Currently, several quality certifications are widely recognized in the wire and cable industry. These include the Quality Management System Certification, Environmental Protection Certification, Occupational Health and Safety Certification, Production License, CCC Mandatory Certification, Coal Mine Safety Certification, CQC Voluntary Certification, CRCC Railway Certification, PCCC Electrical Energy Certification, Postal and Telecommunications Network Card, Ministry of Radio and Television Network Access Certificate, and the Ministry of Public Security Fire Certification. It's worth noting that some of these certificates may not be universally recognized across different provinces and municipalities.
In addition to these, there are other important certifications such as Classification Society Certifications, Export Licenses, State Grid Communications Network Access License, and Specialized Cables Production Licenses for Nuclear Power Plants. These certifications ensure that products meet strict safety, environmental, and performance standards, especially for critical infrastructure and high-risk applications.
Each certification serves a specific purpose, whether it's ensuring compliance with national regulations, meeting international trade requirements, or adhering to industry-specific safety standards. As the wire and cable industry continues to evolve, the importance of these certifications is likely to grow, especially with increasing emphasis on sustainability, safety, and quality control.

The service life of aluminum sliding windows is affected by many factors:
1. Material quality
Aluminum alloy profiles
If high-quality aluminum alloy profiles are used, the wall thickness meets the standard and the alloy composition is excellent, its service life can reach 30-50 years or even longer. For example, some high-quality aluminum alloy profiles such as 6063-T5 have strong corrosion resistance and deformation resistance.
Hardware accessories
Hardware accessories such as pulleys, handles, locks, etc. have a greater impact on the overall life. Good quality stainless steel or copper hardware accessories can be used for 10-20 years under normal use. Cheap and low-quality hardware may be damaged in 5-10 years, such as pulley wear leading to poor sliding and pulling.
2. Use environment
Climatic conditions
In dry and mild climates, aluminum sliding windows have a longer service life. However, if they are located in coastal areas, high humidity and high salt air will accelerate the corrosion of aluminum alloys, which may shorten the service life to about 20-30 years; in areas with more acid rain, it will also cause erosion on its surface.
Daily maintenance
Regular cleaning, maintenance, and timely replacement of aging parts of aluminum sliding windows will greatly extend their service life. On the contrary, if there is a long-term lack of maintenance, the life of the window may be reduced by 5-10 years.
