How to choose aluminum alloy doors and windows correctly?

Aluminum alloy doors and windows are the first products to replace steel doors and windows. Aluminum alloy extruded profiles are used for frame, mullion and fan material. Aluminum sliding doors manufacturer produces ordinary aluminum alloy sliding doors and windows with aluminum alloy as the main material, sealing and sound insulation are better than steel windows, but also easier than  pure wood windows, steel door and window processing.


1. Look at the material

Aluminum alloy doors and windows of the main material generally includes three aspects: aluminum profiles, glass, hardware. The profiles used in high-quality aluminum alloy doors and windows are all exquisite: Only in terms of individual quality,tempered glass is better than ordinary glass. The hardware accessories of stainless steel (such as screws, hinges, hand and so on) are better than the aluminum accessories.

2. Look at processing

High-quality aluminum alloy doors and windows, fine processing, smooth tangent, the same angle, in the splicing process should not appear more obvious gaps, good sealing performance, smooth switch. Low quality aluminum alloy doors and windows, especially aluminum alloy outdoor doors and windows products if processing are not qualified, there will be sealing problems. Not only ventilation leakage and leakage of rain, but under strong winds and large external forces, the glass will burst and fall off.

3. Look at the appearance

There should be no obvious bruises, scratches, bumps or other defects on the surface of windows and doors. The coloring of adjacent members on doors and windows should not have a significant color difference. There should be no aluminum chips, burrs, oil spots or other stains on the surface of the window, and there should be no spilled adhesive at the assembly joints.

4. Look at performance

The performance of aluminum alloy doors and windows usually consider the following aspects: Strength, reflected in the selection of materials in the profile, whether can withstand ultra-high pressure. Airtightness is mainly reflected in the structure. Whether the internal fan and frame structure of doors and windows are tight, etc. Watertight, the main assessment of aluminum alloy doors and windows whether there is water, leakage phenomenon. Sound insulation, which mainly based on the sound insulation effect of hollow glass and other special sound-proof airtight structures and the durability of other window fittings  such as opening and closing force, opening and locking durability etc.

5. Look at the price

Under normal circumstances, the price of high-quality aluminum alloy is about 30% higher than that of inferior aluminum alloy doors and windows. Inferior aluminum alloy doors and windows are usually made of recycled aluminum extruded aluminum containing a lot of impurities. Use some aluminum wall thickness is not standard, and their tensile strength and yield are much lower than those of the state. This kind of aluminum alloy doors and windows, especially aluminum alloy outdoor doors and windows is very unsafe, so when purchase do not be greedy for cheap and neglect the personal safety of yourself and others.
