Expanded metal


Expanded metal sheet with diamond holes is the most frequently used expanded material used in different areas of industry, architectural projects as well privately. Besides the biggest range of mesh sizes, expanded metal sheet with diamond holes is the most available stock material. Thanks to the simple classical design of its grid it is airy, safe and provides good light transmittance, its use is versatile. This type of expanded metal sheet is popular for its variability (reversing the mesh) and manufacturing flexibility. Thanks to our long-standing experience from the fabrication of diamond meshes, we can react readily to any of your specific requirements.

Expanded metal is made according to DIN 791 standard.
