What is epoxy coated wire mesh made of?

The core is woven wire cloth or a welded grid in low-carbon steel (Q195/Q235 class) or aluminum alloy (5052/5154 class). The coating is a thermoset epoxy powder that cures into a continuous film. Steel cores give strength and economy; aluminum cores give light weight and corrosion resistance for screens.

How is the epoxy coating applied?

Three routes are common: electrostatic powder spraying, where charged powder is fused onto the wire; fluidized bed dipping, where preheated wire picks up a thicker powder build; and electrophoretic (e-coat) application from an aqueous bath. All routes are oven-cured to fuse and cross-link the film.

What is the difference between epoxy coated and PVC coated wire mesh?

Epoxy mesh forms a thin hard thermoset film (30-80 micron) that resists oils, solvents, and temperatures up to roughly 120-150 C. PVC forms a thick soft plastic jacket (0.4-0.8 mm) that suits fencing and color work but softens above about 60 C and degrades in some solvents. Epoxy is the standard for filtration and screens; PVC is the standard for coated fencing.

How thick is the epoxy coating?

Typical film thickness is 30-80 micron after curing. Fine woven screens use thinner films to keep openings open; welded guards and heavy screening use thicker builds. State the target film thickness in the RFQ and verify it on arrival.

Is epoxy mesh good for filter elements?

Yes. Epoxy mesh is widely used as the inner support layer of pleated hydraulic, lube, fuel, and air filter elements. The hard film resists the fluid while the woven structure holds pleat geometry and keeps pressure drop low. Counts from 30 x 30 to 100 x 100 cover typical backing grades.

What mesh counts are available?

Epoxy mesh cloth runs from about 14 mesh to 100 mesh, covering insect screens, grilles, and filter backing. Welded epoxy mesh starts around 1/2 in opening for guards and enclosures. Counts outside stock ranges are produced on request.

Which colors are available?

Black and gray are the standard stock colors for epoxy mesh. White and custom RAL colors are available on request, usually with a minimum order quantity. Always specify the color reference, not just a color name.

Does epoxy coated wire mesh rust?

The epoxy film blocks moisture, so coated mesh resists rust far better than bare steel in the same environment. Rust only starts where the film is damaged: scratches, cut edges, and over-tight bends. Sealing cut edges and avoiding sharp folds keeps steel-core mesh sound for years.

Can epoxy mesh be welded or cut after coating?

Cutting is fine with snips, a guillotine, or a fine-tooth saw, followed by touch-up of the exposed edge. Welding after coating destroys the film around the joint and releases fumes, so weld first and coat after, or use mechanical fasteners instead.

How heat resistant is the epoxy film?

Cured thermoset epoxy film is rated for continuous service to roughly 120-150 C depending on the compound, far above PVC or PE coatings. Confirm the compound rating in the RFQ for high-temperature filter or process duty.

How long does epoxy coated wire mesh last?

Indoors and in filter elements, quality epoxy mesh can last the life of the equipment with routine washing. Outdoors, black and gray epoxy screens typically serve many years in mild and coastal climates when the core material is chosen for the site; steel cores benefit from sealed edges and galvanized options.

How do I verify the coating quality on arrival?

Measure epoxy mesh film thickness with a coating thickness gauge at several points, bend a sample wire 180 degrees to check adhesion, inspect for pinholes and bare spots under magnification, and compare color against the approved swatch. Request film thickness and adhesion certificates with the shipment.

What affects the price of epoxy mesh?

Price moves with mesh count, wire diameter, core material (aluminum costs more than steel), film thickness, color (custom RAL costs more than stock black or gray), construction, quantity, and certification needs. Steel and resin markets also shift quotes. Share the full specification for an itemized quote.

What are the typical roll sizes and lead times?

Rolls run 0.9-1.5 m wide by 15-30 m long; sheets and cut pieces are sized to the project. Standard grades in black and gray ship from stock programs in days, while custom colors and heavier builds typically need 2-4 weeks. State your target date for a confirmed schedule.

Can I get a sample before ordering?

Yes. Request a sample of the exact construction, mesh count, wire diameter, and color to confirm finish, opening, and adhesion before bulk production. Stock colors ship quickly; custom color orders may carry a small sampling charge credited against the order.

Epoxy Mesh Coating and Specification Guide

Epoxy mesh starts with a woven wire cloth or welded grid, then receives a thermoset epoxy coating: powder is applied by electrostatic spray or fluidized bed and oven-cured at 180-200 C, fusing into a continuous 30-80 micron film. The core wire is low-carbon steel (Q195/Q235 class) for strength and economy, or aluminum alloy (5052/5154 class) for lightweight screens. State mesh count, wire diameter, opening, core material, coating color and film thickness, form, and quantity in every RFQ. Epoxy mesh specifications combine woven geometry with film properties, so both the mesh numbers and the coating numbers belong in the RFQ.

Applications

Where Epoxy Mesh Is Used

Choose epoxy mesh when the part must resist oil, moisture, and abrasion while keeping consistent openings and a clean finish.

Hydraulic and air filter support

Epoxy mesh forms the inner support layer of pleated filter elements, holding pleat geometry while oil or air flows through without blocking.

Window and insect screens

Fine epoxy coated aluminum mesh keeps insects out while resisting corrosion and cleaning easily with water.

Speaker and appliance grilles

Black epoxy mesh covers speakers and appliances with a consistent acoustic mesh that shrugs off fingerprints and humidity.

Particle grading and sifting

Epoxy coated cloth supports grading screens and protects finer sieve layers in multi-deck separation machines.

Automotive and mobile filtration

Fuel, oil, and air filter elements in vehicles use epoxy coated support mesh for pleat stability and chemical resistance.

Industrial guarding and screening

Epoxy coated welded mesh panels shield machinery and secure openings with a tough, non-glare finish.

How to choose

How to Select the Right Epoxy Mesh

Start from the application, then fix the epoxy mesh core wire, mesh count, film thickness, color, and verification. A complete RFQ avoids assumptions and re-quotes.

Start from the application

Filter backing needs fine counts and uniform openings; screens need strength and appearance; guards need heavy wire and a thick film build.

Choose the core wire

Aluminum alloy keeps screens light and corrosion resistant; low-carbon steel adds strength and lowers cost. Name the core material in the RFQ.

Mesh count and wire diameter together

The count decides what passes, the wire diameter decides strength and open area. State both numbers, never count alone.

Film thickness vs flexibility

Thicker films resist wear but can crack at tight bends. Flexible screens need a thin film; guards and heavy screening need a thick build.

Fix the color with a reference

Black and gray run in stock programs. Custom colors produce in batch lots, so quote against a RAL code and approve a swatch before bulk.

Plan for cut edges

Cut edges expose the core wire. Order touch-up epoxy or edge trim with cut pieces so corrosion does not start at the frame line.

By form

Rolls suit continuous screening runs; sheets and cut pieces suit panels and grilles; welded panels suit guarding and enclosures.

Verify with a sample

Request a sample of the exact count, wire, and color before bulk. Check adhesion with a 180-degree bend and film thickness with a gauge.

Common buying mistakes

Epoxy Mesh Buying Mistakes to Avoid

Six epoxy mesh buying errors that shorten service life or trigger rejection disputes. Each one is avoidable at the RFQ stage.

Specifying epoxy coated without film thickness

A thin or uneven film exposes wire at wear points and cut edges. State 30-80 micron targets and verify on arrival.

Ignoring the core material

Steel and aluminum cores behave differently under corrosion and weight loads. An unnamed core invites the factory to choose the cheapest.

Ordering screens by mesh count alone

The same count with a thicker wire gives a smaller opening and less open area. Always pair count with wire diameter.

Confusing epoxy with PVC coating

The two films differ in thickness, flexibility, temperature range, and oil resistance. Quotes that look cheap may be PVC in disguise.

Leaving cut edges unprotected

Cut edges expose bare core wire and corrode first. Order touch-up compound or edge trim with every cut-to-size piece.

Skipping the adhesion check

A 180-degree bend test on arrival catches flaking film that no paperwork can justify. Require the check in the RFQ.

Buyer benefits

Why Buyers Choose Epoxy Mesh

Epoxy mesh pairs a hard fused film with consistent woven openings: chemical resistance and clean appearance at a fraction of stainless cost.

Oil and solvent resistant film

The cured epoxy film resists petroleum fluids, mild acids, and alkalis, which is why filter elements rely on it as support mesh.

Cost-effective vs stainless

Coated steel and aluminum wire deliver corrosion resistance at a fraction of stainless steel wire cloth cost, which keeps epoxy mesh the economical choice for screens and filter backing.

Long, low-maintenance service

A quality film over the right core runs for years in screens and filter elements with nothing but routine washing.

Consistent openings for filtration

Woven construction and controlled coating keep epoxy mesh openings uniform, so pleating, airflow, and separation behave predictably.

Clean, uniform appearance

Black and gray epoxy finishes read professional on grilles, guards, and screens, and hide handling marks better than bright metal.

Fast turnaround on stock grades

Standard counts, colors, and roll widths ship from stock programs in days; custom colors and builds follow in weeks.

Protect the film. Cut cleanly, seal edges, and form without sharp creases for a long, neat service life.

Handling and installation

Working with Epoxy Mesh

Cut with shears, not heat

Use aviation snips, a guillotine, or a fine-tooth saw to cut epoxy mesh. Torches and grinding discs burn the epoxy film back from the cut and expose the core.

Seal every cut edge

Touch up exposed ends with matching epoxy paint or trim with an edge channel so moisture cannot climb the bare wire.

Form without sharp creases

Tight folds crack the film. Use a radius of at least a few wire diameters at bends, and tension evenly when fitting screens.

Clean with mild detergents

Rinse with water and wipe with mild detergent. Avoid solvent cleaners and abrasive pads, which dull or strip the film.

Packing and delivery

Epoxy Mesh Packing for Export

Packing protects the epoxy mesh finish, keeps rolls round and sheets flat, and preserves traceability through transit and receiving inspection.

Rolls wrapped and banded

Rolls ship in waterproof film and woven bags, stood on pallets with protected ends so the coating never scuffs during handling.

Flat packing for sheets

Sheets and cut pieces pack flat on pallets or in plywood cases with interleaving paper and corner protection.

Edge and corner protection

Every bundle carries corner guards and strapping that never bears directly on the coated surface.

Label by count and color

Each bundle lists construction, mesh count, wire diameter, core material, color, film thickness, dimensions, and quantity.

Certificates and inspection

Film thickness and adhesion certificates accompany the shipment when requested. Pre-shipment inspection by SGS, BV, or TÜV is available on request.
