A frame of galvanised steel: ceiling sections for a ceiling, and studs in a floor and a ceiling channel for a partition.
Common practice for a 12 mm board:
| Part | Spacing |
|---|---|
| Intermediate channels of a ceiling | 1220 mm |
| Ceiling sections | 457 mm |
| Partition studs | 610 mm |
| Board screws | 230 mm, and 150 mm at the edges |
The span and the load set the final spacing: use the span table of the section maker. A flat ceiling starts with a level frame. We make Metal-Max steel sections at Panvel.
