34 | BAR GRATING 800.237.3820 SWAGE-LOCKED BAR GRATING McNICHOLS ® Swage-Locked Bar Grating is manufactured using an exclusive swaging (or pinching) and forming process that prevents the bearing bars from moving. These Aluminum-only panels are available in numerous bearing bar types and heights. GAL & SGAL SERIES McNICHOLS ® GAL Series Grating is lightweight, corrosion-resistant, and available with a 1-3/16" bearing bar spacing. Our SGAL Series can handle heavier loads due to its 15/16" spacing. Both products have a serrated surface option for maximum traction. We can cut your GAL or SGAL Series Bar Grating to size and quickly assemble Stair Treads in house from stock inventory. Need your items fast? Great news ... McNICHOLS has your items in stock and ready to go!

bolded black line produce a deflection of 1/4" or less under a uniform load of 100 lbs./sq. ft., allowing for safe pedestrian comfort (also applies to SGAL Series unless otherwise indicated by a bolded green line). Values to the right are applicable to other types of loads at the discretion of a licensed engineer. For 1" height and taller serrated surface bars, subtract 1/4" from the bearing bar height and reference that loading information listed in the table. For example, a 1-1/2" height with a 3/16" thick serrated bearing bar has the same loading values as a 1-1/4" height with a 3/16" thick smooth (non-serrated) bearing bar. Loading and deflection values are based on a maximum allowable fiber stress of 12,000 PSI, E = 10,000,000 PSI. Technical information provided is theoretical and for evaluation by technically skilled persons only, with any use thereof to be at their independent discretion and risk.
