Information on the Different Types of Metal Gratings

Apr. 15, 2022

Using a variety of different materials, classifications and applications, it can be difficult to determine which type of metal grating you should use for your project. To help, we have provided detailed information about the different types of metal gratings, including how they are manufactured, their properties and common applications. 

What are metal gratings?

In the metals industry, the term "grating" can refer to several different types of metal products. Each type has its own set of unique properties that make it more (or less) desirable for individual applications. For example, street drains will use one form of grating, while sidewalks often require a more secure form of extended grating or clamp bar. Regardless of its individual application, metal grating as a whole allows for proper drainage, ventilation and safety measures in a variety of industries.

Do you need metal grating for your project? ZERUN has the products you need.

Steel Grating

Expanded metal grating is made by creating slits in a metal sheet and then stretching (expanding) the sheet to create a diamond pattern. The sheets can then be cut to 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 creates no waste and because no holes are punched out of the material, the sheet will retain its structural strength. Typical uses for expanded metal grating include steps, flooring, fencing and security applications.

Bar Grating

Bar gratings consist of parallel and perpendicular bars joined together. The bars are most commonly joined by welding, however, there are other methods of joining bars together. Alternatives include riveting, tight engagement, compression locking, etc. The most economical method of connection depends on the material used and the thickness of the reinforcement.

Bar grating can be made of many different materials, but is 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.

Safety Grating

Safety grating is a common form of metal grating used on walking surfaces. It is designed to help increase traction and prevent the risk of slips or falls. It is usually made of small diamond-shaped protrusions that provide greater traction. It also has many open surfaces that provide ample drainage and air flow. The most common form of safety grating helps increase grip when crossing it. This is achieved by forming serrations on the diamond edges formed by cold stamping the sheet metal.

Woven Wire Mesh

Wire mesh, which can also be referred to as wire fabric or cloth, is a form of metal grating consisting of parallel rows and crossed columns of wire. It is easy to install, very durable, and can be used in a variety of different industries. Because it can be made of a variety of different materials and metals and can meet an almost unlimited number of specifications, it is very versatile and can be used for many different applications.

The two most common types of wire mesh are: welded wire mesh or woven wire mesh.

Perforated Metal

Perforated metal, also known as perforated sheet, perforated plate or perforated screen, is a form of metal grating made from stamped or punched metal sheets to produce a specified pattern of holes. It is typically made of stainless steel, carbon steel or aluminum and is made by several different metal manufacturing processes. These include rotary pin perforation, punching and perforation, and laser perforation. 

During the perforation process, the removed metal is recycled, improving sustainability and reducing overall metal usage. This material reduction typically translates into weight savings and reduced transportation costs.
