1. Describe the perforation pattern
Identify the hole or slot shape, nominal size and arrangement. State the pitch—the center-to-center spacing between adjacent openings—and indicate whether the pattern is straight, staggered or another layout. For a custom pattern, attach a dimensioned drawing or CAD file and mark the intended orientation.
Pattern details should be checked together with the selected material, thickness and manufacturing route. This guide does not prescribe a minimum hole-to-thickness ratio or promise that every pattern can be produced.
Pattern information to include
- Hole/slot geometry and size, including units.
- Pitch and pattern arrangement.
- Unperforated borders, margins and any blank zones.
- Open-area requirement only if defined by the project team, including how it is measured.
2. Define panel size and edge construction
State the finished panel width and length, quantity, edge returns and corner conditions. Show the hole pattern relative to the panel edges, not just as a repeated field with no origin. Note any alignment requirement between adjacent panels or with lighting and other ceiling services.
For formed edges or a perimeter frame, attach a section drawing. Confirm whether dimensions refer to the sheet before forming or the finished outside dimensions. Any tolerances, flatness requirements or joint gaps should be shown on the project documents and reviewed for feasibility.
3. Record material, finish and visible face
Specify the required material and grade, thickness, surface finish and color reference when known. Identify the visible face, coating coverage and any backing or acoustic infill included in the proposed construction. A sample or approved finish reference can reduce ambiguity, but the final supply scope should still be written down.
Open area is a geometric property of the perforated field; it does not alone establish sound absorption, airflow, strength or another project performance. Those outcomes depend on the complete design and applicable evidence.
4. Coordinate the ceiling interface
Show the support/carrier profile, panel engagement or fixing, retention expectations and joint details. Include cut-outs for luminaires, sprinklers, detectors and access panels. If an existing system is involved, supply its relevant drawings or a physical sample for review instead of assuming compatibility from a product name.
Perforated ceiling panel RFQ checklist
- Project use and environment.
- Hole shape, dimensions, pitch, pattern and orientation.
- Margins, blank zones and the open-area requirement, if applicable.
- Material, grade, thickness and finish/color reference.
- Finished panel dimensions, quantity, edge section and corner detail.
- Support interface, joints, service cut-outs and any backing.
- Sample approval, inspection points, packing, labeling and destination.
If information is unavailable, list it as a question for review. Do not infer production limits, standardized modules or acoustic ratings from a photograph or pattern name.
