Metal bar gratings are widely accepted as the preferred option for open metal floors. To enhance the performance of these products, metal bar gratings can now be specified with the added safety of the Algrip Slip-Resistant surface.

Prior to assembly of the grating, the custom alloy laser deposits are applied to the walking surface of the grating bearing bars. This process produces a bar grating with superior, long-term slip­ resistance when compared to plain or serrated surface options. As with plate products, gratings are available in carbon steel, aluminum and stainless steel.

Gratings are available in bar sizes and spacings to meet the varying needs of industrial and commercial applications. Industrial applications are routinely served with Standard Mesh Grating. These products have bearing bars spaced at 1-3/16" on center and cross bars spaced at 4" on center (type 19-4).

ADA compliant gratings must have bearing bars spaced no further than 1/2" apart. To meet this criteria, gratings with 3/16" thick bearing bars spaced at 11/16" on center should be specified (types 11-4 or 11-2). To provide additional safety in areas where high-heeled shoe traffic is anticipated, type 7-4 or 7-2 spacings should be considered. These close-mesh products are manufactured with 3/16" thick bearing bars spaced at 7/16" on center and yield a 1/4" clear opening between the bearing bars.

Methods of Assembly

Algrip Slip Resistant Metal Bar Gratings are available in three distinct types of grating identified by their method of assembly. All of these gratings provide superior slip resistance when subjected to the most demanding applications.

Type "W" Welded Steel Grating Manufactured by welding the cross bar/bearing bar intersection, typically by automated forge welding machines. Provides a secure welded connection that is ideal for most industrial applications. Available in carbon steel or stainless steel.	Type "PS" Swaged Pressure Locked Grating Cross bars are inserted into pre-punched holes in the bearing bars and hydraulically swaged to lock the bars in place. Swaging is the preferred method of assembly for the manufacture of close mesh carbon steel, stainless steel and aluminum gratings.	Type "PD" Dovetail Pressure Locked Grating Assembled by inserting pre-punched bearing and cross bars into an "egg-crate" configuration and deforming the cross bars under intense hydraulic pressure. Allows for the manufacture of gratings with custom spacings.
