Standard Expanded Metal or Regular Expanded Metal is a finished product,
which is simultaneously slit and stretched by a press to form a piece construction.
Expanded Metal provides a high strength to weight ratio, and is often used to protect
machines or people, by stopping a specific size material from entering a specific area. All Metals such as Stainless Steel Alloys, Aluminum, Titanium, Steel, & Cooper, can all be expanded for various uses including enclosures, support, protection, decoration or filtration. The charts below will help determine which product size and dimensions best suit the needs of your application.

Standard Product Range

The following is a sampling of dies that are available from Dexmet. We produce over 100,000 configurations and can design a die to suit your particular application.

LWD (Long Way of the Diamond), measured from the center of the joint to the center of the adjacent joint. This dimension is built into the tool, and is always parallel to the width of the coil and corresponds with the diamond dimension.

SWD (Short Way of the Diamond) is the length of the short axis way of the diamond, measured from the center of the joint to the center of the joint. For each fixed LWD dimension, there is a range of SWD dimensions available as shown above.

Ductile Metals: Aluminum, Brass, Cadmium, Columbium, Copper, Gold, Inconel, Lead, Magnesium, Nickel, Nickel Alloys, Phosphor Bronze, Platinum, Silver, Stainless Steel, Low Carbon Steel, Tantalum, Titanium, Zinc, Zirconium, etc.

Plastics: Nylon, Polypropylene, Polyethylene, Mylar, Teflon, Tefzel, etc.
