Ningbo Xianglong Metal Products Co., Ltd. represents the pinnacle of specialized stainless steel drainage manufacturing. With over a quarter-century of expertise, we have transitioned from a localized metal workshop to a global leader in ODM/OEM services. Our "Information Gain" lies in our deep understanding of metallurgical integrity and hydraulic efficiency.
Unlike standard manufacturers, we integrate the entire value chain. From raw material procurement (AISI 304/316) to precision laser cutting and advanced PVD (Physical Vapor Deposition) surface treatments, every Tile Insert Drain leaving our factory is a testament to Chinese industrial resilience and innovation.

We utilize ultra-high-power CNC laser cutting to ensure tolerances within ±0.05mm. This is critical for Tile Insert Drains where the gap between the tile and the frame must be perfectly uniform for "invisible" aesthetics.
Our robotic argon arc welding ensures leak-proof seams. Every linear drain undergoes a 24-hour pressure test to guarantee structural integrity in high-moisture environments.
Moving beyond basic brushing, we offer PVD vacuum coating in Matte Black, Brushed Gold, and Rose Copper, providing a 3H hardness rating and superior salt-spray resistance.
The next decade of bathroom technology focuses on "Seamless Integration." At Xianglong, our R&D roadmap includes the development of IoT-integrated sensors for floor drains to detect humidity levels and blockages, alongside the use of antimicrobial coatings to enhance hygiene in public hospitality projects.
In an era of volatile logistics, our factory provides a "Risk-Free" hub for international procurement. We bridge the gap between Chinese efficiency and global compliance.
Compliance with UPC/cUPC standards. Our partnerships with brands like AOB ensure our drains meet the stringent US plumbing codes.
Focus on EN 1253 standards. Working with ASTERN & WIRQUIN, we prioritize low-profile designs for European thin-bed installations.
Meeting WaterMark and WMTS-040 requirements. Heavy-duty 316-grade stainless steel options for coastal luxury developments.
Our Smart Factory Floor: Integrating automated production with human craftsmanship.
Tile-in solutions allow homeowners to use the same floor tile on the drain cover, creating a minimalist, uninterrupted floor pattern.
High-flow linear drains for luxury hotels and spas, where aesthetics must meet heavy daily usage and rigorous cleaning protocols.
Heavy-duty stainless steel drains designed for factories and public restrooms, focusing on anti-clogging and high-speed drainage.
Our facility is certified by TUV German Standards and maintains ISO 9001:2015 Quality Management and ISO 14001:2015 Environmental Management systems. We are the trusted choice for world-renowned brands such as COFLEX, DELTA, and WIRQUIN.
