MasterFrame 24mm Heavy Duty Exposed Grid System


24mm flange exposed ceiling grid system designed for heavy duty applications according to ASTM C-634. Tested up to 24.1kg/m.

Recommended for 

    • commercial, industrial and institutional projects with large ceiling spans
    • heavy boards – calcium silicate, perforated gypsum




MasterFrame HD is a T24 exposed grid system designed for heavy duty applications according to ASTM C-634. 

Tested to achieve a ceiling load of 24.1kg/m without mid-span deflection exceeding 3.33mm (L/360 on 1.2m hanger spacing).

Manufactured from hot-dipped galvanised steel complying to BS2989 and JISG3302 with Z18 zinc coating (180g/m2).

With the proprietary fire expansion slot on the main tees and the fire nibs on the cross tees, the system is designed to provide expansion relief in case of a fire. This feature maintains the structural integrity of the ceiling grid as long as possible, and helps to prevent acceleration of fire through the ceiling plenum and prevent injury due to falling projects during the evacuation process.
