When installing a rolling door, how do you ensure the door is level?

In the process of installing the rolling door, ensuring the levelness of the door is a very important step. It not only affects the appearance of the rolling door, but also affects the performance and life of the door. The following are some key steps and methods to ensure the levelness of the rolling door during installation.

1. Preparation
Before installing the rolling door, you need to make adequate preparations, including measuring the size of the installation location and ensuring that the size of the rolling door matches the door opening.

In addition, you need to check whether the pre-buried lines of the rolling door are in place, and whether the position and number of the pre-buried parts meet the design requirements.

2. Line positioning
In the preliminary stage of installing the rolling door, you need to use a level tester to determine the position of the slides on both sides of the door frame and ensure that they are level. Determine the position of the guide rail and the scroll by using the line, which is the basis for ensuring the levelness.

3. Fix the guide rail
The installation of the guide rail is the key to ensuring the levelness of the rolling door. Use screws to fix the guide rail above the installation location and ensure that the guide rail is flat and firm. If the verticality of the wall where the guide rail is installed does not meet the requirements, shims must be added to adjust the verticality before welding.

4. Install the reel
The installation of the reel also requires precise horizontal control. The reel should be connected to the curtain plate and fixed to the guide rail with screws. At the same time, pay attention to adjust the position and tightness of the reel to ensure its levelness.

5. Adjust the door curtain
Insert the door curtain of the rolling door into the guide rail and gradually unfold it to ensure that the door curtain is installed flat and not skewed. During the installation of the door curtain, it is necessary to constantly adjust to ensure the horizontality of the door curtain.

6. Calibrate with a level and a plumb gauge
During the installation process, it is very important to calibrate with a level and a plumb gauge. These tools can help installers accurately adjust the position of the rolling door to ensure its horizontality and verticality.

7. Debugging and testing
After installation, debug and test the rolling door to ensure the flatness of the door. During the debugging process, observe the contact condition between the drum body, curtain plate, guide rail and transmission part and the symmetry of the active gap, and make necessary adjustments until the lifting is smooth and the force is even.

8. Quality inspection
Finally, the installation quality of the rolling door needs to be checked, including whether the variety, type, specification, size, opening direction, installation position and anti-corrosion treatment of the rolling door meet the design requirements. Check whether the installation of the rolling door is firm, and whether the number, position, embedding method and connection method of the embedded parts meet the design requirements.

Through the above steps, it can be ensured that the rolling door reaches the required level during the installation process, thereby ensuring its normal operation and service life. Correct installation and adjustment are the key to ensuring the performance of the rolling door, so it must be carried out in strict accordance with the installation standards and process requirements.
