Types of Grating

Industrial operations rely on different grating styles to handle traffic demands, airflow requirements or liquid drainage. Argus Steel distributes the full spectrum of options:

  • Welded bar grating: A durable, all-purpose choice built from welded load bars and cross bars. Available in carbon, galvanized steel bar grating or stainless steel grating.
  • Pressure-locked grating: Ideal when uniform appearance and controlled spacing matter. Offers tight dimensional accuracy and supports a wide range of series, including close-mesh spacing.
  • Swage-locked grating: A common option for aluminum systems. Provides a lightweight solution for walkways and platforms where reducing overall weight is a priority.
  • Riveted grating: Known for high strength and vibration resistance. Provides a stable walking surface in demanding industrial settings.
  • I-bar aluminum grating: Features an I-shaped bearing bar to maximize strength-to-weight ratio. Often chosen for structures that need long spans with minimal added mass.
  • Extruded plank grating: Plank sections formed with integrated traction surfaces. Used frequently in catwalks and plant walkways where slip resistance is essential.
  • FRP grating (pultruded or molded): Nonconductive, corrosion-resistant material used in environments where metal is not ideal.

Spacing, ADA and Surface Options

Bar grating sizing varies based on traffic type, load requirements and open area. Industry series such as 19-W-4, 15-W-4 and close-mesh patterns determine bar spacing and overall layout. Close-mesh patterns help reduce opening orientation for applications requiring increased heel resistance or ADA considerations.

Surface options include smooth tops for general use or serrated tops for environments requiring added grip. Serrated surfaces can assist with traction where moisture, oils or outdoor exposure are persistent factors.

Materials and Finishes

Argus Steel distributes bar grating in multiple materials to suit diverse operating conditions:

  • Steel in mill finish, galvanized, painted or powder-coated
  • Stainless steel grating for corrosive or sanitary environments
  • Aluminum for lightweight platforms or long-span walkways
  • FRP options for chemical processing or non-metallic structures

Each material supports different mechanical and environmental performance expectations, allowing you to match the product to your facility’s long-term operational needs.

Stair Treads

Industrial stair treads are available in various depths and widths with smooth or serrated surfaces. Options include abrasive or metal nosing, pre-drilled ends and configurations compatible with standard bar grating dimensions. These treads help maintain consistent walkability in plants, warehouses and access structures.
