate wire specifications should be selected according to the power of the motor and the weight of the door body to ensure stable power supply.
Electrical device installation: If the rolling door is equipped with an electric drive device, the electrical safety specifications must be strictly followed during the installation process to ensure that the circuit connection is correct and reliable to avoid electrical fires or electric shock accidents. At the same time, safety protection devices such as limit switches and anti-pinch devices should be set according to actual conditions to ensure the safety of users during use. The installation of the motor should be carried out in accordance with the product manual. Note that the motor should be firmly fixed and the wires should be arranged reasonably to avoid affecting the normal operation of the door body.
Debugging and operation: After the installation is completed, the rolling door is debugged and operated. Check whether the functions of the door body such as rising, falling, and stopping are normal and whether the operating speed is moderate. The operating speed of the door body can be controlled by adjusting the parameters of the motor. The general rising speed is 0.2-0.5 meters per second and the descending speed is 0.3-0.8 meters per second. Test the door’s rebound function when encountering obstacles to ensure that it can automatically stop and reverse when encountering obstacles. The sensitivity of rebound when encountering obstacles should be moderate. At the same time, check whether the operation of the remote control is sensitive and reliable. The effective distance of the remote control should meet the requirements, generally within the range of 30-50 meters, and ensure that the password of the remote control is set securely to prevent malicious operation by others.

3. Debugging and maintenance after installation
Comprehensive inspection: After the installation is completed, conduct a comprehensive inspection of the entire rolling door system to check whether each component is firmly installed, whether the screws are loose, whether the curtain blades are tightly installed, whether the guide rails are straight, etc., to ensure that all components are in good working condition.
Performance test: Perform multiple door opening and closing tests to observe the stability, smoothness and noise level of the rolling door during operation. Check the sealing performance of the rolling door to ensure that it can fit tightly with the door frame in the closed state to achieve a good sealing effect, and play a role in anti-theft, windproof, and soundproofing.
Lubrication and maintenance: Regularly clean and lubricate the shutter door’s curtain blades, guide rails, bearings and other components. You can use an appropriate amount of lubricating oil or grease to reduce friction between components and extend the service life of the shutter door. At the same time, check the operation of the motor and regularly maintain the motor, such as cleaning the motor surface, checking the heat dissipation of the motor, replacing worn parts, etc., to ensure the normal operation of the motor.
Regular maintenance: Develop a regular maintenance plan, regularly check the various components of the shutter door, and promptly discover and solve potential problems. For example, check whether the screws are loose and tighten them in time, check whether the curtain blades are deformed or damaged and repair or replace them to ensure that the shutter door always maintains good performance.

4. Safety precautions
Professional installation: The installation of the shutter door requires certain professional knowledge and skills. It is recommended to choose a professional installer or team to install it to ensure the installation quality and safety of use.
