Process Flow Diagram: Expanded Steel Mesh Manufacturing

1. Material Selection & Preparation: High-grade steel coils (e.g., Q235, Q195) are selected based on desired strength and ductility. For corrosion resistance, pre-galvanized or cold-rolled steel is often chosen. The material thickness, often around 0.2mm (or related to a 0.2 gauge, depending on the specific product interpretation of '.2'), is critical here.
2. Slitting: The large steel coils are precisely slit into narrower strips according to the desired final mesh width and pattern.
3. Expanding (Stamping/Slitting & Stretching): This is the core process for expanded mesh. The steel strip is simultaneously slit and stretched through a specialized expanding machine. This creates a continuous, joint-free mesh pattern, typically diamond-shaped, without any material loss. The precise settings of the machine determine the LWD (Long Way of Diamond), SWD (Short Way of Diamond), strand width, and strand thickness, which collectively define the .2 steel mesh characteristics.
4. Flattening (Optional): For specific applications requiring a smoother surface, the expanded mesh can be cold-rolled to flatten the strands, resulting in a smooth, flat surface. This process increases rigidity.
5. Shearing/Cutting: The continuous expanded mesh is cut into panels of specified dimensions.
6. Surface Treatment: For galvanized steel mesh, this step is crucial for corrosion resistance.
   • Hot-dip Galvanization: The mesh is immersed in molten zinc, forming a metallurgical bond that provides superior protection. This is common for anti-throwing fences.
   • Electro-galvanization: A thinner zinc coating applied via an electrolytic process, offering a smoother finish.
   • Powder Coating: An additional layer for enhanced aesthetics, UV resistance, and further corrosion protection, often applied over galvanized mesh.
7. Quality Control & Testing: Each batch undergoes rigorous testing to ensure compliance with international standards such as ISO 9001 (Quality Management), ASTM A123/A123M (Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products), and relevant ANSI specifications for material properties and coating thickness. Service life is projected based on coating weight and environmental conditions, typically exceeding 20-30 years in non-aggressive environments.
8. Packaging & Shipping: Finished panels are securely packaged for transport, preventing damage.

Target industries include petrochemical, metallurgy, energy, water supply & drainage, and general construction. The non-welded, continuous structure of expanded mesh significantly enhances its strength and integrity, making it ideal for applications requiring high load distribution and security.
