For supply or extract applications, the grilles are designed to integrate with the most popular raised access floor systems. Available in both Light and Extra Heavy duty grades to BS-EN 13264z2001.
Manufactured from heavy gauge aluminium extrusions, the frames are of fully welded construction. Extra heavy duty versions incorporate rear reinforcement muIIions to maintain fuII structural integrity.
The grille core is constructed from extruded aluminium bars with a face thickness of 6mm, and is welded into the retaining frame.
The frame profile is designed to sit directly in contact with the floor pedestal earth terminal, removing the need for additional earth bonding connections and their associated expense.
Independently tested by the University of Salford and at Building Testing Ltd, the R76 exceeds the requirements of BS-EN 132642001 for extra heavy grade structural classifcation in static load tests, rolling load tests and impact load tests.
