Extra heavy grade

FDEB_XH is our extra heavy grade system, capable of handling a 12kN/m2 uniformly distributed load. FDEB_XH is suitable for data centres with heavy equipment. This system is in use at HP's data centre in Wynyard, Stockton-on-Tees, UK.
Panel comprises of galvanised steel top and bottom sheets that are bonded to the core. A High Pressure Laminate surface is applied to the top surface and the panel is finished with a full edge banding.
We’ve invested in research and development to optimise our energy and raw material usage. This system has EPD & HPD certification and is manufactured in our advanced, energy efficient manufacturing facility where 94% of the energy used is from sustainable sources.
