EXPANDED METAL

Expanded metal refers to a type of sheet metal that has been cut and stretched into a mesh-like pattern, often forming diamond or hexagonal shapes. This process creates a lightweight, durable material with unique structural and aesthetic properties.

HOW EXPANDED METAL IS MADE

Metal Sheet: A flat sheet of metal is the starting material (commonly steel, aluminum, stainless steel, or other alloys).

Slitting and Stretching: A specialized machine simultaneously cuts slits into the sheet and stretches it, creating an interconnected mesh of openings.

Finishing: The material may undergo additional processes such as flattening, galvanizing, or coating for specific applications.

Key Features of Expanded Metal

• Strength-to-Weight Ratio: The stretching process enhances the material’s strength while keeping it lightweight.
• Ventilation and Visibility: The open areas allow for airflow, light passage, and visibility, making it ideal for certain functional and aesthetic applications.
• Non-Wasteful Process: Since the sheet is stretched rather than punched out, there is no material waste.

TYPES OF EXPANDED METAL

Standard Expanded Metal:

• Has a raised, rough surface.
• Offers enhanced grip for anti-slip applications.

Flattened Expanded Metal:

• The raised surface is rolled flat.
• Provides a smoother, more polished finish.

Decorative Expanded Metal: Features unique patterns for architectural or artistic uses.

Micro-Expanded Metal: Fine mesh with small openings, often used in filtration or shielding applications.

ADVANTAGES

• Durability: Highly resistant to stress and impact.
• Customization: Available in various sizes, patterns, and materials.
• Cost-Effective: Efficient manufacturing process reduces costs.
• Versatility: Suitable for functional and aesthetic purposes.

If you’re considering using expanded metal for a project, it can be tailored to meet specific load, ventilation, or design requirements. Let me know if you’d like detailed specs or advice on material selection!
