General Info About Expanded Metal Grating

Bar grating is a type of grating that consists of bars and spaces between them. If you can think about a latticework of steel bars intersecting with each other, that’s a good way to visualize bar grating.

Bar grating is an extremely versatile material used in a variety of applications, though it’s perhaps best known as the material commonly used in chain-link fencing. Bar grating comes in two forms: serrated and non-serrated.

The purpose of serrated bar grating is to prevent vertical movement in addition to preventing lateral movement. Non-serrated grating lacks the scalloped surface that serrated grating features, and it maintains a higher load-bearing capacity.

  • Kloeckner regularly stocks serrated bar grating type 19W4 in the following options:
  • 1 x ⅛ , 1 x 3/16, 1 ¼ x 3/16, 1 ½ x 3/16 Bearing Bars
  • 24” x 240” & 24 x 288” Size Ranges
  • Painted & Galvanized

Non-serrated grating has same bearing bars and size ranges, but comes in bare, painted, and galvanized options.

More Details About Expanded Metal Grating

  • Advantages/Disadvantages

    Expanded metal grating is one of the most versatile and affordable options on the market. Plus, it’s easy to work with and can be cut to fit nearly any project.

    The material is lightweight, yet strong and durable, making it ideal for projects where weight is a factor. Additionally, expanded metal grating is slip-resistant and can be finished with a variety of coatings such as hot molten zinc to resist corrosion. Expanded metal is also easy to install, which makes it a popular choice for both new construction and retrofit projects. If you are working with high temperature applications, be aware that expanded stainless steel performs better in these environments than mild steel does.

    Thanks to its strength and corrosion resistance, expanded metal grating comes with few drawbacks. The main one is that it must be welded on site, and if not manufactured properly, expanded steel can come with burrs and sharp edges.

  • Industries

    Expanded metal grating is commonly used in a variety of industries because it offers a number of specific advantages. Not only is it resistant to corrosion and impact, but it also has a high level of strength-to-weight ratio. This makes it the perfect choice for projects where weight is a factor, such as in aircraft or construction where it can support adobe or stucco walls.

    Other industries that make wide use of expanded metal include:

    • Commercial construction
    • Manufacturing
    • Water filtration
    • Audio engineering
    • Residential construction
    • Mass transportation
  • Applications

    Expanded metal grating is perfect for applications that require a strong material that won’t rust or corrode. That’s why it is in use from machine shops to construction sites.

    Additionally, expanded metal grating is slip-resistant and can be used in both indoor and outdoor applications. It’s also easy to install, making it a great choice for homeowners’ DIY projects.

  • Machining

    To create expanded metal, steel fabricators roll a single sheet through a machine that cuts to different dimensions. It’s similar to a rolling plate machine because it cold rolls and flattens the metal as it machines it. Once pressing is complete, the metal is stretched into a uniform design.

  • Welding

    Technically, expanded metal can be welded, but the process is often a frustrating one for the welder. The thin strands of metal can get burned off under the torch. One solution is to pre-heat the metal. Another is to focus your weld pull on the thicker material, which you are welding your expanded metal sheet to, and then to push onto the thinner strands.

  • Heat Treatment

    Expanded metal grating undergoes a heat treatment process that makes it ideal for a variety of applications.

Frequently Asked Questions About Expanded Metal Grating

  • What is the difference between metal grating and bar grating?

    ANSWER:

    All bar grating is metal grating, but not all metal grating is bar grating. Bar grating can be used for a number of applications, and as such is often made from a thicker material than metal grating. Kloeckner offers expanded metal sheets that range in thickness from 1/4 inch to 1/2 inch so you have more options depending on your needs. While bar grating is usually welded together, metal grating is formed from a single sheet.

     

  • How is expanded metal grating made?

    ANSWER: 

    Expanded metal grating is made by taking a sheet of metal and expanding it out into a grid. The process starts with a metal sheet that is punched full of holes. This sheet is then fed through a machine that pulls the holes out to make strips and expands them into a grid pattern. The expanded metal grating can then be cut to size and used for a variety of applications.

  • Why is expanded metal suited for metal grating?

    ANSWER:

    If you’re looking for a product that is both durable and attractive, expanded metal grating is the way to go. This type of grating is made by stretching a metal sheet and then expanding it to create a grid-like pattern. The resulting product is lightweight, yet strong enough to support heavy loads. Plus, expanded metal grating has a high resistance to corrosion and can be used in both indoor and outdoor applications.

  • What is the difference between expanded metal grating and mesh?

    ANSWER:

    Expanded metal grating is made from a single piece of metal that has been slit and stretched to create a diamond-shaped opening. This opening allows light, air, and fluids to pass through while still providing a high level of strength and durability. Mesh, on the other hand, is made by weaving together multiple pieces of wire or metal.

  • What are typical expanded metal grating sizes?

    ANSWER:

    Expanded metal grating is available in a variety of sizes to suit your needs. The most common sizes are 2’x2′, 2’x4′, 4’x4′, and 4’x8′. However, expanded metal grating can also be custom made to fit your specific project requirements.
