Aluminum alloy is a kind of metal raw material widely used in various modern industries. Especially in the door and window industry in the modern construction industry, it is widely used. The high-quality aluminum alloy doors and windows not only have a gorgeous appearance, but also exquisite workmanship and long service life. The inferior aluminum alloy doors and windows not only have no texture, but also show the owner's life taste, and the service life will not be too long. How can I buy high-quality aluminum alloy doors and windows in the process of selecting aluminum alloy doors and windows?
thickness
The aluminum alloy profile has the characteristics of high strength, strong corrosion resistance and low deformation. Why are some aluminum alloy doors that have not been used for a year? After analysis, in the case of normal use, the aluminum alloy door is deformed, probably because the thickness of the aluminum alloy profile used is too thin. It is understood that the aluminum alloy interior doors for consumers to purchase in the building materials market have various thicknesses such as 0.8 mm, 1.0 mm and 1.2 mm. The aluminum alloy door with a thickness of 1.0 mm or more has better strength and will not be deformed for 5 to 8 years under the premise of normal use. However, some small manufacturers cut corners in order to reduce production costs, and even used aluminum alloy profiles with a thickness of only 0.6 mm to make bathroom doors. Such aluminum alloy doors are prone to deformation due to insufficient thickness of the material.
Reminder: The thickness of the profile directly determines the pros and cons of the aluminum alloy door. When consumers buy aluminum alloy doors, don't try to use cheap aluminum alloy doors with thin profiles.
sealing strip
Another feature of the alloy door is its strong decoration. The reporter visited some building materials stores and found that most of the aluminum alloy doors are inlaid with various artistic glasses. These glasses have a single layer, and also have double-layer insulating glass with strong stereoscopic effect and good sound insulation effect.
The introduction of aluminum alloy door experts, choose aluminum alloy doors with inlaid glass, especially products designed with insulating glass, we must pay attention to its sealing performance. If the sealing property is not good, the hollow layer will be contaminated and the appearance will be affected. The brand products adopt high-quality sealing strips and are fully sealed by advanced hot-press sealing technology, which can effectively prevent dust and water, and the sound insulation effect is outstanding.
Reminder: Check the sealing of the aluminum alloy door glass compartment. In addition to checking whether the front glass glue coating is tight, check whether the sealing strip on the back glass is flat, and it is required to have no curling or grooving.
Process welding
"The production process of aluminum alloy doors is relatively simple, many small manufacturers can produce, but the quality is mainly in the production process is fine." Aluminum alloy door experts, the level of welding technology reflects the quality of aluminum alloy doors. High-quality aluminum alloy door, fine processing, welding, especially the stitching parts are very flat. The inferior aluminum alloy doors and windows, blindly use the aluminum profile series and specifications, the processing is shoddy, the corners of the door frame can not be flattened, and sometimes even larger gaps appear.
When purchasing, consumers should pay special attention to check for welding defects, such as open welding and leakage welding. Also check whether the door and the door frame are closed, whether the gap is uniform, and whether the opening is flexible.
Reminder: After the customer checks the welding process of the aluminum alloy door, it is necessary to carefully check whether the paint surface of the product is bright and the texture is clear. Note that the paint surface cannot have obvious scratches, bubbles and other defects.
Accessory quality
Aluminum alloy doors are usually installed in humid environments such as bathrooms and kitchens. Therefore, the quality of hardware hinges, door handles, etc. is the key to ensuring the service life of aluminum alloy doors. Many consumers are very upset about buying building materials. Because I don't know what kind of door to buy. Many consumers want to buy a cheap, good quality and relatively strong door. According to a well-known brand store business, the door that they sell at the most is the aluminum alloy door.
Some new homes have been plagued by inferior hardware. “When I was renovating, I heard that the bathroom door of the aluminum alloy was more durable, so I bought one. I only paid attention to the quality of the door leaf and the door cover, and ignored the hardware. Now the problem is exactly on the hardware.†Mr. Lin said The bathroom door of his house was used very soon, because the hinge was rusted and the switch was not tight, and it could not be pushed or pulled.
The quality of the accessories used in the aluminum alloy doors sold in the market varies greatly. The products of the regular brand will use galvanized hinges with high corrosion resistance and rust resistance. You can go to Jizheng Building Materials to inquire about the relevant manufacturers, and some small manufacturers. Will match the ordinary iron hinge. Consumers should also carefully identify when purchasing.
Reminder: In addition to looking at the hinges for the use of materials that are not easy to rust, it is best to choose stainless steel door locks, handles and other hardware to prevent rust and affect the use. Pay attention to check the tightness of the glass compartment when purchasing aluminum alloy doors.
The quality of aluminum alloy door fittings on the market varies greatly, and consumers should carefully identify them when purchasing. The aluminum alloy door factories commonly used in the market produce profiles of various thicknesses such as 0.8 mm, 1.0 mm and 1.2 mm. Consumers should pay attention to the measurement with a ruler.

Metal silicon, also known as Crystalline Silicon or Industrial Silicon, is mainly used as an additive to non-ferrous based alloys. Metal silicon is a product made of quartz and coke in an electric furnace. The content of silicon in the main component is about 98% (in recent years, 99.99% of Si is also contained in metal silicon), and the remaining impurities are iron and aluminum. , calcium, etc.
