The Matte Black Shower Grate is a floor drainage system component designed specifically for modern bathroom spaces. Made of 304 stainless steel with a thickness of 1.2mm, it features a professional matte black coating. Measuring 150 x 150mm (6 inches), its structure combines a square cover with side drain interfaces, providing stable drainage and anti-clogging functionality. It effectively drains water while enhancing the overall harmony of the bathroom space. Its matte black surface has a soft, non-reflective finish and a smooth feel, complementing a variety of bathroom styles.

• Compression Resistance Enhancement: The drain frame is manufactured using a one-piece stretch forming process, with a thickness of 1.2mm, and shows no deformation after withstanding a 250kg static pressure test. The corners feature a double-layer edge-wrapping structure, improving impact resistance by 35% compared to ordinary welded products. SGS mechanical load testing verifies that the cover can withstand over 100,000 repeated steps without loosening, meeting the needs of long-term, high-frequency use.

  
  

• Corrosion Resistance Upgrade: The surface coating is a vacuum physical deposition (PVD) matte black, with a film hardness of approximately HV2000, about 4 times higher than electroplating. After 24 hours of neutral salt spray testing and high-temperature damp heat aging testing, the color remains stable with no rust marks. The product has strong acid and alkali resistance and can withstand long-term contact with chlorine-containing cleaning solutions without corrosion.

  
  

• High Flow Rate: The internal water channel adopts a lateral flow guidance design, and the fluid channel has been optimized through numerical simulation, achieving a maximum drainage capacity of 40 liters/minute. The number and distribution of drainage holes have been optimized through experimental comparison, maintaining a constant average drainage rate during a 10° tilt test, reducing the likelihood of water accumulation on the ground. A 50mm deep physical water seal layer at the bottom prevents odor backflow and ensures stable water flow.

  
  

• Refined Appearance: The surface undergoes 400-mesh fine brushing and multiple micro-spraying treatments, achieving a gloss level of only 10–12 GU, resulting in a delicate feel. Laser-cut long slots have smooth, burr-free edges, with a hole spacing error of less than ±0.05mm. Color is achieved through PVD vacuum coating, with a ΔE color difference controlled within 0.8, ensuring high overall visual uniformity. Suitable for high-end residences and designer projects.

  
  

• Easy Installation: The modular design allows for independent disassembly of the cover and base. The product has an installation depth of 85mm and can be directly embedded in standard waterproofing layers. The 50mm diameter interface offers strong versatility, allowing connection to PVC, ABS, or metal pipes. Built-in guide rings prevent misalignment and allow for a 2° angle adjustment to fit ground slope. Maintenance is as simple as lifting the cover to clean the filter, improving maintenance efficiency by 45%.

• Residential Bathrooms: For family bathrooms or shower areas with separate wet and dry areas. The standard 150×150mm size fits most floor tile drain holes, flush with the floor after installation, non-slip and preventing water accumulation. The odor-resistant structure keeps the air fresh and reduces bathroom odor problems.

  
  

• High-End Hotels: Widely used in hotel suites, business rooms, and spa bathing spaces. Its matte black appearance coordinates with metallic accessories, conforming to modern minimalist design styles. Stable drainage efficiency ensures rapid drainage even when multiple rooms are in use simultaneously.

  
  

• Public Facilities: Suitable for high-frequency areas such as airports, changing rooms, and gyms. The product has passed corrosion and pressure resistance tests, resisting frequent washing, hot water impacts, and chemical cleaning agent erosion, reducing maintenance costs.

  
  

• Commercial Real Estate: For apartments, office buildings, and commercial building projects. Standardized specifications facilitate bulk purchasing and centralized construction, with high installation compatibility. Its modern appearance and durable color coordinate with different floor tile materials.

1. What material is this drain made of? What pressure can it withstand?

This product is made of SUS304 stainless steel, 1.2mm thick. SGS testing shows it can withstand 250kg of static pressure without deformation, making it suitable for long-term use in homes and commercial settings.

2. Will the matte black surface fade?

No. It uses PVD vacuum coating technology, with a film hardness of HV2000. After 24 hours of salt spray and damp heat testing, there was no fading or peeling, and the color can be maintained for over ten years.

3. Is the cover removable? How to clean it?

Yes, it is removable. It uses a snap-on structure; users can easily lift and remove the cover. Regularly cleaning the inside to remove hair and impurities will maintain smooth drainage.

4. Does it support personalization?

Yes, it does. Customization is available for laser logos, surface colors (such as rose gold, brushed silver, gray, gold), and size specifications, suitable for OEM/ODM projects.

5. What types of pipes is the drain outlet compatible with?

The standard interface diameter is 50mm, compatible with PVC, ABS, and stainless steel drainage systems. Interface dimensional tolerances are controlled within ±0.3mm, ensuring stable and reliable installation and sealing.
