Bar Grating

1

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.

2

Construction Type

Choose from Welded, Heavy-Duty Welded, Swage-Locked, Press-Locked, or Clinched construction types.

3

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.

4

Product Spacing

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").

5

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.

6

6

Surface Profile

Choose the surface profile for your application. A surface profile includes the number of openings to width, type of opening, and the width of the Plank or Walkway measured in inches (e.g. 5-Diamond (11-3/4" Width), 6-Hole (12" Width), etc.).

7

Channel Size

Select the channel depth or height for your surface profile selection. The channel size for Plank products is referred to as depth. For Walkway products, the channel size is referred to as height because of its upturned profile above the surface of the product. When specifying GRATE-LOCK® Interlocking Plank Grating, it is important to identify channel flange requirements (e.g. Male Channel Flanges, One Female and One Male Channel Flange, Female Channel Flanges).

8

Percent Open Area
