Expanded metal is produced in an expanding press where the basic metal is simultaneously slit and cold-formed, expanding the slits into various shapes like squares, diamonds, hexagons, and other decorative patterns. This process involves shearing a metal plate so that it stretches, creating diamond-shaped voids surrounded by interlinked bars of metal. The most common manufacturing method involves both slitting and stretching the metal in a single motion.

Specifications

Expanded metal is manufactured with specific characteristics that define its application and functionality in various industries.

• Long Way Opening (LWO)
  The LWO ranges from 4mm to 100mm. This measurement is crucial as it dictates the transparency and pattern design of the mesh, affecting how it is used in architectural and functional applications.
• Short Way Opening (SWO)
  The SWO varies between 2mm and 40mm. This dimension determines the closeness of the mesh strands, impacting both the design and the physical properties of the expanded metal.
• Strand Width
  Strand widths range from 0.5mm to 8mm. This specification is essential for determining the mesh’s strength and visual appearance, playing a significant role in its structural integrity.
• Thickness
  Material thickness in expanded metal varies from 0.3mm to 12mm. Different thicknesses cater to varying load-bearing requirements, making the metal suitable for a wide range of structural applications.
• Surface Finish
  Expanded metal can be finished with anodizing, powder coating, or galvanizing. These finishes enhance both the durability against environmental factors and the aesthetic appeal of the metal.
• Long Way of Diamond (LWD)
  The LWD ranges from 12mm to 200mm, measuring the diagonal distance between points in the diamond-shaped openings. This dimension is crucial for the overall appearance and structural strength of the mesh.
• Overall Thickness
  Including the raised strands, the overall thickness ranges from 0.5mm to 40mm. This adds a three-dimensional effect to the mesh, enhancing its visual and functional properties.
• Open Area
  The open area percentage ranges from 20% to 80%. This specifies the proportion of open space within the mesh, allowing for varying degrees of light penetration and airflow, essential for applications requiring ventilation.
• Weight
  The weight of expanded metal typically ranges from 2kg/m2 to 10kg/m2, depending on the material and its specifications. The weight is an important factor for considering its use in architectural designs and support structures.
