How to choose high-quality aluminum alloy bathroom doors

To select high-quality aluminum alloy bathroom doors, you can start from the following key aspects to ensure durability and user experience:

First, check the material and thickness

• Aluminum material quality: 6063-T5 aluminum alloy is preferred, featuring high strength, corrosion resistance, and a smooth surface without burrs. You can view the product inspection report to avoid recycling aluminum (which has many impurities and is prone to deformation).

• Profile thickness: The thickness of the aluminum material for the door frame and door leaf should be ≥1.2mm. If it is too thin, it is prone to shaking or deformation. Especially in the shower area, which is a long-term humid environment, the material needs to be thickened.

Second, pay attention to hardware Accessories

• Hinges/hinges: Choose 304 stainless steel or copper hinges, which have strong load-bearing capacity and good rust prevention. Test whether it opens and closes smoothly without any lag or abnormal noise.

• Pulleys (if there is a sliding door) : When choosing a sliding door, pay special attention to the pulleys. Nylon or metal materials are preferred. The larger the wheel diameter, the smoother the bearing, the easier it is to push and pull, and the more wear-resistant and long-lasting it is.

• Lock: The lock core is made of stainless steel or zinc alloy. It opens and closes smoothly and has good sealing performance to prevent water vapor from seeping in and causing rust.

Third, check the sealing performance and waterproof design

• Sealing strips: EPDM rubber sealing strips should be equipped at the edges of the door frame and door leaf. They are soft and elastic, capable of closely adhering to the door frame to prevent water from seeping out or noise from entering.

• Waterproof trough design: The lower edge of the door should have a groove or a water-blocking strip. A waterproof rubber strip can be installed at the bottom of the sliding door to prevent water from overflowing during a shower.

Fourth, look at the surface treatment process

• Oxidation treatment: High-quality aluminum alloy doors mostly adopt anodic oxidation or electrophoretic coating, with uniform surface color. They are not easy to leave marks when lightly scratched with a key, are scratch-resistant and anti-oxidation.

• Spraying process: If it is a sprayed paint surface, it is necessary to check whether the surface is smooth, free of bubbles or peeling. You can touch it with your hand to feel the texture. Inferior spraying is prone to fading or peeling.

Fifth, test the stability of the door

• Opening and closing test: Manually open and close the door to observe if it is smooth, without any left or right swaying or automatic offset, and there is no looseness at the hinge connection.

• Load-bearing test: Gently push the door leaf to feel if the weight is uniform. If it is too light, the material may be too thin; if it is too heavy, the hinge will bear a large load, affecting its lifespan.

Sixth, pay attention to the brand and after-sales service

Choose brands with a good reputation (such as Arrow, TATA, Oppein, etc.), as their craftsmanship and quality control are more reliable, avoiding inferior products from small factories.

Confirm the after-sales policy, such as the warranty period (at least 2-3 years), parts replacement service, etc., to facilitate subsequent maintenance.

Seventh, select the type as needed

• Swing door: Good sealing performance, suitable for small Spaces, but space should be reserved when opening the door.

• Sliding doors (sliding doors) : Save space. Attention should be paid to the anti-slip and waterproof design of the track.

Folding doors: Suitable for extremely small Spaces, but the hardware is prone to wear and tear, so the quality of the hinges should be given special attention.

Through the above screening points, not only can the quality of the aluminum alloy bathroom door be ensured, but also it can be adapted to the humid environment of the bathroom, reducing the trouble of later maintenance.
