What are the basic principles for purchasing door and window profiles?

    Door and window profiles are the main raw materials for door and window manufacturing. The selection of door and window profiles is very important for the design, manufacturing and installation of doors and windows. It is related to the quality and service life of doors and windows. So, what are the basic principles for purchasing door and window profiles?

1. Application occasions and performance standards of doors and windows

Before purchasing door and window profiles, you need to determine the use occasions and performance standards of the doors and windows, including load-bearing capacity, heat insulation, waterproof and windproof, etc.

For example, doors and windows used in public buildings need to take into account their load-bearing capacity and anti-theft and fire protection capabilities.

The doors and windows in family homes must consider sound insulation, heat preservation, waterproofing and other properties.

2. Select the appropriate material

Door and window profiles currently mainly include aluminum alloy, UPVC, steel, wood and other materials.

Door and window profiles of different materials are different in terms of service life, price, thermal conductivity, etc.

Therefore, when purchasing door and window profiles, you need to choose the appropriate material based on the use needs, use environment and budget of the doors and windows.

3. Profile size and cross-sectional shape

The size and cross-sectional shape of the profile determine the load-bearing capacity and thermal insulation performance of the doors and windows. Generally speaking, the larger the cross-sectional shape of doors and windows, the better their wind resistance, earthquake resistance and thermal insulation performance.

In short, when purchasing door and window profiles, you need to comprehensively consider many aspects and choose the appropriate material, profile size and cross-sectional shape based on factors such as the use needs, use occasions and budget of doors and windows. Only by selecting appropriate door and window profiles can we ensure excellent door and window manufacturing and installation, making them more beautiful, practical and safe.
