The aluminum alloy sliding doors have an upper pulley and a lower pulley, respectively. The upper slide plays a guiding role because it is mounted on the upper track, and the consumer often does not pay attention to it when selecting and purchasing. The DER Building aluminum slider door has a relatively complicated sliding structure, which is not only compact, but also the door and window anti-swing positioning wheel makes the door and window slide smoothly in the upward direction, effectively preventing the door and window from stopping when pushing and pulling. And the pulling force is large, and has strong wind pressure resistance, almost no noise. Consumers should not mistake the sliding door for slippery. In fact, high quality sliding doors should have a certain degree of self-weight, smoothness and no vibration when sliding. The rationality of the ground rail design directly affects the comfort and service life of the product. Consumers should choose a foot that feels good and contributes to a clean and hygienic style. At the same time, DER Building doors and windows remind you that the height of the ground track should not exceed 5mm for the safety of the elderly and children at home.

In addition to the use of transparent glass in sanitary doors, glass sliding doors are the majority, and the quality of the glass directly determines the price of the door. The roof of the sky is made of standard hollow tempered glass, which is harmless to the human body and has a high safety factor. And has excellent sound insulation and thermal insulation properties.
