Engineered Sink Strainers & Plumbing Assemblies
High-precision economy and heavy-duty sink basket strainers manufactured to ASME A112.18.2/CSA B125.2 and cUPC plumbing codes.
The China Manufacturing Paradigm for Economy Strainers
In global procurement, "Economy Strainer" does not imply compromised durability; it defines peak metallurgical efficiency, progressive stamping mastery, and vertical integration.
Yuhuan Industrial Cluster Precision
Situated in Yuhuan, Zhejiang—China's recognized valve and sanitary plumbing capital—our facilities benefit from complete supply-chain proximity. From high-grade brass ingot refineries to cold-rolled stainless steel strip mills, raw material latency is reduced to hours rather than weeks.
- Direct access to CW617N, C37700, and SS304/SS201 alloys
- Sub-tier mold tooling ecosystems yielding tooling turnaround in <14 days
- Deep cluster cost efficiencies pass directly to wholesale landed margins
Automated Progressive Stamping
Our economy line optimizes material yield up to 92% utilizing high-speed multi-stage transfer presses. By integrating hydraulic drawing, basket flanging, and slot perforations in a single pass, labor intensity per unit drops drastically.
- Manipulator robots ensuring continuous basket extraction
- Zero-defect robotic thread cutting on sink locknuts and slip-joints
- Burr-free edge finishing eliminating manual deburring stages
Thailand Dual-Hub Origin Security
Recognizing the volatile global trade environment, JANA established Gateway Enterprise Corporation in Kabinburi, Thailand (14,400 m²). This facility provides North American importers with zero anti-dumping risk and tariff diversification.
- Full Country-of-Origin (COO) documentation compliance
- Mirror tooling setups between China and Thailand operations
- Uninterrupted supply security during regional disruptions

Localized Application Scenarios & Sector Solutions
Economy strainers serve distinct operational functions across residential high-rises, commercial modular housing, and recreational vehicle manufacturing.
Multi-Family & High-Density Housing
Large-scale residential developments demand repeatable, leak-free assemblies that balance tight budget caps with zero warranty callback thresholds. Our JN-1012 Quick-Connect models eliminate tool slippage in cramped under-sink cabinets.
- Tool-less hand-tight installation nuts reducing labor hours by 40%
- Self-centering conical washers that seal without plumbers putty
- Standard 3-1/2" diameter fitting all major North American stainless sinks
RV & Manufactured Modular Homes
Recreational vehicles and pre-fabricated homes operate under continuous vibrational stress and structural flexing during transit. Rigid cast components can fail or crack thin sink bowls under torsional dynamic strain.
- Lightweight stamped stainless bodies preventing basin fatigue
- Deep-cup stick post baskets (JN-1014) staying locked over rough terrain
- Shallow clearance depth compatible with compact under-counter drawers
Wholesale Private Label & Retail Packaging
Big-box home improvement centers and specialty plumbing wholesale distributors need custom branded, shelf-ready kits that maximize turnover rates and minimize SKU return rates.
- Full private label barcoding, blister packaging, and master-carton labeling
- Comprehensive kit bundling: Strainer + Tailpiece + Gasket sets
- Electrophoretic and PVD finishes: Matte Black, Brushed Nickel, and Chrome
Future-Proofing Sanitary Ware Manufacturing (2025–2030)
How regulatory pivots, digital inventory replenishment, and metallurgical innovation are transforming economy drainage products globally.
Lead-Free Legislation
Global adoption of zero-lead plumbing acts (NSF 372 / California AB1953) is pushing manufacturers away from cheap zinc-alloy castings toward high-purity stamped austenitic steel or bismuth-refined brass.
Robotic Polishing & PVD
Modern consumers demand luxury aesthetics at economy price tiers. Six-axis robotic polishing cells now prep stamped components for physical vapor deposition (PVD), giving economy units 10-year surface warranties.
Nearshoring & "China+1"
Supply chain shocks have made multi-regional fulfillment mandatory. Dual-facility setups in Zhejiang and Kabinburi offer international brand managers tariff insulation without having to qualify multiple vendors.
Lifecycle Decarbonization
Using 100% recyclable post-industrial stamping scrap directly in integrated melting crucibles cuts virgin extraction energy by 60%, answering global ESG procurement mandates.
Frequently Asked Questions for B2B Sourcing
Essential technical, logistics, and certification clarity for plumbing procurement directors.
How does an Economy Strainer differ from Heavy-Duty Brass models?
Economy strainers primarily utilize stamped stainless steel (AISI 304 or 201) or lightweight brass shells with threaded die-cast or ABS locknuts. Heavy-duty units (like our JN-1001 series) feature solid cast or forged brass bodies. Both comply with ASME A112.18.2 flow rate and leak resistance standards, but economy lines offer significant unit weight and cost reductions ideal for high-volume commercial turns.
What testing procedures are applied to assure zero-leak integrity?
Every production batch undergoes hydrostatic head testing at 15 PSI, gasket compression testing across thermal cycling (-10°C to +85°C), and automated thread gauge verification (Go/No-Go thread pitch inspection). This guarantees leak-free slip-joint union connections with standard North American 1-1/2" plastic or brass tailpieces.
What are the minimum order quantities (MOQ) and production lead times?
Standard catalog SKUs carry an MOQ of 1,000 units per line item, with master carton OEM packaging starting at 2,500 units. Initial production runs for custom-branded stampings require 30 to 45 days for tooling and sample verification; repeat container-load orders typically dispatch in 20 to 25 days from either China or Thailand port facilities.
Can you facilitate dual-origin billing and logistics split-shipments?
Yes. JANA operates integrated enterprise resource planning across our Yuhuan headquarters and Kabinburi facility. Enterprise clients can allocate container quantities across origins based on geographic import tariffs, transit times, and regional landed-cost modeling without having to renegotiate contract terms or re-test product SKUs.
