A vast selection of varying sizes and weights of expanded sheets are kept in stock at McKinsey Steel and can be sheared and bent to your needs. Hard to find extruded profiles can also be sourced for our clients.

Expanded metal comes in diamond shaped patterns. It is available in "Standard" or what can be called "Raised Expanded Metal" in which case it has a rough feeling to it, or "Flattened Expanded Metal" which means it has a Flattened Metal surface.

The "Raised Expanded Metal" type is commonly used where light vehicles are being loaded on ramps and other purposes. The "Flattened" type is often used as hand and finger guards as well as for security screens.

The first number in the description below roughly designates the narrow opening size of the diamond.
