Table of Spacings Available
The following table illustrates bearing bar and cross bar spacings common to grating products. Bearing bar spacings range from 1-3/16" on center to 7/16" on center. Cross bars are typically spaced at 4 inches on center, and 2 inch centers are available for traffic areas where small-wheeled carts or dolleys are anticipated.
How To Specify
Proper specification of Algrip Slip Resistant Gratings requires identification of the following components:
METHODS OF ASSEMBLY - select type "W", "PS" or "PD"
MATERIAL - specify the desired material - A-1011 Carbon Steel, type 304 or 316 Stainless Steel, type 6063 or 6061 aluminum.
BAR SPACING - select the desired spacing from the "Table of Spacings Available" above.
BEARING BAR SIZE - select the appropriate bearing bar size for the desired span and load from the load tables in this section of the website.
FINISH - specify desired finish. Common finishes are as follows:
CARBON STEEL - bare, prime painted or hot dip
galvanized after fabrication.
STAINLESS STEEL - mill finish or abrasive blast
matte finish
