Every corner is joined flat on the floor
Coffers are assembled and checked against a straight edge before packing.
If skippedCorners cut separately arrive open, and grazing light from the reveal shows every one.

The harshest inspection position in a building: close range, grazing light, and no shadow to hide a corner in.

01
Ceiling systems
A ceiling is seen from below, at close range, with lighting designed to graze it. It is the harshest inspection position in a building.
Two systems: flat panels with a shadow gap between them, and coffered panels where the recess itself carries the lighting. Both are made of folded sheet; both are decided by what happens at the corners.
Coffered
Each coffer is pressed or folded with four returns, then joined at the corners. The lighting channel sits in the reveal, which means the reveal is dimensioned from the fixture, not from a nominal.
Flat with shadow gap
Panels on a concealed frame with a constant gap. Simpler to make and harder to get right, because the gap is the only feature and any variation reads as a mistake.
02
The specification
| Property | Figure | Note |
|---|---|---|
| Thickness | 0.8–2.0 mm | Thicker is not better; a heavy coffer needs heavier support for no visual gain |
| Panel size | Up to 1500 × 4000 mm flat | Larger coffers are made from joined sections |
| Corner gap | 2 mm ±0.5 mm | Measured at every corner, not sampled |
| Flatness | 1.2 mm / m | Checked on a straight edge; ceiling lighting shows waves |
| Lighting channel | From the fixture drawing | Never from a nominal dimension |
| Fire | Non-combustible (steel) | Confirm with your local code officer; the frame may need its own rating |
| Access | Designed per panel | Ceilings need access above them; decide now, not after installation |

What decides a ceiling
The lighting channel comes from the fixture
We ask for the actual fixture drawing and dimension the reveal from it.
If skippedA 5 mm error means the fixture does not fit, and the reveal is opened up on site with a grinder.
Access is designed before fabrication
Access panels are drawn and made as part of the system.
If skippedThe ceiling is closed, and the first service visit cuts a hole in it.

we will talk about the joints.
Grade and finish are a specification. Whether two panels meet cleanly, in one colour, with no cutting on site, is the job.
