Sliding door rollers are typically located at the bottom of the door panel. These rollers allow the door to glide along the track, making it easy to open and close. Over time, dust and debris can accumulate in the track, or the rollers themselves may become worn, resulting in a door that sticks or will not slide properly.

Depending on the aspect of their application, their cross-sectional shapes can vary. Generally speaking there are four main cross-sectional shapes of fixed window profiles: flat, round, unequal polygon and equal polygon. Among them, the plane type is commonly used in door frames, wall corner lines, etc.; round profiles are mainly used for aluminum alloy pipes; unequal polygons and equal polygons are commonly used for window frames, partitions, etc.

Moreover, most metal storage boxes come with weatherproof coatings that help prevent any build-up of dirt or grime. This ease of maintenance allows you to spend more time enjoying your outdoor space rather than cleaning and caring for it.
