What are the characteristics of aluminum alloy doors and windows?
1) light weight and high strength: aluminum alloy material is mostly hollow-core thin-walled combined section, which is convenient to use and reduces weight, and the section has high bending strength. The doors and windows made are durable and have little deformation.
2) good sealing performance: the aluminum alloy itself is easy to squeeze, the cross section size of the profile is accurate, and the processing accuracy is high. Optional waterproof, elastic and durable sealing materials, such as rubber layering and silicone series sealant. In terms of profiles, all kinds of sealing strip fixing grooves have been completed together with the same section in the extrusion molding process, creating favorable conditions for installing sealing materials.
3) beautiful appearance: after the aluminum alloy surface is anodized, it can present ancient lead liver copper, golden yellow, silver white and other colors, which can be selected at will, and is bright and shiny after oxidation. Casement large frame and insertable large area of glass make the indoor light bright and bright, enhance the contrast between the facade and the facade between indoor and outdoor, and make the room more layered.
4) strong corrosion resistance: the aluminum alloy oxide layer does not fade or fall off, does not need painting, is easy to maintain, and does not need maintenance.
Distinguish the advantages and disadvantages of aluminum alloy doors and windows:
look at the materials. Aluminum profiles used for high-quality aluminum alloy doors and windows, such as thickness, strength and oxide film, shall conform to relevant national standards and regulations. The wall thickness shall be above 1.2mm, and the tensile strength shall reach 157 newton per square meter, the yield strength should reach 108 newtons per square millimeter, and the thickness of oxide film should reach 10 micrometers. If it does not meet the above standards, it is inferior aluminum alloy doors and windows, which cannot be used.
Second, look at processing. High quality aluminum alloy doors and windows, finely processed, exquisite installation, good sealing performance, easy to switch. Inferior aluminum alloy doors and windows blindly choose aluminum profile series and specifications, rough processing, saw cutting instead of milling processing, do not install as required, poor sealing performance, not easy to switch, not only leakage of wind, leakage of rain and cracking of glass, but also encounter strong wind and external force, which makes it easy to scrape or knock off the push and pull part or glass, damaging things and hurting people.
Third, look at the price. Under normal circumstances, the price of high-quality aluminum alloy doors and windows is about 30% higher than that of inferior aluminum alloy doors and windows due to the high production cost. Some aluminum alloy doors and windows with a wall thickness of only 0.6-0.8mm are made of aluminum profiles, and the tensile strength and yield strength are much lower than the relevant national standards and regulations, so it is not safe to use. In addition, at present, there are many self-employed workers processing aluminum alloy doors and windows, and they do not know the structural characteristics and performance of aluminum alloy doors and windows. In order to reduce costs, cut corners and shoddy, the hidden danger of the product is relatively large, which is generally not suitable for use. It is best to choose the products of regular aluminum alloy doors and windows manufacturers.
