What Is Expanded Metal?

 
Expanded metal is a generic term that refers to products that have been formed into a plate or tube shape by rolling or other mechanical processes during the manufacturing process of a metal material.

As well as rolling, expanded metal can also be extruded, drawn, and forged in plastic working processes, and can be produced either cold or hot, depending on the temperature of production.

The use of expanded metal can be found in a wide variety of applications. In addition to sheet and gauge metal, expanded metal can also be formed into strips, bars, wires, and other shapes.
 

Uses of Expanded Metal

 
Here are the most common uses of expanded metal :

Security: Expanded metal is often used for security purposes like fences and gates because it keeps things safe.

Walkways and Steps: People use it for walkways and steps because it’s not slippery and water can drain through it.

Ventilation: In factories and big buildings, it’s used for floors so air can flow and things stay cool.

Decorations: Some folks like to use it to make things look nice on walls or ceilings.

Storage Racks: In warehouses, it helps make sturdy shelves to keep things organized.
 

Characteristics of Expanded Metal

 
Expanded metal has several distinctive characteristics that make it a popular material for various applications:

Open Design: Expanded metal is created by cutting and stretching a sheet of metal, forming a pattern of diamond-shaped openings. This open design allows for good airflow, visibility, and light transmission while maintaining strength.

Strength and Rigidity: Despite its open structure, expanded metal is strong and rigid. It can support heavy loads and is often used in applications requiring structural integrity, such as walkways and safety barriers.

Lightweight: Expanded metal is relatively lightweight compared to solid metal sheets of similar thickness. This characteristic makes it easier to handle and install, reducing overall structural weight.

Customizable: Manufacturers can produce expanded metal with various patterns, hole sizes, and materials to meet specific application requirements. This customization allows for versatility in design and functionality.

Material Variety: Expanded metal can be made from a wide range of materials, including steel, aluminum, stainless steel, copper, and more. The choice of material depends on factors like corrosion resistance, strength, and aesthetics.

Originally, Metalex occupied a former horse farm in south Libertyville, but moved into a larger facility in 1979.
 
As Metalex continued to grow, it added to the original building in 1983, expanding the total square footage to 150,000 and adding 23 lines, a full machine shop, and a secondary processing department that included shearing, stamping and plasma cutting. A manufacturer of perforated metal tubes and perforated metal tubes primarily for fluid filtration, Metalex acquired Arcor in 2005.

8. Midwest Expanded Metal Inc.
 
The expanded metal they manufacture can be either flattened or unflattened. This pattern is called standard or unflattened, because it is made from sheets of solid metal that are slit and stretched with each stroke of an upper die, forming raised diamond patterns. The pattern is determined by the gauge and type of material, as well as the diamond size. By passing unflattened material through cold reducing mill rolls, the sheets can also be flattened.
