Nowadays, the home decoration of aluminum alloy doors and windows is a hot topic. At present, there are more and more brands of aluminum alloy doors and windows on the market, and the quality is uneven. Therefore, aluminum alloy doors and windows need to be carefully understood. I hope the following points will help you.

Selection skills of aluminum alloy door and window decoration;

1, see door and window product identification.

Regular or licensed production enterprises shall indicate product marks on the obvious parts of their aluminum alloy products, including the name or trademark of the production enterprise, product name, product model or mark, production date or number. There should be obvious words and signs such as "moistureproof", "handle with care" and "upward" on the packing box.

2. Look at the material of doors and windows

According to relevant national regulations, the wall thickness of aluminum profiles for aluminum alloy doors and windows should be no less than 1.2mm, and the thickness of oxide film should reach 10 micron. Therefore, the decoration of aluminum alloy doors and windows should choose high-quality products whose thickness, strength and oxide film can generally meet the national standards.

3. Look at the surface quality of doors and windows

The surface quality of aluminum alloy doors and windows directly affects the decorative effect of the whole wall after installation. Therefore, there should be no obvious damage to the decorative surfaces of aluminum alloy doors and windows, no obvious color difference, aluminium scrap, burr, oil stain or other stains on the colored surfaces of adjacent components, and no overflowing adhesive at the assembly joints.

4. Door and window glass

Windows and doors glass should be flat and firm, and there should be no looseness. Single-layer glass should not directly contact the profile, and the inner and outer surfaces of double-layer glass should be clean. There should be no dust and moisture in the glass interlayer and the gasket should not be inclined.

5. View door and window components

Aluminum alloy door and window components should be firmly connected, and the connection parts should be sealed and waterproof with corrosion-resistant filling materials.

6. Look at the sealing degree of doors and windows

The contact between aluminum alloy door and window sealing strip and glass and glass notch should be smooth, and curling or groove removal is not allowed. When the doors and windows are half open, there is no obvious gap between the sash and the frame, and the sealing strip on the sealing surface should be in a compressed state.

7, see the size deviation of doors and windows

The smaller the dimensional deviation of aluminum alloy door and window frames, the better.
