Expanded metal is a versatile and durable material created by expanding a solid metal sheet through a process of slitting and stretching, which forms a pattern of diamond-shaped openings. This process results in a sheet that maintains strength while being lighter and offering a greater surface area than the original solid sheet. Expanded metal is widely used across various industries due to its strength, flexibility, and functional characteristics.
Name
|
Expanded Mesh
|
Material
|
Commonly made from various metals such as steel, aluminum, stainless steel, or other alloys
|
Sheet Size
|
Standard sheet sizes range from 1.22 meters (4 feet) by 2.44 meters (8 feet) or larger
|
Thickness
|
The thickness of the metal sheet can vary, ranging from 0.5 mm (20 gauge) to 3.0 mm (11 gauge) or more
|
Strand Width
|
Refers to the width of the strands between the openings; can vary based on design
|
Opening Size
|
The size of the openings or diamond-shaped holes can range from small to large
|
Strand Type
|
Standard, flattened, or raised strands, which affect the appearance and strength
|
Surface Finish
|
The surface can be plain, painted, powder-coated, or treated for corrosion resistance
|
LWD and SWD
|
Length of the diamond (LWD) and short way of the diamond (SWD) dimensions specify the dimensions of the openings

Lightweight yet Strong: The expansion process creates a material that is lighter than solid metal but retains a significant amount of strength, making it ideal for applications that require strength without added weight.
Durable and Long-lasting: The interlocking structure of the expanded metal provides excellent durability and resistance to wear, making it suitable for both indoor and outdoor applications, even in harsh conditions.
Versatile Design: Expanded metal can be customized in terms of the size and shape of the openings, as well as the thickness of the material, providing a range of options for different uses.
Open Mesh Structure: The open mesh design allows for ventilation, light transmission, and visibility, which makes expanded metal a popular choice for security fencing, protective barriers, and architectural features.
Corrosion Resistance: Many types of expanded metal are made from corrosion-resistant metals like stainless steel, aluminum, or galvanized steel, which extend their lifespan, particularly in outdoor environments.
Cost-Effective: Since expanded metal is produced through a simple process of expansion rather than cutting or welding individual parts, it can be a more affordable alternative to other types of metal mesh or sheet metal products.
In summary, expanded metal is a highly adaptable material with excellent strength-to-weight ratio, durability, and a wide range of applications, making it an essential material in industries ranging from construction to security and beyond.
