How Expanded Metal Is Made?

Aug. 06, 2022

Metal grating is a metal product produced by perforating metal sheets or joining metal strips to form a grid. They are metal product that is widely used in various industries such as stairs, platforms, scaffolding, and guards. The different processes used to produce metal gratings include expansion, perforation, forming, and welding.


Almost any metal can be used to make metal gratings. The most common types are iron, carbon steel, aluminum, and stainless steel. Metal grating is commonly used as a non-slip safety surface for applications that require a safe work platform.


Types of Metal Grating

Metal grating panels vary greatly in material and function. Depending on the application, different types of metals and production patterns are used to ensure successful and safe operating conditions. These factors depend on parameters such as strength, size, location, and use.

How expanded metal is made?

Expanded metal grating panels are made by creating slits in the metal sheet and then stretching (expanding) the sheet to form a diamond pattern. The sheet can then be cut to a certain size and flattened. Many different types of metals can be expanded, such as stainless steel, carbon steel, aluminum, etc.


The expansion process is very economical because it produces no waste and because no holes are punched in the material, the sheet will retain its structural strength. Typical uses for expanded metal grating include steps, flooring, fencing, and security applications.


Bar Grating Panels

 Bar Grating  


Bar grating panels are made by connecting parallel bars to vertical bars. The most common method of joining bars is welding, however, there are other ways to join bars. Alternative methods include riveting, close engagement, compression locking, etc. The most economical method of joining is determined by the material used and the thickness of the bar.


Fences can be made of a variety of different materials, but are most commonly made of steel or aluminum. It has a very high strength-to-weight ratio and a large amount of open space, making it a widely used choice for industrial flooring. However, it is also used for such things as fire escapes, street drains, and bridges.


Safety Grating Panels

Safety grating is a common form of metal grating used for walking surfaces. It is designed to help increase traction and prevent the risk of slipping or falling. It is usually made of small diamond-shaped protrusions that allow for greater traction. It also has many open surfaces that provide plenty of drainages and airflow. The most common form of safety fence helps increase grip when walking over it. This is achieved by serrating the diamond edges that are created after cold stamping the sheet metal.


Many different types of metals are used to make grip stanchions, including steel and aluminum. Once it has been stamped and serrated, the sheet metal is coated with a material that minimizes slippage. Because of its high level of traction, it is used in applications such as sidewalks, stairs, and other walking platforms.
