their composition, a metal pan ceiling can achieve different shapes and finishes that non-metal varieties cannot.
Following is a list of the types of grids and their most suited applications. More importantly the list will describe ways you can utilise metal pan with that associated grid to take your ceiling to places unseen in non-metal applications.
1.Lay-IN Aluminum Ceiling Tile
Above ceiling tiles lay on a T-shaped runner such as top-left. Right: NAB Docklands building utilises a perforated metal lay-in tile system.
The grid of a lay-in tile system is fully seen and is the most common product in standard office buildings.
Tiles are simply placed on a T-shaped runner (above left), generally between 10 and 25mm, and can be easily installed and demounted as individual tiles.
Cootes drew attention to the flexibility that lay-in tiles afford to maintenance requirements and services that need to access the ceiling void above the tiles.
“Lay-in tiles are extremely easy to remove and flexible for services such as electricians, plumbers, aircondition and that sort of thing,” he said.
“They are also the easiest to move around when renovating and shifting office spaces.

Ceiling tiles on a clip-in system do just that - they clip on to the suspended grid and therefore conceal the grid from view. Manufacturers have their own unique clip-in systems that match their boards but generally they all consist of a spring tee runner from which boards clip on to.
Cootes explained that clip-in tiles involve a special demountable tool to access the ceiling plenum and thus aren’t as convenient for services as a lay-in tile. They can, however, withstand upward cleaning pressure that lay-in tiles can’t, so cleaners can remove stubborn marks without damaging or moving the tile.
“An answer to their lack of accessibility however would be the hinged-down system,” said Cootes.
“The hinge-downs aren’t used throughout the whole ceiling, just in places that need to be accessed by services.”
