company news about Production Process Of Expanded Metal Mesh

  Expanded metal mesh, a versatile and durable material, is widely used in construction, industrial safety, filtration, and decorative applications. Its unique lattice structure combines strength with lightweight properties, making it ideal for diverse environments. Below is a detailed introduction to its production process, material characteristics, and key applications.

1. Material Selection

The production begins with high-quality metal sheets, commonly made from:

Low-carbon steel: Known for its balance of strength and cost-effectiveness, often galvanized or coated for corrosion resistance.

Stainless steel: Preferred for harsh environments due to superior rust resistance (e.g., grades 304 or 316).

Aluminum or copper: Used in lightweight or decorative applications.

The thickness of the metal sheet typically ranges from 0.5 mm to 8 mm, depending on the intended use (e.g., lightweight mesh for filters vs. heavy-duty mesh for industrial platforms).

2. Production Process

(1). Slitting And Stretching

Slitting: Metal sheets are fed into an expanding machine, where parallel blades make staggered slits across the surface.

Stretching: Hydraulic or mechanical pressure stretches the slitted sheet, forming diamond-shaped or hexagonal openings. This process increases the sheet's surface area by up to 10 times while maintaining structural integrity.

(2). Pressing And Flattening

After stretching, the mesh passes through rollers to flatten protruding edges, ensuring a uniform thickness and smooth surface. This step enhances load-bearing capacity and safety.

(3). Cutting And Shaping

The expanded mesh is cut into panels or rolls using laser cutting, shearing, or CNC machines. Custom shapes (e.g., curved edges) can be created for architectural or design purposes.

3. Surface Treatment

To improve durability and aesthetics, the mesh undergoes one or more treatments:

Galvanizing: Hot-dip or electroplated zinc coating prevents rust, ideal for outdoor use.

PVC coating: A layer of polyvinyl chloride adds weather resistance and color options (e.g., green for landscaping).

Powder coating: Provides a decorative finish while protecting against UV rays and chemicals.

Anodizing (for aluminum): Enhances corrosion resistance and allows for metallic color finishes.

4. Quality Control

Manufacturers adhere to strict standards (e.g., ISO 9001) to ensure product reliability.

Key tests include:

Tensile strength tests: Verify load-bearing capacity (up to 500–800 MPa for heavy-duty mesh).

Salt spray testing: Evaluates corrosion resistance over extended periods.

Dimensional checks: Ensure consistent mesh size (common openings range from 1/4" to 4")
