How big of a bearing do I need for grating?
Metal should be used for all grating supports. 2” minimum bearing shall be provided for bearing bar depths of 2-1/2” or greater. Clearances shown are recommended, but may vary in accordance with dimensional tolerances Cutouts for circular obstructions are recommended to be at least 2 inches larger in diameter than the obstruction.
What are the spacings on heavy duty gratings?
Heavy Duty grating products are commonly manufactured with bearing bar spacings ranging from 15/16″ to 38/16″ (2-3/8″) on center. The bars used to secure the position of the bearing bars are commonly designated as the cross bars.
What are the dimensions of a bar grating panel?
The overall dimension of the grating panel measured perpendicular to the bearing bar span is designated as the panel width. Commonly manufactured and stocked in 24” and 36” nominal widths, grating panels can easily be supplied in a variety of widths to suit the needs of any application.
What kind of bearing bars are used for Pressure locked gratings?
The bearing bar sizes offered for pressure locked gratings are common to those in welded steel, swaged aluminum and stainless steel gratings. In that the sizes and spacings of the bearing bars are consistent with these products, the load tables are similarly interchangeable.
