In many cases, when the aluminium profile of doors and windows is deformed and repeatedly pressed, it is found that the maximum wind pressure is seriously inconsistent with the design requirements. The reason is that the wall thickness is not fully considered when selecting the aluminium profiles for door and window. In general, the determination of the wall thickness is combined with the characteristics of the section of the profile, and there is no uniform standard. In general, thin-walled aluminium profiles are not accepted in window and door fabrication. The force-receiving members of the aluminum doors and windows include the frame, the upper glide path, the window fan material, etc. The actual measured dimensions of the minimum wall thickness of these stressed members shall be not less than 1.4 mm for the outer window and not less than 2.0 mm for the outer door. The detection method uses a vernier caliper to perform on-site random sampling inspection of the aluminium profile.
Once the door is removed, inspect the rollers. Look for signs of wear and tear, such as cracks, warping, or broken parts. If the rollers appear damaged, they will need to be replaced. If they are simply dirty or misaligned, a good cleaning or adjustment may suffice.

These profiles are desgined for windows that open outwards or inwards via hinges. They are usually used in residential homes due to their ease of operation and good sealing.


2. Lubrication Apply a suitable lubricant to the rollers and tracks periodically. This will reduce friction and ensure smooth operation. Avoid using sticky lubricants that can attract dirt and grime.
As sustainability becomes a priority for many homeowners, cast iron fencing presents an eco-friendly option. Cast iron is a recyclable material, and modern production techniques often emphasize reducing waste and energy consumption. By choosing cast iron, homeowners contribute to environmental conservation efforts while enjoying the benefits of a long-lasting product.
