Epoxy Coated Wire Mesh

Epoxy-coated wire mesh is a woven wire mesh with a cured epoxy resin coating applied over the wire surface. The coating adds a protective barrier that improves corrosion resistance, helps withstand exposure to moisture and many industrial fluids, and extends service life in demanding operating environments.


For oil, hydraulic, and industrial filtration, epoxy-coated mesh is most often used as a support layer (also called a pleat support or pleat spacing layer) behind filter media. Lawrence Sintered Metals supplies epoxy-coated mesh that helps pleated filter elements hold their shape, resist collapse, and maintain consistent flow under pressure.

What Is Epoxy Coated Wire Mesh?

Epoxy-coated wire mesh starts as woven wire mesh (commonly stainless steel, carbon steel, or aluminum). After weaving, an epoxy resin is applied and cured to form a uniform protective layer over the wire surface.

 

Because the coating is designed to flex with woven wire, epoxy coatings are typically not applied to sintered-mesh laminates or rigid welded-mesh products, which serve different performance needs.

Why It Matters for Hydraulic Oil Filtration

Hydraulic systems rely on clean fluid to protect pumps, valves, cylinders, and precision components. In-line hydraulic filters and cartridge-style elements remove damaging particles from hydraulic oil as it circulates through equipment.

 

Epoxy-coated woven mesh is commonly selected as a support layer in pleated filter elements, especially in hydraulic oil filtration where strength, pleat stability, and corrosion resistance are required.

Common real-world use cases include:

 

  • Hydraulic filters on agricultural and farm equipment operating in wet, dirty, and highly variable conditions
  • Hydraulic filtration in industrial operations that run long hours and require stable flow and consistent filtration performance

Key Characteristics

  • Enhanced resistance to corrosion, moisture, and environmental exposure
  • Improved durability compared to uncoated woven mesh
  • Maintains flexibility for forming, cutting, and pleating
  • Performs well as a pleat support and spacing layer in filtration systems

Common Applications

Hydraulic Oil Filtration and Pleated Filter Support
Corrosion and Chemical Resistance
Screening and Protective Uses

Epoxy-coated wire mesh is used across industrial and commercial applications where surface protection and flexibility are critical.

Hydraulic Oil Filtration and Pleated Filter Support

One of the most common uses for epoxy-coated wire mesh is as a support layer in pleated filtration systems, including:

 

  • Hydraulic and oil filtration elements
  • Pleated filter assemblies where the media needs added structural support
  • Fluid filtration cartridges

 

In these assemblies, the epoxy coating helps protect the support mesh from corrosion while the woven structure provides the strength needed to support pleated media.

Corrosion and Chemical Resistance Applications

The combination of woven construction and protective coating makes epoxy-coated mesh suitable for:

 

  • Insect screening
  • Protective covers and guards
  • Light-duty barrier applications

Screening and Protective Uses

Epoxy-coated mesh is frequently used in environments where exposure to moisture, chemicals, or corrosive conditions may reduce the lifespan of uncoated wire, including:

 

  • Industrial ventilation and exhaust systems
  • Chemical processing and industrial equipment enclosures
  • HVAC and airflow applications

Materials and Base Alloys

Epoxy-coated wire mesh can be manufactured using various base materials depending on application requirements, including:

 

 

The base metal influences mechanical strength and temperature tolerance, while the epoxy coating adds surface protection and corrosion resistance.

How Epoxy Coated Mesh Differs from Other Mesh Types

Woven Wire Mesh

Woven wire mesh consists of interlaced wires forming a flexible, cloth-like structure. Epoxy coating is applied exclusively to this type of mesh due to its ability to flex, pleat, and form without cracking the coating.

Sintered Wire Mesh

Sintered wire mesh is produced by bonding multiple layers of woven mesh together using heat and pressure. This process creates a rigid, porous structure and does not involve epoxy coatings. Sintered mesh is selected for high-strength or precision filtration applications, not for coated flexibility.

Welded Wire Mesh

Welded wire mesh is formed by welding wires at their intersections, creating a rigid grid. Due to its construction, welded mesh is not typically epoxy-coated in the same manner as woven wire mesh and is used for entirely different applications.

Why Choose Lawrence Sintered Metals for Epoxy Coated Wire Mesh?

Epoxy-coated wire mesh is a strong fit when your application requires:

 

  • A woven mesh support with added corrosion resistance
  • Pleat support or pleat spacing behind filter media
  • Flexibility for forming or shaping
  • Extended service life in hydraulic, oil, and industrial filtration environments

 

Lawrence Sintered Metals supplies woven and coated mesh products and supports custom requirements when your filtration design demands a specific mesh count, wire diameter, or base alloy.

Custom Specifications and Support

Epoxy-coated wire mesh can be customized to meet specific requirements, including:

 

  • Mesh count and opening size
  • Wire diameter
  • Base alloy selection
  • Coating thickness and performance needs

 

Selection depends on operating environment, fluid exposure, temperature range, and the mechanical demands of the filter design. Our team can help confirm whether epoxy-coated woven mesh is the right support layer for your hydraulic oil filtration or industrial filtration application.

Frequently Asked Questions

No. Epoxy-coated wire mesh and sintered wire mesh are entirely different products. Epoxy coating is applied only to woven wire mesh. Sintered wire mesh is created by bonding multiple layers of woven mesh together using heat and pressure, and does not use epoxy coatings.
Epoxy-coated wire mesh is commonly used in filtration, HVAC systems, chemical processing, industrial screening, and protective applications. It is especially well-suited for environments where corrosion resistance and flexibility are required.
Epoxy-coated wire mesh is often used as a support layer in pleated filters because it maintains structural integrity while allowing flexibility for pleating. The epoxy coating helps protect the mesh from corrosion and wear, extending service life in air, oil, and fluid filtration systems.
Epoxy-coated wire mesh can be manufactured from several base materials, including stainless steel (such as 304 or 316L), carbon steel, and aluminum. The choice of base material depends on mechanical requirements, temperature exposure, and the operating environment.
Epoxy-coated wire mesh is typically used in moderate-temperature environments. While the base metal may tolerate higher temperatures, epoxy coatings have temperature limits. Application-specific temperature requirements should be reviewed during material selection.
Yes. The epoxy coating provides an additional protective barrier that helps resist corrosion, moisture, and environmental exposure. The level of corrosion resistance depends on the base material, coating thickness, and operating conditions.
Yes. Because it is woven, epoxy-coated wire mesh can be cut, formed, and shaped. Care should be taken during fabrication to avoid damaging the coating, especially at cut edges.
Selecting the correct mesh depends on the operating environment, filtration needs, temperature, chemical exposure, and mechanical requirements. Epoxy-coated woven mesh is best suited for applications that require flexibility, surface protection, and corrosion resistance without the need for sintered or welded construction.
