A stainless steel mesh basket is a cylindrical or box-shaped filtration component made from woven wire mesh, welded at seams and fitted with handles, rims, or flange mounts. Industrial buyers use these baskets for solid-liquid separation, particle retention, and media support in chemical reactors, food processing lines, and pharmaceutical tanks. When you need a filter basket manufacturer who can produce custom sizes, weld patterns, and mesh specifications to your drawing, buying direct from an Anping factory gives you full control over geometry, material, and finish.
At ANPING MAOYE, we manufacture custom wire mesh baskets in 304, 316L, and 904L stainless steel for clients in water treatment, oil refining, food processing, and chemical manufacturing. Every basket is cut, formed, welded, and polished in our Anping facility. We do not resell stock baskets — we build to your specification.
What Is a Stainless Steel Mesh Basket?
A stainless steel mesh basket is a rigid or semi-rigid container formed from woven wire mesh sheets. The mesh panels are cut to shape, rolled or folded into the desired profile, and joined by TIG welding, spot welding, or brazing. Common configurations include:
- Cylindrical baskets — used as strainer elements inside pipeline housings
- Rectangular baskets — inserted into tank manways for batch filtration
- Conical baskets — fitted to filter housings with tapered seats
- Pleated baskets — increased surface area for high-flow applications
- Multi-layer baskets — coarse outer mesh protects fine inner mesh
The basket design must match the housing geometry, flow rate, and particle load of the application. A poorly specified basket collapses under differential pressure, allows bypass flow around the rim, or corrodes in acidic media. That is why buyers source from a basket strainer supplier with in-house engineering and welding capability rather than buying generic stock items.
Industrial Applications for Wire Mesh Filter Baskets
| Industry | Application | Typical Material | Mesh Range |
|---|---|---|---|
| Chemical processing | Catalyst recovery, resin filtration | 316L | 20–200 mesh |
| Food & beverage | Cooking oil filtration, sugar syrup straining | 304, 316L | 40–150 mesh |
| Pharmaceutical | API slurry filtration, WFI systems | 316L, electropolished | 100–400 mesh |
| Water treatment | Intake screening, sediment removal | 304, 316L | 10–80 mesh |
| Oil & gas | Produced water filtration, downstream refining | 316L, 2205 Duplex | 60–250 mesh |
| Mining | Tailings dewatering, process water recycling | 304, 316L | 20–100 mesh |
For buyers who need filtration across multiple stages, mesh baskets can be paired with filter discs and cylindrical cartridges in a multi-stage system.
Why Buy Custom Wire Mesh Baskets from a Manufacturer?
Stock baskets from catalog suppliers rarely match the exact dimensions, flange pattern, or mesh specification of industrial equipment. Buying custom wire mesh baskets direct from a manufacturer solves these problems.
Exact Fit to Your Housing
We build baskets to your housing drawing or sample. Critical dimensions we control include:
- Outer diameter — tolerance ±0.5 mm for slip-fit or press-fit installation
- Overall height — including handle clearance and flange thickness
- Mesh aperture — matched to your particle retention target
- Wire diameter — thicker wire for structural strength, thinner wire for open area
- Rim and flange style — flat rim, rolled rim, bolted flange, or clamp groove
- Handle configuration — bail handle, lift lugs, or integrated tabs
Material Selection for Corrosion Resistance
| Grade | Key Alloys | Best For | Relative Cost |
|---|---|---|---|
| 304 | 18% Cr, 8% Ni | Food processing, water treatment, mild chemicals | Baseline |
| 316L | 16% Cr, 10% Ni, 2% Mo | Chloride exposure, pharmaceutical, marine | +25–35% |
| 904L | 20% Cr, 25% Ni, 4.5% Mo | Aggressive acids, sulfuric environments | +80–120% |
| 2205 Duplex | 22% Cr, 5% Ni, 3% Mo | High-pressure, high-chloride oil & gas | +60–90% |

Welding and Finish Quality
Basket seams must withstand cyclic pressure and thermal shock. Our welding protocols include:
- TIG welding for circumferential seams on cylindrical baskets
- Spot welding for grid-style box baskets with reinforced corners
- Electropolishing for pharmaceutical and food-grade surfaces (Ra < 0.8 μm)
- Passivation after welding to restore chromium oxide layer
- Leak testing at 1.5× operating pressure for critical applications
Manufacturing Process: From Mesh Sheet to Finished Basket
- Mesh selection — We choose the correct mesh count, wire diameter, and material grade based on your filtration target and chemical environment.
- Blanking — CNC laser or punch press cuts mesh sheets to the unfolded basket pattern.
- Forming — Hydraulic presses roll cylindrical sections or brake-press fold rectangular panels.
- Welding — TIG or spot welding joins seams, handles, and reinforcement rings.
- Inspection — Dimensional checks, weld penetration testing, and mesh integrity verification.
- Finishing — Electropolishing, passivation, or surface coating as specified.
- Packing — Individual PE bags, foam separators, and wooden crates for export.
Standard lead time for custom wire mesh baskets is 3–5 weeks. Repeat orders with approved drawings ship in 2–3 weeks.

FAQ: Custom Stainless Steel Mesh Baskets
What is the minimum order quantity for custom mesh baskets?
Prototype orders start at 1–5 pieces. Production MOQ is typically 50 pieces for standard mesh specifications and 100 pieces for custom mesh counts or non-standard materials.
Can you build baskets to my existing drawing or sample?
Yes. Send us a CAD drawing, PDF dimensioned sketch, or a physical sample. Our engineering team reviews fit, weld access, and mesh orientation before quoting. We can also reverse-engineer from a worn or damaged sample.
What is the difference between a mesh basket and a sintered filter?
A mesh basket is a formed wire-mesh container with visible apertures. A sintered filter is a bonded metal-fiber or metal-powder medium with no visible weave. Mesh baskets are reusable, cleanable, and suited for coarse-to-medium filtration (10–500 μm). Sintered filters handle finer ratings (1–100 μm) and higher pressures but are typically disposable or require specialist cleaning. For a detailed comparison, see our sintered mesh vs woven mesh guide.
Do you provide material test certificates?
Every batch ships with a mill test certificate (MTC) showing chemical composition and mechanical properties. Third-party testing by SGS, Bureau Veritas, or TÜV can be arranged for qualified orders.
What is the typical lifespan of a stainless steel mesh basket?
In clean chemical service with proper handling, 304 and 316L baskets last 3–5 years. In abrasive or high-cycle applications, lifespan may be 1–2 years. We stock replacement mesh inserts so you can rebuild existing basket frames rather than replacing the entire unit. For maintenance guidance, see our stainless steel mesh lifespan guide.
Can you add reinforcement to prevent basket collapse?
Yes. We can add internal support rings, longitudinal ribs, or external bands to increase pressure rating. Reinforced baskets typically withstand 5–10 bar differential pressure depending on mesh fineness and basket diameter.
What electropolishing standards do you meet?
Our electropolished 316L baskets meet Ra < 0.8 μm surface roughness, suitable for pharmaceutical and food-grade applications. We can provide surface-roughness test reports on request.
