Expanded Metal Strength

An analytical expression for the ultimate strength of expanded metal panels subjected to shear loading was developed herein.

Expanded metal strength.

Expanded metal has been stretched rather than punched reducing scrap metal waste. Expanded sheet metal is available in standard raised or flattened diamond patterns in a variety of gauges opening sizes and sheet sizes. Expanded metal grating allows snow water and oil to drain off easily making a practical yet economical way to assure strength and safety in a walking surface. The weight per square foot and the shape of the diamond pattern determine the load capacity of the grating.

The main considerations when using expanded metal will be the chosen thickness and strand dimensions weight and structural design requirements. Our expanded metal sheet is available in many sizes openings and material types. The strands and bonds of the diamond shaped trusses add strength and rigidity. Direct metals is an expanded metal supplier of versatile and economical expanded metal that is made from a high quality metal sheet.

Custom sizes are available along with 2d and 3d micro mesh designs to adhere to alternative applications. A simple model was developed using basic solid mechanics. Carbon steel expanded metal is a sheet that has been slit and stretched into a solid non raveling mesh with diamond shaped openings. Direct metals offers expanded metal materials such as aluminum carbon steel galvanized steel or stainless steel.

Numerous gauges opening sizes and sheet sizes provide endless options that will. Expanded metal grating is available in carbon steel and aluminum. It is available in a galvanized finish to provide corrosion resistance and additional strength. Expanded metal is supplied in a standard raised diamond pattern or a flattened variety and materials include aluminum carbon steel galvanized steel and stainless steel.
