Applications
Expanded metal mesh is widely used in building facades, decorative panels, walkways, staircases, walkways and platforms, ventilation screens, sunshades, and safety covers. Below is a quick guide on which expanded mesh types are most suitable for each application:
Fine Expanded Mesh: Lightweight with a smaller opening, ideal for aesthetic applications where airflow and privacy are needed. Best for: decorative panels, feature walls, ventilation grilles, shading screens.
Medium Expanded Mesh: Balance of strength and openness, making it the most versatile option. Best for: facades, drain covers, sunscreens.
Walkway Mesh (Heavy-Duty Expanded Mesh): Manufactured from thicker material for durability and load resistance. Designed to withstand heavy foot traffic while providing slip resistance and strength. Best for: walkways, stair treads, mechanical platforms, air-con ledges, rooftop access areas, and bridges.
Louver Mesh: Designed to control visibility, sunlight, and airflow. Best for: decorative panels, feature walls, shading screens, rainscreens.

Expanded Metals FAQ
-
Expanded metal, also called expanded mesh or sheet, is a versatile material created by slitting a sheet of metal in a specific pattern and then stretching it to open up the slits. This process creates a diamond-shaped mesh that offers a number of advantages over solid sheet metal.
-
Expanded metal offers a number of benefits, including:
Increased airflow and ventilation: The open mesh of expanded metal allows air to pass through easily, making it a good choice for applications that require ventilation, such as HVAC systems and machine enclosures.
Improved sound absorption: Expanded metal can help to absorb sound, making it a good choice for applications where noise control is important.
Load-bearing strength: Expanded metal retains its strength even after cutting because it is formed from a single sheet with no welds. This makes it suitable for walkways, stair treads, platforms, and other loading applications.
-
Expanded metals are used in a wide variety of applications, including:
- Architectural applications: Exterior facades, rain screens, sunscreens
- Interior design: Partitions, ceiling panels, signage
- Walkways and Bridges: Stair treads, Platform decking
- Safety and security: machine guards, safety grates, enclosures
- Noise control: sound absorption panels
- Ventilation: air vents, grilles
-
When selecting expanded metal, consider the application, as this determines the required mesh type, strength, and opening size. Key factors include:
Material
Thickness & Strand Width
Mesh Opening
Finishing: Powder coating or galvanising for corrosion resistance and aesthetic requirements
Our team can review your drawings or site requirements and recommend the most suitable expanded metal model for your project.
