Wholesale Sink Drain Strainer Manufacturer & Factories

JANA Plumbing manufactures an extensive portfolio of professional solid brass and austenitic stainless steel sanitary components. Our primary catalog lines encompass kitchen sink basket strainers, bar sink strainers, spin-lock and post-style strainers, disposer flange & stopper sets, commercial lavatory pop-up assemblies, grid strainers, bath drains, shower drains, replacement drain components, heavy-duty closet flanges, toilet tank flush levers, shower arms & escutcheon flanges, sink protector bottom grids, stainless braided flexible hoses, dielectric unions, and brass pipe fittings.

Our products are certified by IAPMO R&T under active Uniform Plumbing Code (UPC) and Canadian Uniform Plumbing Code (cUPC) listings (including Certificate Numbers 6229, 8175, 12307, N-11587, and T-11586). They comply fully with standards developed by ASME (ASME A112.18.2), CSA (CSA B125.2), and NSF. Furthermore, our brass components meet the California AB1953 lead-free mandate and NSF/ANSI 372 standards (<0.25% lead content). Factory operations are audited under ISO 9001:2015 quality management and BRC global consumer safety frameworks.

Our dual-origin infrastructure provides supply-chain resilience and tariff flexibility. While our Yuhuan headquarters provides decades of tooling expertise and extensive brass-casting capacity, our 14,400 m² automated facility in Kabinburi Industrial Zone, Thailand (operational since December 2023) allows buyers to source products with qualifying Country of Origin (COO) status outside Section 301 tariffs. Both facilities run unified ISO 9001 quality procedures, shared progressive tooling, and standardized raw material checks.

We provide full turnkey OEM/ODM engineering support. Our engineers fabricate custom stamping dies, hydraulic forming molds, and machining programs directly from 2D blueprints (DWG, PDF) or 3D CAD models (STEP, IGES). On the packaging side, we offer custom-branded four-color retail blister cards, high-impact clamshells, contractor bulk master cartons, laser-etched SKU logos, bespoke barcode labeling (UPC-A/EAN-13), and multilingual contractor instruction inserts.

For standard catalog SKUs with regular chrome or polished brass finishes, our MOQ typically starts at 500 to 1,000 units per item. For specialized PVD finishes (Matte Black, Brushed Bronze, Satin Nickel) or fully customized cast brass bodies requiring dedicated tooling, the typical opening MOQ is 2,000 units. Standard production lead times average 30 to 45 days after deposit confirmation and sample approval, with expedited 25-day replenishment schedules available for repeat container-load contracts.

Every production lot undergoes a multi-gate QC regimen: (1) Spectral verification of raw ingot metallurgy for copper, zinc, and lead content; (2) Thread pitch and diameter verification using precision go/no-go optical gauges; (3) 100% pneumatic pressure testing under water at 0.35 MPa to verify zero air porosity across castings and joints; (4) Neutral salt spray testing (ASTM B117) for 96 to 200+ hours to ensure finish corrosion resistance; and (5) Drop-test verification of packed master cartons according to ISTA-1A standards.
