High-Performance Commercial & Residential Sink Strainers
Explore our primary tier of engineered drain components, manufactured to strict ASME A112.18.2 / CSA B125.2 benchmarks.
Macro-Level Sourcing Strategies in the Global Plumbing Infrastructure
In today's highly dynamic international supply chain, procurement directors, OEM brands, and wholesale distributors face unprecedented structural pressure. Raw material fluctuations in CW617N and C37700 brass alloys, combined with evolving regional compliance standards like AB1953 lead-free mandates and NSF/ANSI 61 requirements, mean sourcing decisions can no longer be based solely on piece-part unit costs.
Modern sink strainer assemblies serve as critical hydraulic isolation points in commercial kitchens, residential housing, and industrial food processing environments. A failure in thread tolerances, corrosion resistance, or rubber seal elasticity leads directly to costly water damage claims and brand degradation. Choosing a certified Chinese manufacturing partner with robust technical depth, advanced metallurgic controls, and vertical integration guarantees both operational reliability and margin protection.
Metallurgical Integrity
Utilizing heavy-duty solid forged brass and high-nickel 304 stainless steel alloys that exceed minimum wall-thickness requirements to prevent stress corrosion cracking (SCC) under continuous hydraulic pressure.
Precision CNC Machining
Computer-controlled threading ensures seamless connection with standard 1-1/2" NPSM tailpieces and locknuts, eliminating cross-threading and installation failures on job sites.
Dual-Basing Risk Protection
With primary operations in Yuhuan, Zhejiang and an expanded automated manufacturing center in Kabinburi, Thailand, buyers gain supply security against geopolitical tariffs and regional disruptions.

Engineered for Diverse Global Installation Environments
From heavy commercial food service facilities to high-density residential developments, our sink strainers perform flawlessly across specialized operational demands.
Residential Multi-Family
Designed for fast, trouble-free installation by plumbing contractors in high-density housing projects. The EZ-Lock and Spin & Lock mechanisms significantly reduce labor time per unit during construction phases.
Commercial Hospitality & Foodservice
Equipped with heavy-gauge deep baskets capable of handling high volumes of food debris without clogging. Resistant to aggressive cleaning detergents, boiling water dumps, and severe thermal shocks.
Recreational Vehicles (RV) & Marine
Compact, vibration-resistant strainer body designs tailored for mobile living spaces. Built to withstand continuous motion, fluctuating water temperatures, and space-constrained undersink piping.
China & Thailand Dual Production Bases
To safeguard our global partners from shifting trade policies and supply bottlenecks, JANA PLUMBING CO., LTD. expanded manufacturing operations beyond our Zhejiang headquarters to Kabinburi, Thailand in December 2023.
Spanning 14,400 square meters, our Thailand facility (Gateway Enterprise Corporation) is equipped with automated hydraulic forming presses, multi-axis CNC lathes, and automated polishing systems. This dual-origin capability allows North American and European buyers to optimize tariff structures while maintaining 100% component interchangeability and strict quality oversight.
Compliance & Quality Management
Our factories operate under ISO 9001 quality management systems. Individual product series maintain accredited third-party listings for key global markets:
- cUPC / UPC Certification: Listed by IAPMO R&T under file nos. 6229, 8175, and 12307.
- Lead-Free Verification: Certified under California AB1953 and NSF/ANSI 372 standards.
- Quality Audits: Certified compliant with BRC global standards for operational hygiene and traceabilty.
- Dimensional Rigor: Fully compliant with ASME A112.18.2 / CSA B125.2 plumbing fixture requirements.
Technology Roadmap & Sustainability Horizons (2025–2030)
Our engineering team continuously innovates to meet evolving environmental regulations, smart building requirements, and modern kitchen aesthetic trends.
Zero-Landfill Scrap Recycling
Automated brass chip collection and closed-loop remelting system reduces virgin raw material draw by 35%, supporting global corporate ESG objectives.
Advanced PVD Finish Tech
Physical Vapor Deposition (PVD) titanium plating lines create eco-friendly, ultra-hard decorative coatings (Matte Black, Brushed Brass) that resist abrasion 5x better than traditional electroplating.
Automated AI Optical QC
Inline high-resolution machine vision cameras instantly detect visual finish defects, thread burrs, and casting micro-porosity before products leave the production cell.
Smart Anti-Clog Micro-Grids
Hydro-dynamically optimized hole geometry maximizes water throughput while catching food particles as small as 1.5mm, safeguarding municipal sewer infrastructure.
