Product Overview – Stainless Steel Sink Strainers & Sieves

Stainless steel sink strainers are precision-stamped drainage components designed to prevent solid debris, food particles, and fibrous material from entering drain lines. Manufactured using deep drawing, perforating, and edge-rolling processes on SS sheet metal, these parts combine mechanical durability with hygiene compliance for use in food processing, laboratory, hospital, and commercial kitchen environments.

Sink Drain Strainers & Basket Strainers

Sink drain strainers, basket-type sink strainers, cup strainers, and kitchen drain catchers are press-formed from SS 304 or SS 316 sheets. Standard sizes range from 3-1/2″ to 4-1/4″ diameter. Available with perforated base, cross-bar base, or slotted base. Suitable for undermount sinks, drop-in sinks, and commercial kitchen sinks. Variants include stopper-type sink strainers, twist-and-lock drain strainers, and removable sink basket inserts.

Perforated Sink Sieves & Hair Catcher Strainers

Flat perforated sink sieves, shower floor sieves, bathroom floor drain sieves, and hair catcher strainers are stamped from SS 304 and SS 316 sheets with hole diameters from 1 mm to 8 mm. Used in bathroom floor drains, laboratory sinks, laundry drains, and industrial wash stations. Fine-mesh sieve inserts and coarse-screen strainer variants are both available depending on filtration requirement.

Stainless Steel Floor Drain Strainers & Gully Strainers

Square and rectangular SS floor drain strainers, gully trap strainers, channel drain sieves, and linear drain grates are deep-drawn or press-bent from SS 304/316 sheets. Designed for heavy foot traffic in food processing plants, pharmaceutical facilities, hospitals, and commercial kitchens. Available with anti-slip pressed patterns, flanged edges, and welded legs for stable positioning in drain bodies.

OEM Custom-Pressed Sink Components

For OEM customers, we manufacture custom sink strainer assemblies, tailpiece strainers, overflow ring assemblies, and pressed sink components to buyer-supplied drawings and specifications. Tooling is developed in-house for consistent part-to-part repeatability. Minimum order quantities apply for custom tooling development. Export packaging with ISPM-15 compliant crating is available for international buyers.

Waste Basket Strainer Assemblies & Drain Kits

Complete stainless steel waste drain assemblies, sink basket strainer kits, P-trap connection strainers, and pressed drain body components are assembled with rubber gaskets, friction rings, and brass locknut hardware. These assemblies are ready for direct installation and supplied to sanitary ware manufacturers, plumbing product distributors, and contractor supply chains.

Corrosion Resistance & Hygiene

SS 304 (18/8 chromium-nickel) and SS 316 (with 2–3% molybdenum addition) provide superior resistance to chloride pitting, crevice corrosion, and biological fouling. Electropolished or passivated surfaces meet FDA, NSF 61, and 3-A Sanitary Standards for food and beverage contact. Tested per ASTM A262 for intergranular corrosion resistance.

Dimensional Accuracy & Tooling Consistency

Progressive die tooling and hydraulic presses maintain ±0.1 mm dimensional tolerances across production runs. CNC-punched perforations ensure consistent hole pitch, diameter, and open-area percentage. Each batch is inspected against master gauges and first-article inspection reports are available for OEM qualification.

Custom Perforation Patterns

Round hole, slotted, hexagonal, square, and decorative perforation patterns are available. Open area percentages range from 20% to 65% depending on straining duty. Laser perforation available for ultra-fine sieves with hole diameters below 0.5 mm. Combination of deep-drawn body with flat perforated disc insert is a popular OEM configuration.

Surface Finish Options

Available in mill finish (2B), bright annealed (BA), No.4 satin/brushed, No.8 mirror polish, and bead-blast matte finishes. Passivation per ASTM A967 is standard for food-grade and medical-grade parts. Electropolishing available for pharmaceutical and biotech applications requiring Ra < 0.4 μm surface roughness.

Export Packaging & Documentation

Products are individually wrapped, bulk-packed in cartons, and palletized for sea or air freight. Mill Test Certificates (MTC) per EN 10204 3.1, dimensional inspection reports, and packing lists are supplied with each shipment. ISPM-15 fumigated wooden crating available for FCL and LCL container exports.

Manufacturing Process

Raw SS coil/sheet material is procured with mill test certificates. Blanking dies cut circular or rectangular blanks from sheet. Deep drawing presses form the cup/basket shape in single or multi-stage operations. Perforating presses create hole patterns using precision punch-die sets. Edge trimming and flanging complete the profile. Post-forming operations include deburring, passivation, and surface finishing. 100% dimensional verification is performed prior to packing. Traceability is maintained through heat number tracking from mill cert to finished part.
