Expanded Metal Strength

The strands and bonds of the diamond shaped trusses add strength and rigidity.

Expanded metal strength.

The weight per square foot and the shape of the diamond pattern determine the load capacity of the grating. A simple model was developed using basic solid mechanics. The main considerations when using expanded metal will be the chosen thickness and strand dimensions weight and structural design requirements. An analytical expression for the ultimate strength of expanded metal panels subjected to shear loading was developed herein.

It is available in a galvanized finish to provide corrosion resistance and additional strength. 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. Expanded metal is stronger than an equivalent weight of wire mesh such as chicken wire because the material is flattened allowing the metal to stay in one piece the other benefit to expanded metal is that the metal is never completely cut and reconnected allowing the material to retain its strength. Expanded sheet metal is available in standard raised or flattened diamond patterns in a variety of gauges opening sizes and sheet sizes.

Carbon steel expanded metal is a sheet that has been slit and stretched into a solid non raveling mesh with diamond shaped openings. Numerous gauges opening sizes and sheet sizes provide endless options that will. 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. Our expanded metal sheet is available in many sizes openings and material types.

Direct metals offers expanded metal materials such as aluminum carbon steel galvanized steel or stainless steel. Expanded metal grating is available in carbon steel and aluminum. Expanded metal has been stretched rather than punched reducing scrap metal waste. Custom sizes are available along with 2d and 3d micro mesh designs to adhere to alternative applications.
