Technical Parameters and Specifications of Black Epoxy Coated Wire Mesh
Understanding the technical specifications of Black Epoxy Coated Wire Mesh is crucial for its optimal application. This product is typically manufactured from low carbon steel wire, galvanized iron wire, or even stainless steel wire, which then undergoes a specialized epoxy coating process. The black epoxy coating provides a durable, smooth, and aesthetically pleasing finish that offers superior protection against corrosion and abrasion.
Key Parameters:
- Material: Low Carbon Steel, Galvanized Steel, Stainless Steel (e.g., SS304, SS316). The base wire material determines the fundamental mechanical properties.
- Wire Diameter: Ranging from 0.4mm to 2.5mm, depending on the required strength and application. Measured in SWG (Standard Wire Gauge) or millimeters.
- Mesh Count (Mesh Per Inch): From 4 mesh to 60 mesh, indicating the number of openings per linear inch. Higher mesh counts mean finer filtration capabilities.
- Weaving Pattern: Plain weave, twill weave, Dutch weave, or welded mesh. Plain weave is the most common for its stability and straightforward construction.
- Coating Thickness: Typically 0.15mm to 0.3mm (150-300 microns), ensuring comprehensive coverage and enhanced protection. Thicker coatings generally offer superior corrosion resistance.
- Open Area: The percentage of open space in the mesh, influencing flow rate and filtration efficiency. Calculated based on wire diameter and mesh count.

The Meticulous Manufacturing Process of Black Epoxy Coated Wire Mesh
The superior performance of Black Epoxy Coated Wire Mesh is a direct result of a meticulously controlled manufacturing process. Unlike traditional casting or forging, wire mesh production involves wire drawing, weaving/welding, and then a sophisticated coating procedure. Here’s a detailed breakdown of the typical steps involved:
Process Flow Diagram (Conceptual Textual Representation):
1. Wire Material Selection & Drawing
High-quality raw wire coils (low carbon steel, galvanized steel, or stainless steel) are selected based on end-use requirements. These wires are then drawn through a series of dies to achieve the precise desired wire diameter.
↓
2. Weaving or Welding
The drawn wires are then fed into automated weaving looms or welding machines. For woven mesh, warp and weft wires are interlaced to form the desired mesh pattern (e.g., plain weave). For welded mesh, wires are precisely resistance-welded at their intersections, creating a rigid structure.
↓
3. Surface Preparation (Cleaning & Pre-treatment)
This is a critical stage for coating adhesion. The woven or welded mesh undergoes thorough cleaning, typically involving degreasing, acid pickling to remove rust and scale, and rinsing. This is followed by a phosphating or chromate conversion coating to create an ideal surface for epoxy adhesion. Proper surface preparation ensures maximum bond strength and long-term durability of the coating.
↓
4. Electrostatic Powder Coating (Epoxy Application)
The prepared mesh is then moved to an electrostatic powder coating booth. Finely ground epoxy powder particles are electrostatically charged and sprayed onto the grounded mesh. The electrostatic attraction ensures a uniform and comprehensive coating, even on complex mesh geometries. This method minimizes waste and ensures excellent coverage.
↓
5. Curing (Baking)
After powder application, the coated mesh enters a high-temperature curing oven. The heat melts the epoxy powder, causing it to flow out and form a continuous, smooth, and highly durable film that bonds strongly to the wire surface. The curing temperature and duration are precisely controlled to achieve optimal coating properties.
↓
6. Cooling & Quality Control
The mesh exits the oven and is allowed to cool. Comprehensive quality control checks are performed, including visual inspection for coating uniformity, adhesion tests (e.g., cross-hatch test, bend test), coating thickness measurement (using magnetic or eddy current gauges), and occasionally salt spray tests for corrosion resistance (per standards like ASTM B117 or ISO 9227). Compliance with international standards such as ISO 9001 for quality management is strictly adhered to, ensuring a consistent and reliable product.
↓
7. Packaging & Dispatch
Finally, the inspected and approved Black Epoxy Coated Wire Mesh is carefully rolled or cut into sheets, then packaged to prevent damage during transit, ready for shipment to clients worldwide.
This detailed process ensures that each batch of Black Epoxy Coated Wire Mesh meets stringent quality specifications and delivers exceptional performance in its intended application.
