In many building materials, aluminum alloy doors and windows must be used in home decoration, and there are many types and brands of products. How can consumers choose the right aluminum alloy? In the face of wave after wave of promotion bombs in the major building materials market, how to select a high-quality and low-cost aluminum alloy product has become the focus of many people's attention.
1、 Look at the appearance
The surface quality of aluminum alloy doors and windows will directly affect the overall effect after installation. When selecting, attention should be paid to: the decorative surface of doors and windows should not have obvious damage and scratch, the protective film on the surface should not be scratched; the adjacent components on the doors and windows should not have obvious color difference, otherwise the surface aesthetics of aluminum alloy doors and windows will be affected; Aluminum chips, burrs, oil spots and stains should not appear on the surface of aluminum alloy doors and windows. The aluminum alloy is connected and combined by screws and screws. After installation, the aluminum alloy surface should not expose too many nail holes.
2、 Look at the material
The main materials used for aluminum alloy windows generally include three aspects: aluminum profiles, glass and hardware. The wall thickness of aluminum profiles used for high-quality aluminum alloy windows should meet the specifications, and the thickness of oxide film should reach the specified thickness; tempered glass is better than ordinary glass; and stainless steel hardware accessories (such as screws, hinges, handles, etc.) are better than aluminum accessories. The Xinyi Glass is used for the doors and windows of columbi, which is the highest level of toughened glass in the world. According to the standard calculation, there is no difference! 30 grains / 1C m2, high toughness, strong bearing capacity and high safety!
3、 Look at processing
High quality aluminum alloy window, fine processing, smooth tangent, consistent angle (the main frame material is usually 45 degrees or 90 degrees), in the splicing process should not appear obvious gap, good sealing performance, smooth switch. Poor quality aluminum alloy window, especially aluminum alloy outdoor window products, if the processing is not qualified, there will be sealing property problems, not only air and rain leakage, but also under the action of strong wind and large external force, the glass will burst and fall off. All products of keleni doors and windows adopt 30 years service life as the design standard, and the processing technology has passed the ISO2000 quality system certification.
