The roller blinds are blackout roller blinds, soft yarn roller blinds, and Shangri-La roller blinds in appearance. They are mainly corded and cordless. Roller shutters have many advantages such as beautiful and simple appearance, firm and durable structure, etc. Roller shutters are suitable for various places, especially for large-area glass curtain walls. When the roller blind fabric is put down, it can soften the indoor light, avoid the trouble of direct sunlight, and achieve a good shading effect. When the roller blind is raised, its volume is very small, so that it is not easy to be detected.
The bead roller blinds use the rope or chain to ascend and descend. The biggest problem of the rope/bead system is that the curtain will not be pulled when it is too big, and the rope will easily break. It is not very convenient to use, and the rope is easy to get dirty. It is very dangerous for children to play with ropes. In developed western countries, the use of beaded roller blinds has been banned and cordless curtains are fully used.
