The whole production process is built around the core demand of bathroom waterproofing and moisture-proofing: aluminum alloy profiles are processed by high-precision CNC, and the corner joints are sealed with waterproof glue to prevent water vapor from penetrating into the interior; the door leaf frame and glass adopt an embedded slot design, matched with waterproof sealing glue to achieve double water vapor blocking; hinges and guide rails are all made of 304 stainless steel, which is corrosion-resistant and wear-resistant, suitable for long-term use in humid environments.The glass undergoes dual treatments of high-temperature tempering and frosting, with a uniform and delicate frosted surface and stable anti-peeping effect; after tempering, the impact resistance is greatly improved, and it breaks into granular shapes with higher safety. The product surface supports powder spraying, with optional colors such as white, gray and black. The coating is moisture-resistant and not easy to fade; the corners of the door frame are rounded to further enhance the safety of use, adapting to diverse scenarios such as homes and hotels.
The mainstream structure of the product is "aluminum alloy door frame + frosted tempered glass door leaf": the side-hung type is equipped with 304 stainless steel concealed hinges, which open smoothly without jamming, balancing aesthetics and stability; the sliding type is equipped with silent guide rails, sliding without noise, saving door opening space and adapting to small-sized bathroom doors. The connection between the door frame and the wall is filled with waterproof glue to prevent water vapor from penetrating into the wall through gaps.In terms of design, single-leaf and double-leaf customization are supported, and glass can be selected from frosted, Changhong, Changhong frosted and other styles to enhance privacy protection; the door lock is made of waterproof aluminum alloy to avoid rusting in humid environments, and some styles are equipped with magnetic locks for tighter closing. The overall design is simple and versatile, adaptable to various decoration styles such as Chinese style, modern style and minimalist style, while taking into account the three core needs of waterproofing, privacy and safety.
The core feature of the product is targeted waterproof and moisture-proof design: the aluminum alloy frame is corrosion-resistant and non-absorbent, fundamentally avoiding deformation and mildew in humid environments; the frosted tempered glass door leaf balances privacy and lighting, and the weather-resistant waterproof sealing strip can effectively block water vapor penetration and noise transmission, with a product service life of up to more than 12 years.The product is applicable to a wide range of scenarios, including home bathrooms, hotel guest room bathrooms, office building public bathrooms, apartment bathrooms and other spaces; it supports two opening methods: side-hung and sliding, adapting to different door opening sizes and layouts, with customizable colors and styles. It is a special door product for bathrooms that combines practicality and aesthetics.
Our bathroom door has significant differences from ordinary wooden doors and ordinary glass doors in terms of waterproof performance, adaptability and maintenance cost, as shown in the table below:
|
Comparison Item |
Our Bathroom Door |
Ordinary Wooden Door |
Ordinary Glass Door |
|
Waterproof Performance |
Excellent, IP54 waterproof rating, humidity-resistant |
Extremely poor, easy to absorb water, mildew, deform and crack |
Average, poor sealing, easy to penetrate water vapor |
|
Privacy Performance |
Good, frosted glass for anti-peeping, strong privacy |
Good, fully shielded, poor lighting |
Poor, clear glass without privacy protection |
|
Maintenance Cost |
Low, easy to clean, no special maintenance required |
High, regular moisture-proofing and paint repair needed |
Medium, sealing strips need regular replacement |
1. After installation, check the firmness of hinges/guide rails, the fit of sealing strips and the sensitivity of door locks; apply lubricating oil to hinges/guide rails every six months to ensure smooth opening.
2. For daily cleaning, wipe the frame and glass with clean water or neutral detergent, and avoid using corrosive reagents to prevent damage to the coating and sealing strips.
3. Avoid strong impact on the door leaf and glass to prevent glass breakage and door frame deformation; the frosted glass should be avoided from being scratched by sharp objects to avoid affecting the privacy effect.
4. Regularly check the waterproof performance of door locks and hinges. If rusting or jamming occurs, clean or replace them in time to ensure convenient use.
5. Keep the bathroom ventilated and dry to reduce water vapor retention and extend the service life of the door body and accessories.
Q: Will the frosted glass of the bathroom door fall off or fog up?
A: No. The glass and door frame are doubly fixed by embedded slots and waterproof glue, with strong firmness and not easy to fall off; the double-layer frosted tempered glass is filled with dry gas inside, with tight sealing and no risk of fogging or condensation.
Q: Is the sliding bathroom door easy to jam? How to avoid it?
A: It is not easy to jam under normal use. The guide rail is made of silent and wear-resistant material. Just keep the guide rail clean daily, avoid accumulation of hair and debris, and apply lubricating oil regularly to ensure smooth sliding.
