Detailed Manufacturing Process Flow

The production of expanded mesh is a highly specialized mechanical process, distinct from weaving or welding. It involves slitting and stretching solid metal sheets to create a continuous, homogenous mesh structure without any welds or interlocks. This unique process imparts superior strength and structural integrity.

1. Raw Material Selection: High-quality metal coils or sheets are chosen based on the desired final properties. Common materials include aluminum alloys (e.g., Al 3003, Al 5005 for facade applications due to their corrosion resistance and workability), stainless steel (e.g., AISI 304, 316L for harsh environments requiring superior corrosion resistance), and carbon steel. Each material is sourced from certified suppliers to ensure compliance with standards like ASTM B209 for aluminum or ASTM A240 for stainless steel.
2. Slitting and Expanding: The selected metal sheet is fed into an expanding machine. This machine simultaneously slits the metal and stretches it at regular intervals. This cold-forming process creates uniform, diamond-shaped openings. Unlike traditional cutting, no material is wasted, making it an economically efficient and environmentally friendly process. The tooling is precisely calibrated to achieve specific LWM, SWM, strand width, and thickness.
3. Flattening (Optional): Depending on the application, the mesh may undergo a flattening process. Expanded mesh in its original form is slightly raised at the strands. Flattening involves passing the mesh through a cold-roll reducing mill, which creates a smooth, uniform surface. This process is often preferred for aesthetic facade applications where a sleek, flush surface is desired.
4. Cutting and Fabrication: The expanded mesh is cut into required panel sizes and shapes using precision shears or CNC laser/plasma cutters. Custom fabrication, including bending, framing, and attachment point integration, is performed according to architectural drawings. Adherence to fabrication tolerances (e.g., ISO 2768-1) is critical.
5. Surface Treatment and Finishing: This is a crucial step for facade applications.
   • Anodizing (for Aluminum): Creates a durable, corrosion-resistant, and aesthetically pleasing oxide layer. Complies with ISO 7599 or MIL-A-8625F. Enhances service life significantly.
   • Powder Coating: Applied electrostatically and then cured under heat, providing a hard finish tougher than conventional paint. Offers a wide range of colors (RAL system) and excellent resistance to chipping, scratching, and fading. Conforms to AAMA 2603, 2604, or 2605 for architectural applications.
   • PVDF Coating: (Polyvinylidene Fluoride) A high-performance liquid coating offering superior color retention, chalk resistance, and UV stability. Ideal for extreme outdoor exposures. Meets AAMA 2605 requirements.
   • Hot-dip Galvanizing (for Steel): Provides a robust zinc coating for corrosion protection, compliant with ASTM A123.
6. Quality Control and Testing: Throughout the process, stringent quality control measures are implemented. This includes visual inspection for defects, dimensional checks (LWM, SWM, strand width/thickness), and adhesion tests for coatings (e.g., cross-hatch adhesion test for powder coating). Material certifications and test reports for mechanical properties (tensile strength, yield strength) are provided to ensure compliance with international standards (e.g., ISO 9001 certified manufacturing).

The typical service life of aluminum or stainless steel Diamond Expanded Mesh for Facade Screening with appropriate surface treatments (e.g., PVDF coating for aluminum) can exceed 30-50 years, even in challenging environmental conditions, demonstrating exceptional durability and low maintenance requirements.
