Compound Steel Grating

Compound steel grating joins a load-bearing grating base to checkered plate or another steel plate layer. The combination keeps the structural logic of bearing bars while closing part or all of the opening to reduce small-object fall-through and create a more continuous walking surface.

  • Grating base plus checkered or solid plate
  • More closed surface for small-object containment
  • Added plate weight included in the support review
  • Ventilation, light and drainage reduce as coverage increases

One panel, two structural roles

The grating base carries load to the supports; the attached plate changes the surface. Full plate coverage provides the most continuous top, while partial coverage can retain open areas for drainage or access. Plate layout, seams, fixing details and cut-outs therefore belong on the approved fabrication drawing.

The trade-off is direct: plate adds self-weight and reduces the airflow, daylight and drainage that make open grating useful. The complete assembly—not the grating base alone—must be checked against the support layout, handling method and operating environment.

Variants

Recommended Types

Full plate coverage

A continuous plate covers the grating base; self-weight, drainage and lifting requirements are confirmed with the support design.

Partial plate coverage

Plate is limited to defined traffic or containment zones so selected areas of the grating remain open.

Cut and banded compound panels

Openings, notches and perimeter banding follow the approved layout and panel-number schedule.

Fabrication & QC

Fabrication & Quality Notes

  • Plate coverage, seam location and attachment pattern follow approved drawings.
  • Cut-outs are coordinated through both the plate and grating layers and fully banded where required.
  • Panel lifting and bundle weight are reviewed because the plate increases unit weight.

Packaging

Packaging & Delivery

  • Packing method is selected from strapped bundles, pallets or steel frames according to panel type, finish and site handling.
  • Panel tags and packing-list references follow the approved layout numbering when a project panel schedule is supplied.
  • Container loading is calculated per shipment from panel dimensions, bundle weight, packing method and destination limits.

FAQ

Compound Steel Grating FAQs

Why use plate over bar grating?
The plate creates a more continuous surface and can reduce small-object fall-through. It also adds weight and reduces drainage, light and airflow, so coverage should follow the actual requirement.
Can only part of a panel be covered?
Yes. Mark the required coverage, seams, cut-outs and traffic areas on the drawing so the partial layout can be confirmed before fabrication.
How is the compound panel specified?
Provide span, loads, support layout, plate coverage, surface pattern, material, finish, panel dimensions, cut-outs and quantity. Final construction details are confirmed per project.
