Established in 2000, Ningbo Xianglong Metal Products Co., Ltd. has evolved from a specialized stamping workshop into a global powerhouse for bathroom channel drains and niche metal products. With over 13,000 square meters of production space and a workforce of 100+ skilled professionals, we represent the pinnacle of Chinese metal engineering.
Our facility is equipped with state-of-the-art CNC laser cutting, precision bending, and automated welding technology. This allows us to maintain a 100% responsibility "Zero Risk" collaboration model. From 304/316 grade stainless steel to PVD vacuum coating, we ensure every product exceeds international standards for corrosion resistance and hydraulic efficiency.
Recognized by German TUV, ISO 9001, and ISO 14001, our quality management system is built for the global stage. We serve world-renowned brands such as AOB (USA), WIRQUIN (Europe), and DELTA (Australia), providing them with the high-capacity drainage solutions required for modern commercial and residential architecture.
Strategic insights for procurement directors and architectural designers.
The rise of aging populations and modern aesthetic trends has made "curbless" showers a global standard. Linear channel drains are the critical component enabling these barrier-free environments, allowing for a single-slope floor design that is both safer and more visually expansive.
Standard 201 stainless steel is no longer sufficient. Global markets now demand SUS304 as a minimum, with SUS316 becoming the choice for coastal developments and high-end hospitality. Our PVD (Physical Vapor Deposition) coatings provide anti-fingerprint and scratch-resistant finishes that last for decades.
Intelligent mechanical seals (gravity-fed or spring-loaded) are replacing traditional water traps in areas where evaporation is an issue. Our "Insect Proof" and "Odor Proof" patented technologies ensure sanitary safety even in low-usage guest rooms or seasonal balconies.
For hotels and resorts, we provide custom 360° rotating outlets that simplify plumbing in multi-story renovations, reducing labor costs by 30%.
Heavy-duty, wide-format drains designed for high-traffic environments like swimming pools, gyms, and industrial washrooms with enhanced hair-catching mechanisms.
Seamless wall niches and "tile-in" invisible linear drains that allow the floor tile to be inserted into the drain grate for a near-invisible finish.
Compatibility with 2-inch standard hub outlets. Support for UPC and ASME standards to ensure seamless inspector approval in US and Canada.
Compliant with EN 1253 standards. Low-profile siphons designed for European shallow floor construction, featuring high-flow performance.
WaterMark certified materials. Specialized 316-grade stainless steel options for coastal residential developments in Oceania.
Precision-guided cutting for complex geometric patterns in grates.
Leak-proof structural integrity through robotic precision.
Advanced vacuum plating for luxury aesthetic finishes.
Final rigorous testing for every production batch.
Linear drains only require a floor slope in one direction toward the channel, whereas center drains require the floor to slope from all four sides. This makes linear drains ideal for large-format tiles and curbless, barrier-free entry showers.
Our standard linear drains provide a flow rate of approximately 30-35 Liters per minute. For high-flow commercial applications, we offer custom dual-outlet designs that can exceed 60L/min, preventing water pooling in large showers.
Traditional painting or powder coating can chip or peel over time. Our PVD (Physical Vapor Deposition) process bonds the finish at a molecular level to the stainless steel, making it highly resistant to detergents, scratching, and oxidation.
Yes. We have worked with international brands to develop proprietary lengths (up to 2000mm+), specialized flange designs for specific waterproofing membranes, and custom grate patterns that match corporate branding.
Partnered with World-Renowned Brands: AOB, ASTERM, WIRQUIN, DELTA, COFLEX.
Partner with China's leading bathroom channel drain factory for precision, scale, and uncompromising quality.
