In the high-end architectural landscape, the shift from traditional grating to Invisible Floor Drains (Tile-Insert Systems) is not merely aesthetic but a response to modern hygiene and spatial integration requirements. Global demand is surging in luxury hospitality and urban high-rise developments where "seamless" flooring is the gold standard.
Modern invisible drains now incorporate gravity-fed self-sealing mechanisms. This ensures that while the drain remains hidden beneath the tile, its performance in preventing sewer gas reflux and managing high volumetric water flow (exceeding 35L/min) is superior to traditional 100mm square drains.
Durability in "invisible" installations is critical because replacement involves tearing up tiles. Professional manufacturers like Ningbo Xianglong prioritize SUS304 and SUS316L grades, utilizing PVD (Physical Vapor Deposition) for finishes like Matte Black and Brushed Gold to ensure corrosion resistance for 25+ years.
Established in 2000, Ningbo Xianglong Metal Products Co., Ltd. has evolved into a global leader in high-performance drainage and metal storage solutions. With a sprawling 13,000 sqm facility and over 100 specialized employees, we embody the pinnacle of "Made in China 2025" quality standards.
Our portfolio includes TUV, ISO 9001, and ISO 14001 certifications, serving tier-one global brands including AOB (USA), DELTA (Australia), and WIRQUIN (Europe). We provide a one-stop ODM/OEM customization service that handles everything from hydraulic R&D to final PVD surface treatment.

Our "Invisible" drains require zero-tolerance fitment for tile inserts. We utilize CNC laser cutting and automated robotic welding to ensure every seam is watertight and every angle is perfectly 90 degrees, preventing installation headaches on-site.
Located in the Ningbo industrial hub, we leverage localized raw material sourcing and port proximity to offer shorter lead times. Our integration of the entire value chain—from design to assembly—means we can pivot to custom architectural requirements faster than traditional mass-producers.
Every batch undergoes hydrostatic testing, salt spray testing (for finish durability), and flow rate verification. Our "Zero Risk" commitment means we take 100% responsibility for structural integrity, essential for commercial contractors and global developers.
In hotels like Hilton or Marriott, Invisible Linear Drains are used to create "barrier-free" walk-in showers, enhancing the premium feel while ensuring rapid drainage for high-pressure rainfall showerheads.
Urban developers in New York and London require SS316 drains that resist corrosion from chlorinated water and cleaning agents, specifically in balcony and indoor wetroom applications.
For commercial kitchens and cafes, our Stainless Steel Coffee Bean Silos and large-format floor drains offer the hygienic, easy-to-clean surfaces required by health safety regulations.
High-flow triangular and linear drains are essential for pool decks and patios, where they must handle high UV exposure and chemical-rich environments without discoloration.
