Thickness
Aluminum alloy profiles are characterized by high strength, strong corrosion resistance, and resistance to deformation. Why then do some aluminum alloy doors warp before even a year of use? Analysis shows that under normal use, deformation of aluminum alloy doors may be due to the use of aluminum alloy profiles that are too thin. It is understood that aluminum alloy interior doors available in building materials markets have profiles of various thicknesses, including 0.8 mm, 1.0 mm, and 1.2 mm. Aluminum alloy doors with a thickness of 1.0 mm or more have better strength and, under normal use, will not deform for 5-8 years. However, some small manufacturers cut corners to reduce production costs, even using aluminum alloy profiles with a thickness of only 0.6 mm to make bathroom doors. These types of aluminum alloy doors are prone to deformation due to insufficient material thickness.
Reminder:
The thickness of the profile directly determines the quality of the aluminum alloy door. When purchasing aluminum alloy doors, consumers should not be tempted by low prices and choose doors with excessively thin profiles.
Sealing Strip:
Another characteristic of aluminum alloy doors is their strong decorative appeal. A reporter visited several building materials markets and found that most aluminum alloy doors were inlaid with artistic glass in various colors and patterns. These glasses included single-layered glass as well as double-layered insulated glass with a strong three-dimensional effect and good sound insulation.
An aluminum alloy door expert explained that when choosing aluminum alloy doors with inlaid glass, especially those with insulated glass designs, it is crucial to pay attention to their sealing performance. Poor sealing will lead to dirt and grime accumulating in the hollow layer, affecting the aesthetics. Branded products use high-quality sealing strips and advanced hot-press sealing technology for comprehensive sealing, effectively preventing dust and water damage, and providing excellent sound insulation.
Reminder: To check the sealing of the glass layer of an aluminum alloy door, in addition to checking whether the sealant coating on the front is tight, also check whether the sealing strip on the back of the door is flat, without curling edges or detachment.
Welding Process
"The production process of aluminum alloy doors is relatively simple, and many small manufacturers can produce them, but the quality mainly depends on the fineness of the manufacturing process," the aluminum alloy door expert explained. The quality of the welding process reflects the quality of the aluminum alloy door. High-quality aluminum alloy doors are finely crafted with meticulous welding, resulting in perfectly smooth joints. Inferior aluminum alloy doors and windows, on the other hand, are made with poorly selected aluminum profiles and specifications, resulting in shoddy workmanship. The corners and other areas of the door frame may not be smoothly joined, sometimes even with large gaps.
When purchasing, consumers should pay special attention to checking for welding defects such as incomplete welds or missing welds. They should also check if the door leaf and frame close tightly, if the gaps are uniform, and if the door opens smoothly.
Reminder: After checking the welding process, consumers should carefully examine the paint finish for bright colors and clear textures. The paint should be free of obvious scratches, bubbles, or other defects.
Accessory Quality: Aluminum alloy doors are typically installed in damp environments such as bathrooms and kitchens. Therefore, the quality of hardware such as hinges and door handles is crucial to ensuring the lifespan of the aluminum alloy door. Many consumers struggle when purchasing door materials because they are unsure what type of door to choose. Many consumers want to buy an inexpensive, high-quality, and sturdy door. According to a well-known brand store, aluminum alloy doors are the most common type of door they sell.
Some homeowners renovating their new homes are plagued by substandard hardware. "When I was renovating, a friend recommended aluminum alloy bathroom doors, saying they were more durable, so I bought a set. At the time, I only focused on the quality of the door leaf and frame, neglecting the hardware, and the problem is precisely with the hardware," said Mr. Lin. His bathroom door, after only a short time, became impossible to open and close due to rusted hinges.
The quality of accessories used in aluminum alloy doors sold on the market varies greatly. Reputable brands use galvanized hinges that are highly corrosion-resistant and rust-resistant, while some smaller manufacturers use ordinary iron hinges. Consumers should carefully check these differences when purchasing.
Reminder: When buying aluminum alloy doors, in addition to checking whether the hinges are made of rust-resistant materials, it is best to choose stainless steel door locks, handles, and other hardware to prevent rust from affecting usability. When purchasing aluminum alloy doors, pay attention to checking the airtightness of the glass partition.
The quality of aluminum alloy door accessories on the market varies greatly, and consumers should carefully distinguish between them when purchasing. Common aluminum alloy door manufacturers produce profiles with thicknesses such as 0.8 mm, 1.0 mm, and 1.2 mm; consumers should measure these thicknesses with a ruler when buying.
