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 exhibits a high weight to strength ratio, and is often used to protect people or machines by stopping a specific size material from entering a specific area. All Metals such as Stainless Steel Alloys, Aluminum, Steel, Titanium, & Copper, 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.
