The materials and quality of aluminum doors and windows are the key factors that determine their performance and service life.

Material:

Aluminum alloy profiles: High-quality aluminum doors and windows usually use high-quality aluminum alloys, such as 6063 aluminum alloy. This alloy has good strength, corrosion resistance and machinability.

Insulation strips: The common insulation strip material is polyamide 66 (PA66), which has excellent high temperature resistance, low temperature resistance and aging resistance, can effectively block heat transfer and improve the thermal insulation effect of doors and windows.

Glass: Generally, hollow glass is used, which consists of two or more layers of glass and is filled with dry gas in the middle. High-quality aluminum doors and windows may use Low-E glass, which is coated with a low-radiation film on the surface, which can reflect far infrared rays and further enhance the insulation and energy-saving effects.

Hardware accessories: Including hinges, handles, locks, etc., high-quality hardware accessories are usually made of stainless steel or zinc alloy, which are durable, rust-proof and smooth to operate.

Quality:

Profile quality: The surface of high-quality aluminum alloy profiles should be smooth and flat, without obvious scratches, cracks and bubbles. The wall thickness of the profile should meet national standards to ensure the strength and stability of doors and windows.

Processing technology: Sophisticated processing technology can ensure that the size of doors and windows is high, the joints are flat and tight, and there are no obvious gaps and misalignments.

Glass quality: Good glass should be free of bubbles, inclusions and scratches. The sealing performance of hollow glass should be good, and the dry gas in the middle should not leak, otherwise it will affect the insulation and sound insulation effect of the glass.

Hardware accessories quality: High-quality hardware accessories are flexible to operate, the locks can firmly lock the doors and windows, and the handles and hinges and other parts will not loosen or jam during use.

Airtight and watertight performance: High-quality aluminum doors and windows should have good airtight and watertight performance when closed, and can effectively block the invasion of wind, rain and dust.

Wind pressure resistance: It can withstand a certain intensity of wind, is not easy to deform and damage, and ensures safety in severe weather conditions.
