As the technical content and the degree of mechanization of doors and windows are not high, most of them rely mostly on the manual operation of the installation workers, which requires the operators to have a good sense of product quality. It is important to strengthen the proficiency of the operators and their product awareness during the production process. High-quality aluminium windows should acquire the following qualities: fine processing, consistent angle (the main frame is usually 45 or 90 degrees), no obvious gaps during the splicing process, good sealing performance and smooth operation.

caster wheels for sliding doors. They come in a variety of sizes and styles to suit different types of doors and tracks. Whether you have a traditional wooden sliding door or a modern glass door, there are caster wheels available to fit your specific needs.
4. Energy Efficiency Modern slimline aluminium profiles can be designed with thermal breaks, which significantly improve their insulation properties. This means that buildings can achieve higher energy efficiency, leading to lower heating and cooling costs. In an era where sustainability is paramount, this feature makes slimline profiles an excellent choice for environmentally conscious construction.
1. Cleaning Dust and debris can accumulate in the window tracks, hampering the smooth movement of the rollers. Regularly clean the tracks with a soft brush or cloth, ensuring that there is no obstruction.
If an aluminium frame is dented or badly scratched, the only solution is to replace it with a new one, which unfortunately involves very high costs. The situation is different with wooden windows, where small scratches can often be repaired, while dents are very rare.
