25MM Spring Roller Blind

1. Introduction to spring roller blinds

Spring roller blinds are named after the built-in spring device in the tube, also known as semi-automatic roller blinds. The sound insulation effect is good, and the connection between the roller blinds and the window is handled well, which can play a good sound insulation effect. Although it can't achieve 100% sound insulation, it can also solve many problems. From the perspective of solar shade, roller blinds are not as effective as heavy curtains.


2. Features of the product

1) The aluminum alloy upper beam is used as the support and positioning of the whole system, so that the installation and debugging are completed in the production plant to ensure the quality. Meanwhile, the on-site installation is very simple and convenient, and the operation is simple.

2) The damping device keeps the roller blind fabric at a slow and uniform speed during the process of retracting (rising), avoiding the impact of the traditional elastic roller shutter on the top of the window frame or the curtain box due to the excessively fast spring retraction speed.

3) The adjustable limit device can keep the spring roller blind away from automatically when it is retracted to the set position, ensuring that several roller blinds stop in a neat and uniform straight line when retracting the blind, and the intuitive effect is good. 

3. Product advantages

We adopts the hydraulic brake design. When the blind rises, the rebound speed slows down, and the lower rail gently leans against the roller blinds to avoid impact and reduce the noise during operation. It has a spring mechanism to control the automatic positioning mechanism and the self-locking function. Adjust the fabric to rise and fall within a certain range, and can be parked at any position. Pull down gently, and once you let go, the fabric can bounce back to the top of the curtain leisurely. The spring roller blind has a small and compact structure and is flexible and convenient to operate.
