One, materials
The aluminum doors and windows material generally consists of three aspects: aluminum, glass, metal pieces, and the owners in the purchase of products, often pay more attention to the thickness of the aluminum and glass, and the hardware requirements are not very high, it is not comprehensive. In fact, the state of aluminum alloys doors and windows of the requirements of a certain standard. Aluminum alloy doors and windows of high quality aluminum profile, the film thickness, strength and generally in line with national standards, such as the relevant provisions of the state requirements: aluminum alloy doors and windows aluminum wall thickness should be in no less than 1.2mm and oxide film thickness should be up to 10 microns. While the glass than ordinary glass is better, if the consideration to the safety and durability of the doors and windows, stainless steel hardware accessories (such as screw, hinge, handle and so on) to better than aluminum parts, the best choice and pulley using POM material products, because such products have higher strength and wear resistance, the use of in the process of smooth, is not easy to bad.
Two, processing
Have a good material; the next step is the processing of the doors and windows. Due to the aluminum alloy doors and windows of the technical content is not high, mechanization level is not high, majority is also dependent on the installation workers, manual operation, which requires the operator to have good awareness of product quality. It is important to strengthen the operator's proficiency and product awareness in the production process. High quality aluminum alloy doors and windows, processing fine, smooth tangent, consistent point of view (main frame material usually is a 45 degrees or 90 degrees), in the process of stitching should does not appear obvious gap, good sealing performance, smooth switch. Inferior aluminum alloy doors and windows, especially aluminum outdoor window products if the processing is not qualified, will lead to seal the nature of the problem, not only air leaks and under the effect of strong winds and large external force, the glass will appear crack, fall off phenomenon, resulting in to the owners of property loss even wounding phenomenon.
Three, appearance
Owners buy aluminum alloy doors and windows products, usually pay much attention to the appearance and the products of glass decorative pattern, and often belittles the surface of aluminum alloy doors and windows of the composite membrane and the composite membrane is formed by artificial coloring, corrosion resistance, wear resistance, high gloss. At the same time, also has a certain fire prevention function, so in the purchase of aluminum alloy doors and windows products to multiple comparisons of similar products. In the glass industry, it varies from person to person, according to their preferences and different owners.
Four, price
Because the price of the aluminum alloy doors and windows and aluminum price level has a direct correlation, but on the whole in a period of aluminum alloy doors and windows performance price is relatively stable, in general, the price of high quality aluminum alloy is 30% higher than that of inferior aluminum alloy doors and windows products, poor quality aluminum alloy doors and windows usually made of aluminum profiles extrusion aluminum recycling contains a lot of impurities, with some aluminum wall thickness 0.6-0.8 mm, either from tensile strength or yield strength are ficantly lower than the relevant provisions of the state, this kind of aluminum alloy doors and windows, especially aluminum outdoor window is not safe, so the owners in the purchase of products do not map a cheap instead of himself and the personal safety of others.
