What is Standard Expanded Metal?

Standard Expanded Metal is a metal sheet that has undergone a process of slitting and stretching to create a mesh with diamond-shaped openings. Known for its strength, versatility, and lightweight properties, it is often referred to as “raised expanded metal” due to its elevated strands and bonds that form a textured surface.

Key Features of Standard Expanded Metal

1. Strength and Durability
   • Manufactured from solid sheets, this material maintains its integrity without joints or welds, ensuring high structural strength.
   • Suitable for heavy-duty applications.
2. Lightweight
   • The process of expansion reduces the overall weight of the material while maintaining its strength.
3. Versatility
   • Available in various materials like stainless steel, carbon steel, aluminum, and copper, making it adaptable for diverse applications.
4. Excellent Ventilation
   • The open design allows free flow of air, light, and heat, making it ideal for ventilation and safety applications.
5. Cost-Effective
   • The expanding process creates more material surface area from a single sheet, optimizing cost efficiency.
6. Anti-Slip Surface

Standard Expanded Metal Sizes

Expanded metal sizes include measurements for three main dimensions:

1. SWM (Short Way of Mesh): The spacing between the center points of two adjacent short diamond-shaped openings.
2. LWM (Long Way of Mesh): The distance between the centers of two long diamond-shaped openings.
3. Strand Width: The width of the solid metal left between openings, contributing to the material’s strength.
