Notched and cut-out panels
Openings for columns, pipes or equipment are dimensioned, cut and banded to the approved drawing.

Custom Irregular Grating
Custom irregular grating turns a layout drawing into numbered panels around columns, pipes, vessels, curved edges and non-square boundaries. The page is the route for work that does not fit a standard panel: send the geometry, span direction and operating requirements so feasibility can be confirmed before pricing.
- Notches, cut-outs, curved edges and non-rectangular panels
- Drawing review before fabrication and coating
- Panel numbering matched to the approved layout
- Minimum openings and edge details confirmed per project
Made to drawings Irregular geometry Panel numbering Feasibility first
From layout geometry to panel numbers
Custom fabrication starts with the support layout and bearing-bar direction, then divides the area into panels that can be fabricated, coated, packed, handled and installed. Every notch, opening, curved edge and boundary needs a clear dimension and reference point; site-trim assumptions are avoided wherever accurate drawings are available.
The review also sets practical limits. Narrow strips need enough structure for banding, openings need clearance for fabrication and the selected coating process, and large or awkward shapes may be split into smaller numbered panels. These limits are confirmed on the drawing rather than hidden inside a standard-panel table.

Custom Irregular Grating in Detail
Project-fitted ring assembly
One continuous ring, built from drawing-matched segments
When grating must follow the perimeter of a tank, vessel, column or another circular structure, standard rectangular panels do not match the required footprint. We divide the annular area into practical fan-shaped panels designed for that specific position in the project.
Before delivery, the complete set is laid out in the workshop to check the inner and outer curves, joint alignment and overall fit. Panel references can then follow the approved layout so each segment reaches its intended installation position.
- 01
Define the annular zone
Inner and outer diameters, support locations and bearing-bar direction determine how the circular area is divided.
- 02
Fabricate the fan-shaped segments
Each panel is cut and banded to the approved radii and radial joint lines rather than trimmed to shape on site.
- 03
Trial-assemble and identify
The full set is laid out to check curve continuity and joint sequence, then panel references follow the installation drawing.

Fabrication & Quality Notes
- Send PDF, CAD or a dimensioned sketch with support steel and bearing-bar direction marked.
- Show every opening, radius, notch, edge condition and required clearance.
- Panel splits, banding, lifting and numbering are returned for approval before fabrication.
- Final dimensions and minimum opening details are confirmed per project.
Packaging
Packaging & Delivery
- Each panel is tagged to the approved layout number.
- Irregular edges receive packing protection and panels are bundled in installation sequence.
FAQ
Custom Irregular Grating FAQs
Which drawing format should I send?
PDF or CAD is preferred, but a clear dimensioned sketch can start the review. Mark supports, bearing-bar direction, openings, radii, panel boundaries, loads and finish.
Can narrow cut-outs be hot-dip galvanized?
They require review because zinc can bridge narrow clearances. The workable opening, banding detail or a split-panel alternative is confirmed per project.
How are irregular panels installed in the right place?
Approved fabrication drawings assign a panel number to each shape. Tags and packing sequence follow that schedule so site teams can match panels to the layout.
