Expanded Metal Grating

Expanded metal grating is the ideal material for industrial walkways. Expanded metal mesh grating combines light weight with unusual strength because each diamond is designed like a truss: every strand works to distribute the load in all directions to the supporting structure. Although Expanded Metal Grating is used extensively for walkways, it also has many other uses.

Expanded metal mesh grating is identified by weight per square foot. Carbon steel expanded metal grating is available from stock in 3, 3.14, 4, 4.27, 5, 6.25 and 7 pounds per square foot. Aluminum expanded metal mesh grating is available from stock in 2 pounds per square foot and stainless steel expanded metal mesh grating is available from stock in 3.3 and 4.5 pounds per square foot.

Expanded Metal Projection Mesh Grating

We feature another expanded metal grating called projection mesh. Projection mesh expanded metal safety grating features small tooth-like projections on the upper surface of the mesh. These projections provide an excellent non-slip surface where additional anti-skid surfacing is desired. Projection mesh expanded metal grating is available in carbon steel in 2 and 3 pounds per square foot and in aluminum in 1 pound per square foot.

Expanded Metal Stair Tread/Catwalk Grating

Stair treads and Catwalks are heavy duty types of expanded metal made from carbon steel, aluminum, stainless steel and other alloys. They are safety oriented, lightweight and open in design which makes them ideal for use in a multitude of commerical and industrial applications. In addition to the regular grating products, we also manufacture Projection Mesh Safety Grating.

Projection mesh, available in either carbon steel or aluminum, is a distinctively designed expanded metal safety grating product. Projection mesh has tooth-like projections on the the upper surface of the design, which provides an excellent non-slip surface where a safer walking and working surface is needed.

Expanded Metal Grating Features & Benefits

A heavy duty expanded metal mesh produced from steel plate and contains no welds or joints; each sheet is a single piece of steel and has a large open area.

Expanded Metal Gratings Strengths

Meets the deflection requirements of Federal Specification RR-G-661b on clear spans up to 40 inches and less than 100 pounds per square foot uniform load. Grating tests confirm that larger spans and greater loads may be accommodated if the amount of deflection is not critical.

Expanded Metal Gratings Low Cost

It is generally more economical to build walkways and platforms with expanded metal mesh grating than with other types of steel grating. With savings of up to 50%, the reduction in dead weight afforded by the use of expanded metal grating is also a plus factor in the design of large structures.

Expanded Metal Gratings Safety

Metal gratings provide a natural slip resistant walking surface. The high percentage of open area, a characteristic of expanded metal mesh grating, allows snow, water and oil to drain off easily, thus maintaining the slip resistant surface. Metal gratings also allow excellent passage of heat and light and contribute to walkway cleanliness.

Expanded Metal Gratings Handling & Job Fabrication

Our metal mesh gratings come in convenient sheet sizes and are lightweight. Job fabrication and fitting is easy and can be done with one or two men with simple cutting and welding equipment. Our grating sizes make it possible for installation on walkways and platforms even though the structure has been completed.

Uses for Expanded Metal Gratings

  • Catwalks
  • Platforms
  • Billboards
  • Conveyor Walkways
  • Drain Covers
  • Stair treads
  • Mezzanine Floors
  • Scaffolding
  • Maintenance Platforms
  • Partitions
  • Ramps
  • Mooring Docks
  • Fencing
  • Truck Body and Bulkheads
  • Vaults


Grating: Grating is a standard expanded metal pattern produced from heavier gauge low carbon steel plates. The strands and openings are considerably larger than the other meshes.  Ideal for use whenever a strong, durable and lightweight surface is required.  Although used primarily for pedestrian traffic, grating can accommodate heavier loads when properly supported.
