With the continuous expansion of the aluminum window and door market, many decoration and building materials companies choose to use aluminum window and door. The following briefly describes the issues that need to be paid attention to when purchasing aluminum window and door.
1. Identification of signs
Manufacturers with formal or production licenses will mark the product's logo on the obvious part of the aluminum alloy product, including: the manufacturer's name or trademark, product name, product model or mark, manufacturing date or serial number. There will be obvious words and signs of "moisture proof", "handle with care" and "upward" on the packing box.
2. Pay attention to the surface quality of doors and windows
The surface quality of aluminum window and door directly affects the decorative effect of the entire wall after installation. Therefore, when purchasing aluminum window and door, there should be no obvious damage on the surface, and the colored surface of adjacent components should not be obvious. Chromatic aberrations, aluminum chips, burrs, oil spots or other marks, there should be no spilled adhesive at the assembly connection.
3. Size deviation
The size of aluminum window and door frame is best to be the smallest deviation.
4. aluminum window and door components
The aluminum window and door components must be connected firmly, and corrosion-resistant filling materials must be used to seal and waterproof the connecting part.
5. Sealing degree of doors and windows
The contact between the aluminum window and door sealing strip and the glass and the glass notch should be smooth, and no crimping or bracketing is allowed. When the door and window are in the half-wall state, there is no obvious gap between the fan and the frame, and the sealing strip on the sealing surface should be in a compressed state.
