Criterion 1, the thickness of 1 mm or more is appropriate
Aluminum alloy profiles have the characteristics of high strength, strong corrosion resistance, and resistance to deformation. Why do some aluminum alloy doors go out of shape before being used for one year? After analysis, under normal use conditions, the aluminum alloy doors are deformed, which may be caused by the thickness of the aluminum alloy profiles used.
It is understood that the aluminum alloy interior doors currently available for manufacturers in the building materials market are available in various thicknesses such as 0.8 mm, 1.0 mm, and 1.2 mm. Among them, aluminum alloy doors with a thickness of more than 1.0 mm have better strength and will not deform for 5 to 8 years under normal operating conditions. However, some small manufacturers cut corners in order to reduce consumption costs, and even use aluminum alloy profiles with a thickness of only 0.6 mm to make bathroom doors. This type of aluminum alloy door is prone to deformation due to insufficient material thickness.
Reveal: The thickness of the profile directly determines the quality of the aluminum alloy door. When manufacturers choose aluminum alloy doors, do not try to choose low-cost aluminum alloy doors with too thin profiles.
Rule 2. Look at the seal, look at the glass layer sealing strip
Another feature of aluminum alloy door is its strong decoration. The reporter visited some building materials stores and found that most aluminum alloy doors are inlaid with colorful art glass. These glasses are single-layered, as well as double-layer hollow glass with strong flatness and good sound insulation effect.
Aluminum alloy door experts introduced that choosing aluminum alloy doors with inlaid glass, especially products with hollow glass design, does not need to pay attention to its sealing function. If the airtightness is not good, it will cause dirt and dirt in the hollow layer, which will affect the appearance. The brand product adopts high-quality sealing tape to improve the predecessor's hot-pressing sealing technology to prevent all-round sealing solution, which can effectively prevent dust and water, and has a raised sound insulation effect.
Disclosure: To review the airtightness of the glass compartment of the aluminum alloy door, in addition to checking whether the glass glue coating on the front is tight, it is also necessary to check whether the sealing strip on the back glass of the door is flat, requiring no curling and no grooves. situation.
Criterion 3. Check whether there are defects in the welding process
"The production process of aluminum alloy doors is relatively simple, and many small manufacturers can produce them, but the quality is mainly based on the precision of the manufacturing process." According to experts of aluminum alloy doors, the welding process reflects the quality of aluminum alloy doors. The high-quality aluminum alloy doors are precisely machined and welded, especially the splicing parts are very flat. Inferior aluminum alloy doors and windows, consciously choose aluminum profile series and specifications, rough processing, and the corners of the door frame are helplessly spliced and flat, sometimes even showing a large gap.
When making purchases, producers should pay special attention to inspecting whether there are welding defects, such as open welding, missing welding, etc. It also depends on whether the door leaf and the door frame can be closed tightly, whether the gap can be evenly divided, and whether the opening can be sensitive.
Disclosure: After reviewing the welding process of the aluminum alloy door, the producer must carefully observe whether the paint surface of the product has a bright color and a clear texture, and pay attention to the paint surface must not have significant scratches, bubbles and other defects.
Criterion 4. Choose the quality of hardware accessories
Aluminum alloy doors are usually installed in humid environments such as bathrooms and kitchens. Therefore, the quality of hardware hinges, door handles and other accessories is the key to ensuring the service life of aluminum alloy doors.
Some people who renovate new homes are plagued by inferior hardware. "When I was decorating, I heard from my partner that the aluminum bathroom door is more durable, so I bought a set. At that time, I only paid attention to the quality of the door leaf and door cover, and neglected the hardware. Now the problem happens to be the hardware." Lin The teacher said that the bathroom door of his house had only been used soon, and the hinge was rusty, which caused the opening and closing of the door to be lax and unable to push or pull.
The quality of the accessories used in the aluminum alloy doors sold on the city roads is very different. The products of the right track brand will choose the galvanized hinges with high corrosion resistance and not easy to rust, and some small manufacturers will match the ordinary iron hinges. Producers should also be carefully identified when purchasing.
Revelation: In addition to checking whether the hinges can use materials that are not easy to rust, it is best to choose stainless steel door locks, handles and other hardware to avoid rust and affect the use. When purchasing aluminum alloy doors, pay attention to review the airtightness of the glass compartment.
The quality of aluminum alloy door fittings on the market is very different, and the manufacturer must carefully identify it when purchasing. The profiles produced by common aluminum alloy door factories on the market have a variety of thicknesses such as 0.8 mm, 1.0 mm and 1.2 mm. Producers should pay attention to measuring with a ruler when purchasing.
