What Is Expanded Metal? Expanded metal is a sheet or a plate that is cut and stretched into a mesh to make different things. Stretching results the metal into a mesh with diamond-shaped spaces; however, many other patterns can also be made out of it.

Metal including:

– Stainless steel

– Hot rolled steel

– Cold-rolled steel

– Aluminum can be expanded easily.

The pattern can then be in a straight form or be staggered by providing the most open area ill all the columns and rows. The proportion of the open area shows the amount of space for the passage of water, air, and light. Thus, it varies as per the intended application of the expanded metal.

How is an expanded metal made?

The expanded metal is stretched, making it evident that it is produced by an expanding machine that turns the solid coils and metal sheets into an expanded metal mesh. The expanding machine is connected with a knife that decides a particular pattern for the mesh. After feeding the metal through the expanding machine, it is cut and stretched using the stretching process and pressured slitting. Those slits allow the metal to be stretched to produce uniform holes. The expanding machine is operated or programmed manually to ensure a consistent pattern as the metal is fed through. The finished metal is then wound into sheets or coils.

Different thicknesses of metal can be used depending on the intended application, and different patterns can be chosen.

Types of expanded metal:

Following are the common types of expanded metal:

1. Standard expanded metal: it is an incredibly versatile and economical type of expanded metal. It comes in a wide range of opening sizes and gauge. It is used to give a raised, rigid, and slip-resistant surface. This helps in providing rigidity and extra strength while allowing maximum air circulation. 

2. Flattened expanded metal: it is produced by cold rolling expanded metal to flatten it. It is done when a smooth platform is required, and the process elongates the length of the sheet y 5 percent. 

3. Hexagonal expanded metal: this metal has hexagonal openings instead of diamond ones. Its hexagonal shapes give extra strength to the metal and allow the passage of light, air, sound, heat, and liquid. Therefore, the hexagonal openings are preferred over the diamond ones. 

4. Architectural expanded metal: this metal features the diamond pattern with the addition of architectural features. It results in a design that combines increased privacy and security, pleasing aesthetics, and improved ventilation.

5. Micro expanded metal: the openings can be hexagonal, standard, square, and flattened. This kind of expanded metal is generally used in filters.

Benefits of expanded metal:

Following are some of the benefits of using the expanded metal:

1. Cost-effective

2. Efficient process

3. Good conductor

4. Protective reinforcement

5. High strength

6. Low weight

7. Allows circulation

8. Acoustic properties

At supermarkets, there is a wide range of metals with a variety of applications. They include alloy steel, stainless steel, tool steel, galvanized steel, bronze, brass, and copper.
