140mm x 140mm Column Cases

Mezzanines are an effective means of creating additional space within a building. 

Building regulations require majority of mezzanine floors to be fire rated making them safe for staff, customers and storage. 

Rockliner provides the answer with a fire rating of up to 60 minutes for the full range of SHS sections. Its robust finish and decorative range make the system a perfect choice for various environments and uses.

Rockliner is available in leather grain colour ranges.  Galvanised and food-safe finishes are also regular applications. 

The system comprises a pre-formed metal encasement lined with Spiralite to provide the fire rating. It is installed using a snap-lock method for a strong and stable installation.

Casing thicknesses vary according to the fire rating and the steel sizes. Our technical support advises on design and lining thickness length to ensure the installation is correct.

Rockliner has been independently tested and assessed by BRE to British standards in accordance with the 5^th edition of the ASFP Yellow Book.
