Flattened Expanded Metal

Each sheet is expanded in the regular form and then passed through a cold rolled reducing mill. In this process the length of the sheet is elongated - usually about 5% - but the width of the sheet remains the same. The sheet is then sent through a leveler to maintain its flatness.

Typical applications of flattened expanded metal include protecting enclosures, shelving and ramps.

Standard Expanded Metal

Regular Expanded Metal is a finished product as it comes from the press after having been die cut and expanded. Each sheet that comes off the expander is in standard or regular form with the junctions at the strands and bonds forming a ridge surface.

The illustration to the right shows that the strands and bonds form a sharp angle to the original plane of the solid sheet.
