Aluminum Expanded Metal Mesh
Aluminum expanded metal mesh is a type of sheet metal that has been slit and stretched to form a pattern of open spaces or "mesh." It is called "expanded" because the process of manufacturing this type of metal involves slitting the metal sheet and then stretching it, which expands the material into a larger surface area.
Aluminum Expanded Metal Mesh Characteristics
Material: Made from aluminum, which is known for its lightweight properties, corrosion resistance, and durability.
Patterns: The mesh can be formed into various patterns, including diamond, hexagonal, or square shapes, depending on the application and aesthetic preference.
Thickness: The thickness of the aluminum expanded metal mesh can vary, with different gauges available to suit different uses.
Open Area: The percentage of open space versus solid metal can be customized, which affects the weight, strength, and functionality of the mesh.
Manufacturing Process
Slitting: The aluminum sheet is the first slit along predetermined lines using precision cutting tools.
Stretching: After slitting, the sheet is pulled apart, expanding the metal into a mesh pattern. The stretching process increases the size of the sheet while maintaining the material's strength.

Aluminum Expanded Metal Mesh
Aluminum Expanded Metal Properties
Lightweight: Due to its composition and design, aluminum expanded metal mesh is significantly lighter than solid metal sheets of the same dimensions.
Strength: Despite being lightweight, it retains a high degree of strength and rigidity.
Durability: Resistant to corrosion, making it suitable for outdoor and industrial applications.
Versatility: Can be easily cut, bent, and shaped for various uses.
Applications:
Construction: Used in building facades, ceilings, partitions, and walkways, providing both aesthetic appeal and functional benefits such as sound absorption and light diffusion.
Ventilation: Ideal for vents, grilles, and filters due to its open structure, which allows air to flow freely.
Safety: Can be used in guardrails, safety barriers, and protective screens.
Decorative: Often used in interior design for decorative panels, furniture, and lighting fixtures.
Industrial: Utilized in machinery guards, shelving, and other industrial applications requiring a durable, lightweight material.
