The most important choice of aluminum ceiling is to look at its material, do not focus on its thickness. According to the design principle, the ordinary home improvement strip board thickness reaches 0.5mm, 0.6mm can, very few to 0.8mm, why?? is due to the use of aluminum alloy material reasons, not very thick enough, and then there is no more than the span of home decoration, and there is no need to use so thick.
First look at the door and window materials. High-quality aluminum alloy doors and windows used aluminum, thickness, strength and oxidation film, are in line with the relevant national standards, wall thickness should be above 1.2mm, oxide film thickness should reach 10 microns. If more than the national standards, even to achieve the European standard products
Of course it's the best choice.
Second look at the door and window processing. High-quality aluminum alloy doors and windows, processing fine, installation stress, good sealing performance, switch freely. Inferior aluminum alloy doors and windows, materials and specifications are not up to standard, but also processing is uneven, poor sealing performance, not only leakage of air leaks, but also in the face of strong wind and excessive external forces are prone to the phenomenon of glass burst, resulting in glass scraping or falling.
Third look at the appearance of windows and doors. The appearance of doors and windows is also a key link, aluminum alloy doors and windows have artificial oxide film and coloring to form a composite film, the composite film not only corrosion resistance, wear-resistant, and has a certain fire function, high gloss, in the selection to be as much as possible, choose the normal aluminum alloy doors and windows manufacturers of products, select processing precision, accurate, Open and close light flexible, no noise, and decorative effect of elegant products.
Look at the price of doors and windows. In general, high-quality aluminum alloy doors and windows due to high production costs, the price is higher than inferior aluminum alloy doors and windows about 30%. Some wall thickness only 0.6-0.8 mm aluminum alloy doors and windows, tensile strength and yield intensity is much lower than the relevant national standards, use is not safe, must not be greedy for a while to ignore their own security factors.
Look at the performance of doors and windows. Aluminum alloy doors and windows usually examine the following main properties: Strength, tightness, water tightness, opening and closing, sound insulation, heat insulation, nylon guide wheel durability, open locking durability and other factors.
