Explore our certified commercial-grade brass fixtures, custom center hole sink mixers, and high-pressure shower components configured for global importers, distributors, and engineering contractors.
The contemporary commercial and residential plumbing landscape demands strict compliance with mechanical integrity, fluid dynamics, and environmental metallurgy. A single hole or 4-inch center hole sink mixer represents the pinnacle of compact hydraulic engineering, combining hot and cold water blending functions within a single monolithic valve body.
High-grade center hole sink mixers rely on low-lead HPb59-1 brass or Dezincification-Resistant (DZR) CW602N brass alloys. This ensures total protection against structural degradation caused by aggressive water chemistries, while adhering to international NSF/ANSI 61 and California Proposition 65 drinking water safety directives.
At the core of every mixer is a ceramic disk cartridge rated for over 500,000 operational cycles (compliant with EN 817 standards). Engineered with diamond-hard sintered alumina (Al₂O₃), these cartridges guarantee drip-free performance under variable dynamic water pressures ranging from 0.05 MPa to 1.0 MPa.
Utilizing state-of-the-art Physical Vapor Deposition (PVD) technology alongside multi-layer electroplating, our center hole mixers feature extreme surface hardness exceeding 2000 HV. Finish options include Brushed Nickel, Gunmetal Gray, Matte Black, and Rose Gold—passing 240-hour Neutral Salt Spray (NSS) corrosion testing.

Located in Yuhuan, Taizhou, Zhejiang Province, our enterprise sits at the absolute center of the world's most sophisticated sanitaryware manufacturing ecosystem. Yuhuan accounts for a massive proportion of global brass valve and faucet exports, delivering unparalleled cost efficiencies, raw material accessibility, and technical specialization.
Unlike traditional trading intermediaries, our joint manufacturing alliance owns and operates dedicated electroplating plants, spraying workshops, and specialized PVD coating facilities. From raw brass gravity casting and CNC precision machining to robotic polishing and automated surface finishing, every production phase is executed under strict quality control.
Our operational management team possesses over 20 years of hands-on expertise in technical mold design, metallurgical engineering, and global OEM/ODM production processes. This extensive legacy enables rapid prototyping, custom architectural customizations, and zero-defect volume manufacturing for international B2B partners.
We control the direct supply chain for all structural accessories—including specialized ceramic valve cores, brass connecting nuts, flexible stainless steel inlet hoses, popup basin drains, and high-pressure divert valves. This guarantees perfect thread compatibility and consistent structural integrity across product lines.
We understand the complex supply chain risks faced by international B2B procurement officers, real estate project developers, and brand owners. Beyond our core manufacturing capabilities, we operate as a dedicated procurement agent and independent third-party inspection entity in China.
We tailor products strictly to custom CAD/BIM specifications. Whether adjusting spout height, integrating custom branded laser logos, or engineering specific thread sizes (NPT, G1/2, G3/8) for North American or European markets, our engineering team brings concepts to life within 15 days.
Leveraging our 20 years of sanitaryware production management, we offer comprehensive factory auditing, inline production inspections, pre-shipment quality control (AQL 2.5 standards), and raw material spectro-analysis for overseas clients sourcing throughout Asian supply hubs.
Eliminate multi-vendor friction. We consolidate complete bathroom and kitchen packages—combining center hole sink mixers, freestanding tub fillers, shower systems, concealed stop valves, and drain hardware into single streamlined sea freight shipments with full export documentation.
Our company is located in Yuhuan, Taizhou, Zhejiang. We are a trading company jointly established by many professional bathroom manufacturers, with the advantages of low cost and high quality. Our products include handheld showerheads, shower hoses, spray guns, drains, angle valves, ceramic valve cores, brass accessories, water outlet pipes, and towel racks.
We have 10-20 years of production experience in these factories, and our organizers also have 20 years of experience in bathroom production management. We are the source factory for all accessories, with our own electroplating factory, spraying workshop, and PVD coating workshop, capable of producing all colors for the bathroom industry.
Our company can also help customers find high-quality products, and can also become an independent inspection company for customers. We understand the challenges businesses face when sourcing products that meet their specific requirements. That's why we offer a tailored approach to product sourcing, leveraging our extensive network of suppliers and manufacturers to connect our customers with the best products on the market. Whether sourcing raw materials, components or finished products, our team is dedicated to finding the right solution for our customers.
