Product Specifications/Nomenclature

Bearing Bar (Load Bearing Bar – BB)

Manufactured using high-quality low carbon steel (IS 2062 or equivalent), ensuring strength, durability, and structural integrity. These bars support the primary load applied on the grating.

Cross Bar (CB)

Positioned perpendicular to the bearing bars and welded at intersections to provide lateral stability. Typically manufactured from square twisted steel (SAE 1008 or equivalent).

Mesh

The center-to-center spacing between bearing bars and cross bars, which determines load capacity and structural configuration.

Edge Binding / Frame Bar (FB)

Bars fixed along the edges of the grating panel to enhance strength, stability, and overall finish.

Dimensional Details

Span (S) Distance between support points, measured parallel to bearing bars
Width (W): Overall width of the panel, measured perpendicular to bearing bars
Cut-Outs: Custom openings provided to accommodate pipes, structures, or equipment

Standard Specifications are as follows

Bearing Bar Sizes 25×3, 25×5, 30×3, 30×5, 32×5, 40×5, 50×5, 60×5, 70×5
Cross Bars 6 mm & 8 mm square twisted
Mesh Sizes (Pitch) 30 / 33 / 35 / 40 / 41
Panel Sizes 5000, 5700, 6000, 6100

Surface Finish Options

  • Mill Finish
  • Painted
  • Hot Dip Galvanised (HDG)
  • Customization

Gratings can be customized in terms of size, load capacity, mesh configuration, and surface finish to meet specific project requirements.

Standard Pattern

Rectangular pattern gratings are most commonly used, typically with:
Bearing bars spaced at 30–40 mm (C/C)
Cross bars spaced at 40–50 mm (C/C)
