Floor Forge End Plate Serrated Galvanized Steel Grating Welding Carbon Walkway

Floor forge end plate welding carbon walkway steel grating Jakarta


Metal bar grating can be defined as a series of metal bars positioned vertically, placed an equal distance apart and joined by cross members to form a rectangular or reticuline pattern. Typically manufactured from mild carbon steel, 6000 series aluminum and 300 series stainless steels, bar gratings are also available in specialty metal alloys to suit nearly any application.

The vertically positioned bars are designated as the bearing bars. These bars range in size from 3/4" x 1/8" for light pedestrian traffic to 7" x 1/2" for extreme vehicular loads. Typically, the spacing of the bearing bars is indicated in sixteenths of an inch, measured from the center of one bar to the center of the adjacent bar. This center to center or on center spacing ranges from 7/16" to 19/16" (1-3/16") on standard grating products. Standard gratings are also available with wider spacings providing an even greater open area, but should not be specified without consulting the manufacturer. 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. Crossbar profiles vary according to the method of assembly and material selected. As with bearing bars, cross bar spacing is measured as on center spacing. The customary cross bar spacing is 4" on center. On special order, 2" on center and other special spacings are also available.

Proper specification of bar gratings includes a determination of load conditions, effective unsupported clear span, flooring surface, trim and finish. Appropriate consideration of these elements plus any features unique to their particular application will allow the specifying authority to select products that will provide years of continuous service.

SPAN – In grating nomenclature, span serves a dual role in defining two significant features. First, unsupported span indicates the clear distance between effective points of support for the grating. Once the specifier has established the design load and acceptable deflection criteria, grating selection will be dictated by determining the maximum unsupported span and consulting the load tables on the pages that follow. Secondly, span indicates the overall finished length of the grating panels (parallel to the bearing bars) as they are supplied to the customer.

WIDTH – 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. For non-stock widths, consult the Panel Width Chart on page 17 of this catalog. Additionally, custom widths can be shop fabricated to hold any specific tolerance.

SERRATED SURFACE– The excellent drainage and self-cleaning characteristics of plain surface grating make it suitable for the majority of applications. In the presence of materials which could cause the top surface of the bars to become slippery, the optional serrated surface should be considered. When serrated surfaces are specified, the bearing bar depth must be increased 1/4" greater than the sizes shown in the load tables and selection guides to provide the equivalent strength of non-serrated bars.
