The method of choosing aluminum ceiling:
Aluminum gussets come in many sizes, including the panel width, thickness, and height of the hem. The selection should be based on the characteristics of the bathroom at home. The aluminum gusset plate is divided into two types: punched and flat. The surface punching can be ventilated and sound-absorbing, and the inside of the gusset is covered with a film cushion. The moisture can be absorbed by the film through the punching hole, so it is most suitable for kitchens with more moisture. 600mm × 600mm microporous square plates, C150, C100 strips and 300×300, 300×600 aluminum gussets are the most widely used on the market.
The quality of aluminum gussets is not thin and thick. The key lies in the texture of aluminum. The general aluminum gussets for engineering use are 0.8 mm or even thicker. Why? Because some engineering gussets are very long, in order to prevent deformation. Therefore, it should be thicker and harder. On the contrary, the aluminum plate for home decoration is rarely more than 4 meters, and there is no heavy object on the ceiling of the aluminum buckle. Therefore, the aluminum plate of the home decoration can be said to be 0.6. The millimeter is enough. So, why do you go to the building materials city, a lot of salesmen tell you about their 0.8mm, and friends say that someone introduced him to 0.88mm; it is often because their boards can't, so they can only use the thickness to be human- - It is really devastating.
Explicitly tell everyone that 0.6 mm is enough. Take the aluminum plate of an imported brand with a high reputation on the market as an example. Its price is more than 300 yuan per square meter, but what is its thickness? 0.5mm, not as good as 0.6mm! Why, the board is not good or bad. It lies in the thickness but in the substrate. In fact, if the aluminum gussets you consult are brand names, in the mid-range, most of them are 0.6 mm.
As for why some brands are 0.8 mm, they are not good. Some miscellaneous brands use cans of aluminum. Because of the quality problems of aluminum itself, they want to make the aluminum plate very thin, but it is impossible because The aluminum is not good, the board has no way to pull it evenly, so they can only do it in thick.
Therefore, in order to identify the aluminum gusset plate, in addition to paying attention to the surface finish, it is also necessary to observe whether the thickness of the board is uniform, and feel the elasticity and toughness by pinching the board with a hand.
Note on the purchase of aluminum ceiling:
The main thing to choose an aluminum ceiling is to look at its material and not to focus on its thickness. According to the design principle, the thickness of ordinary home improvement strips can reach 0.5mm, 0.6mm, and very few to 0.8mm. Why? Because of the aluminum alloy used, it is not necessary to be thick enough. The span of the buckle is not too large, and it is not necessary to use it as thick.
First look at the material of the doors and windows. The aluminum profiles, thickness, strength and oxide film used for high-quality aluminum alloy alloy doors and windows are in compliance with relevant national standards. The wall thickness should be above 1.2mm and the thickness of the oxide film should be 10 microns. If you exceed national standards, even products that meet European standards are of course the best choice.
Second, look at the processing of doors and windows. High-quality aluminum alloy alloy doors and windows, fine processing, careful installation, good sealing performance, and easy to switch. Inferior aluminum alloy doors and windows, materials and specifications are not up to standard, and the processing is also uneven, poor sealing performance, not only leaking wind and rain, but also in the case of strong winds and excessive external force, glass cracking is easy to occur Causes the glass to scrape or fall.
Third, look at the appearance of the doors and windows. The appearance of doors and windows is also a key link. The surface of aluminum alloy doors and windows has an artificial oxide film and is colored to form a composite film layer. This composite film not only has corrosion resistance, wear resistance, but also has certain fireproof function, and the gloss is extremely high. To try to compare as much as possible, try to choose the products of regular aluminum alloy doors and windows manufacturers, select the products that are precise, accurate, open and closed, light and flexible, noise-free, and elegantly decorated.
Fourth, look at the price of doors and windows. Under normal circumstances, high-quality aluminum profile alloy doors and windows due to high production costs, the price is about 30% higher than inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have much lower tensile strength and yield strength than the relevant national standards. They are very unsafe to use and must not neglect their own safety factors because of their greediness. .
Fifth look at the performance of doors and windows. Aluminum profile alloy doors and windows usually assess the following main properties: strength, air tightness, water tightness, opening and closing force, sound insulation, heat insulation, durability of nylon guide wheels, durability of opening and closing, and other factors.
