Bar grating panels
Panel extents, bearing-bar direction, edge banding, grating specifications and location marks.
Miscellaneous Steel Detailing
Steel Grating Detailing & Shop Drawing Services
Coordinated grating layouts, panel schedules, stair tread details and support interfaces for fabrication and site installation. We turn approved design information into clear, revision-controlled grating documentation.
Concept diagram only; final dimensions and fixings follow approved project specifications.

Technical scope
Grating drawings built around fabrication and fit
Steel grating packages need more than a general arrangement. Panel boundaries, bearing-bar orientation, clearances, penetrations and installation supports all affect fabrication and field placement. Our detailing scope is established from approved structural, architectural and vendor documents, with unresolved interfaces raised for review before issue.
Industrial platforms
Access walkways, maintenance floors, landings and supporting steel interfaces.
Stair treads
Tread profiles, nosing requirements, fixing arrangements and stair framing coordination.
Cutouts & openings
Penetrations at pipes, equipment, columns and other obstructions, including edge treatment notes.
Clips & supports
Specified fixing clips, attachment points, support bearings and adjacent steel details.
Other grating systems
Plank grating and fiberglass-reinforced polymer (FRP) layouts where manufacturer data is supplied.
Interface coordination
Details that need to agree across disciplines
Grating panel layouts are coordinated with structural support plans, access requirements and approved manufacturer information. Material selection, load capacity, allowable spans and fixing adequacy must be confirmed by the responsible design authority.
- Grating thickness, type, pitch and bearing direction
- Panel sizes, split locations and access clearances
- Equipment, piping and column cutouts
- Support framing, edge angles and bearing surfaces
- Specified clips, welded interfaces and corrosion-protection notes
- Stair tread, handrail and kick-plate coordination where required
Drawing package
Typical outputs
- Grating general arrangement and marking plans
- Panel and stair-tread fabrication details
- Dimensioned sections and enlarged cutout views
- Panel identification and material schedules

Material takeoffs, model exports and related steel details may be included when agreed for the project.
Project delivery
From design input to coordinated issue
Review inputs
Check structural plans, specifications, vendor catalogs and required drawing formats.
Develop layouts
Prepare panel boundaries, orientation, marks and support references.
Resolve interfaces
Identify clashes, missing dimensions and decisions requiring client approval.
Issue & revise
Prepare checked drawings and incorporate authorized review comments.
What to share
Information needed to begin
For an accurate quotation, share the grating area plans, structural support drawings, selected grating product, loading/design references, connection preferences, drawing standards and target issue schedule. Marked-up PDFs, DWG files or model extracts are useful starting points.
For design-related issues, the engineer of record or appointed design professional retains responsibility for design assumptions, compliance checks and final approval.
Frequently asked questions
Common project questions
Do grating shop drawings show individual panel marks?
They can include location marks, dimensions, edge conditions and a panel schedule when these are part of the agreed detailing scope.
Can the drawings include stair treads and access platforms?
Yes. Stair tread layouts, landings and platform grating can be coordinated with the associated supporting steel and approved details.
Who determines the grating load rating and span?
The applicable design authority confirms loading and structural adequacy using approved specifications and manufacturer data; detailing documents reflect those decisions.
What happens when equipment cutouts change?
Revisions are documented against updated inputs, with impacts on panel sizes, marks, support interfaces and schedules reviewed before reissue.
