Rocklite® ‘I’ Hinged Fire Doors

Manufactured to SANS 1253:2003 (edition 3) and stringently tested by the SABS over the years with a proven fire protection rate of two and a half hours. ROCKLITE® fire doors have many other advantages over traditional fire doors. (Test Reports are available on both our ROCKLITE® single fire doors as well as our ROCKLITE® double fire door assemblies).

​

ROCKLITE® fire doors are lightweight, weighing only 29kg per standard size panel, and are easy to install. They are manufactured in a wide range of sizes and veneers to match existing surfaces.

 

ROCKLITE® fire doors are supplied with a purpose-made 1,6mm steel frame with a 25mm rebate including one and a half pairs of brass hinges. Frames can be manufactured to suite all wall requirements including existing wall openings and partitions.

​

Constructed with an inner monolithic, asbestos-free, fire resistant core, ROCKLITE® fire doors have reinforced steel inserts strategically located within the core material to strengthen hinging and hydraulic closure attachment.
