Bar Grating

Our industrial metal gratings are available as stock panels or are custom fabricated to your size and specifications. This includes options available in stair treads. Stair treads can be custom fabricated to your needs with both smooth or serrated surfaces, and a variety of non-slip nosing options.

Offered as bar gratings, & plank gratings/planks, we have a choice of standard spacing for normal pedestrian traffic or close mesh for high heels or ADA compliance.

Material options include plain steel, galvanized steel, aluminum, or stainless steel. Our fiberglass reinforced plastic (FRP) industrial grating options are pultruded, I-bar, or molded.

We have many types of gratings available:

  • Welded Steel and Pressure-Locked: Permanent locking solutions that can withstand extreme pressure. Cross bars remain in a fixed position for a uniform appearance. Our products are ideal for industrial or architectural installations as light and air are allowed to pass through.
  • Swage-Locked: A type of grating useful for industrial applications involving liquids. Swage-locked grating consists of cross bars lined through preexisting holes in a metal material. Aluminum swage-locked grating is a popular choice for industrial walkways and platforms.
  • Riveted: An industrial form of grating featuring a series of crimp bars. Riveted grating products allow users to create durable joints when fastening metal surfaces together.
  • Reticuline: Industrial grating products with rounded metal connections. Reticuline grating is excellent for stair treads and platforms where slipping is a concern.
  • I-Bar: A lightweight metal grating configuration that offers exceptional strength. Straight weight-bearing bars leave room to draw up walkways, platforms, and stairs based on the dimensions of your facility.
  • Extruded Plank: Industrial grating products with intricate vents. Extruded plank grating is perfect for catwalks and industrial walkways, as designs are engineered for maximum traction. Allow air, light, and heat to pass through metal without compromising safety initiatives in your plant or facility.
  • X-Bar Press-Locked: Metal products that have cross bars connecting at a slight angle. Here, manufacturing procedures result in surfaces that have “X” shape designs throughout.

Bar grating thicknesses measure .75″ to 6″ high. Finishes offered are mill finish, painted, powder coated, or galvanized with either smooth top or a serrated top. Grating can have either untrimmed ends (open fingers), or trim banded (closed ends).

Grating can be provided to comply with the Americans with Disabilities Act if requested. All of our gratings are load tested to ensure strength and safety. On large fabricated jobs, we will prepare drawings for your approval and erection.

Most Common Types of Grating

Welded Steel Grating

Welded Steel Grating is made by welding steel cross bars to steel load bars. An economical product, welded steel gratings are suitable for walkways, platforms, metal catwalks, stair treads, mezzanine decking, security screens and general industrial and commercial purposes. Welded grating is produced in carbon, galvanized, and stainless steel alloys.

Pressure Locked Grating

Pressure locked grating is among the most versatile types of metal grating because as it offers a wide variety of bar spacings. Pressure locked grating is the grating of choice for architectural applications, including close mesh grating for ADA applications, for high traffic public pedestrian areas, decorative facades and ornamental grilles. Argus Steel offers pressure locked grating in a full-range of materials: carbon steel, galvanized steel, aluminum, and stainless steel.

Swage Locked Grating

Swage locked grating is the most common type of aluminum bar grating. Assembled by punching a square cross bard through the aluminum bearing bars, ultimately locking the grating into place through a swaging process. Ideal for walkways in areas where material weight is a concern, aluminum grating offs a more light weight alternative to steel and stainless steel grating.
