McNICHOLS® Bar Grating - Press-Locked
McNICHOLS® Bar Grating brings safety, strength, durability and character when installed in either industrial or architectural applications. It regularly appears on catwalks, factory floors, platforms, railing infill panels and as Stair Treads. A series of bearing bars are welded, swage-locked or press-locked together with perpendicular crossbars to form the panels. Bar Grating is a rugged, high-performance, low-maintenance and slip-resistant product capable of handling pedestrian or vehicular loads. Common material types include Aluminum, Carbon Steel, Painted Carbon Steel, Galvanized Steel and Stainless Steel. We also supply a hexagonally clinched product referred to as HEXMESH™ which is commonly used as a liner in concrete structural shapes to help prevent cracking. If your application requires ADA compliant Grating, CLOSE MESH (close space Grating) options are available in welded and press-locked construction types. Swage-Locked Aluminum SAFE-T-GRID® TB-940 Bar Grating is also a great ADA compliant choice. McNICHOLS has the nation’s largest selection of Bar Grating and is certain to have what you need for your application.

Consider Bar Grating uses and physical requirements for your interior or exterior application. Loading, span and support needs as well as traffic requirements such as pedestrian, hand cart and vehicular are important considerations. Several Bar Grating products comply with the Americans with Disabilities Act (ADA) when installed to written standards. We invite you to browse Bar Grating applications in our Product and Application Gallery.
Choose from Welded, Heavy-Duty Welded, Swage-Locked, Press-Locked or Clinched construction types.
Series Type & Name
Determine the series type and name (GW-100, GHB-150, GAL-125, etc.) of the Bar Grating product for your project. If applicable, items that comply with the Americans with Disabilities Act (ADA) standard will have this language indicated in the product's description and item specifications of the applicable product.
Select the product spacing (the measurement from the center of one bearing bar to the center of an adjacent bearing bar) of the Bar Grating item. Product Spacing (e.g. 19-W-4) refers to the industry specification for Bar Grating products. For example, the first number refers to the bearing bar spacing measured on center (19 = 19/16" or 1-3/16"), the letter refers to the construction type (W = welded), and the last number references the cross bar spacing measured on center (4 = 4").
Primary Material / Product Finish
Select the primary material type including Aluminum, Carbon Steel, Carbon Steel - Painted Black, Galvanized Steel or Stainless Steel. Inventory is typically "mill finish" for Aluminum, Carbon Steel and Stainless Steel. Hot-Dipped Galvanized, Painted Black or Painted Gray finishes are available for some Carbon Steel items. We provide more information on Primary Material Types and Product Finishes in the links provided in the Overview section on the Bar Grating Resources landing page.
Bar Size & Shape
Choose the bearing bar height and thickness (e.g. 1-1/4" Height x 3/16" Thick) and the shape (Rectangular Bar, I-Bar or T-Bar).
Determine if your application requires a smooth, serrated or grooved product surface.
Percent Open Area
Choose the percentage of open area desired in the panel or pieces of Bar Grating.
Choose the direction the bearing bars need to run to support the application load. Bearing bar direction is often referred to as span. Clear Span refers to the distance between Bar Grating supports. Bearing bar direction is an important installation consideration.
Product Size, Form & Quantity
Identify the number of panels (width and length) and/or sizes (cut-to-size pieces, areas, stair treads) and cut types (random, uniform, equal stub). Areas exceeding standard panel widths are provided in multiple pieces to width.
Specify any requirements such as fabrication, banding, notching, cut-outs, toeboards, Stair Treads, non-standard tolerances, etc.
Determine if Bar Grating Accessories like Clips or Fasteners/Hardware, Carrier Plates, etc. are needed for your project or application.
