Expanded Metal
Monday, December 31, 2018

Expanded metal has been seen by many people throughout their lives, but they aren’t aware of all the benefits it provides in several different construction and building applications. In this post, we’ll discuss how expanded metal is made, where it is used and the benefits it provides.

How Expanded Metal Is Made?

When a person first sees expanded metal, they may think that a machine was used to poke holes in a large sheet of metal to give it mesh look. While the expanded metal does start out as a sheet of metal, there isn’t any process for poking holes in the sheet.
First, a small metal sheet is inserted into an expanding machine. Inside that machine, there exists a knife pattern for cutting into the sheet. Several different patterns are available, generally in square or diamond shapes. Custom knife patterns can also be used if something different is required.

The knife first cuts into the metal sheet. Then, the machine stretches the sheet to create a diamond-mesh pattern. Consistency is ensured by the machine so that the manufacturer gets uniform cuts throughout the sheet. Stretching and sheeting a small sheet of metal into an expanded large metal sheet saves steel while leaving little waste. This makes it a wallet-friendly and environmentally conscious process.

Benefits of Expanded Metal

Expanded metal is used in many different applications and provides several advantages. Some of the benefits of expanded metal include:
  • Expanded metal lets light, fluid and air flow through easily, which enables protection of a specific area from all kinds of intrusion without entirely closing it.
  • Expanded metal is available in different varieties to meet specific needs an individual may have, whether it is grating on air conditioner or an extremely durable metal for walkways
  • Expanded metal is durable
  • A single sheet is used for creating expanded metal which is why the final product is seamless.
  • There are several different options for getting the expanded metal cut to the shape and size required.
Common Applications of Expanded Metal

Expanded metal is most commonly used in:
  • Battery cells
  • Fluid or air filters
  • Ventilation systems
  • Radar and satellite antennas
  • Speaker covering
  • Outdoor grills
  • Securing fences, walls, floors and ceilings
  • Covering appliances like an air conditioner
  • Reinforcing concrete
  • Benches
  • Walkways and stairs
Expanded metal is a great material and there are many uses for it; from small home projects to large building construction. If you want expanded metal products, visit Action Stainless & Alloys.
