Types of Expanded Metal

Expanded metal is a versatile industrial material produced by slitting and stretching sheet metal into an open metal mesh grate. This manufacturing process creates a strong, lightweight product with excellent load distribution, airflow and visibility, without generating scrap.

At Argus Steel, we supply multiple expanded metal types to meet your industrial application requirements, ranging from safety and access to screening and structural support. Understanding the different types of expanded metal helps ensure you choose the right material for performance, durability and compliance.

Standard Expanded Metal

Standard expanded metal, often called raised expanded metal, is produced directly from the expanding process and left in its original three-dimensional form. The strands and bonds remain raised, creating a rigid surface with added depth and strength.

This type of expanded metal is commonly used when you need slip resistance, strength, and ventilation. The raised surface provides natural traction, making it suitable for industrial environments where you require safety and grip.

Typical industrial applications include:

  • Machine guards and safety barriers.
  • Protective screens and enclosures.
  • Industrial partitions.
  • Ventilation panels.
  • Equipment shielding.

Flattened Expanded Metal

Flattened expanded metal is produced by running standard expanded metal through a rolling mill, flattening the raised strands into a smooth, uniform surface. This process improves handling, increases dimensional consistency and creates a flatter profile.

Flattened expanded metal is the top choice when you need tighter tolerances or smoother surfaces, such as in applications involving contact with equipment, components or personnel.

Typical uses include:

  • Walkway infill panels.
  • Guarding and screening.
  • Shelving and storage systems.
  • Filtration and separation applications.
  • Support panels and backing.

Compared to raised expanded metal, flattened expanded metal offers easier stacking, improved fit-up and a more consistent thickness across the sheet. It maintains strength while providing a cleaner, lower-profile solution for industrial installations.

Expanded Metal Grating

Expanded metal grating, sometimes referred to as catwalk mesh or project mesh, is designed for applications that require load-bearing capability combined with drainage, airflow and visibility. This expanded metal type is manufactured using heavier gauges and specific patterns to support foot traffic and equipment loads.

Expanded metal grating is commonly used in industrial access systems where safety, durability and reduced material weight are priorities. This includes:

  • Catwalks and platforms.
  • Industrial stairs and ramps.
  • Mezzanine decking.
  • Maintenance access areas.
  • Equipment platforms.

Compared to a solid plate, expanded metal grating provides excellent slip resistance while allowing debris, water and other materials to pass through. This helps reduce buildup and maintenance in demanding industrial environments.

Selecting the Right Expanded Metal Type

Choosing the correct expanded metal type depends on several factors, including:

  • Load and strength requirements.
  • Safety and slip resistance needs.
  • Open area and airflow requirements.
  • Installation method and tolerances.
  • Material and environmental exposure.
