Our dedicated, purpose-built expanded metal machines simultaneously slit and stretch longitudinally.
The sheet advances between the top and bottom tool as the top tool indexes left and right. This expands the sheet to reveal diamond shaped holes.
No metal is removed in this process. The final product is just longer, stronger and lighter than the original sheet without the costs of waste disposal. The output of this process can then be blanked to the required shape and then formed.
