Thin grilles are manufactured from eloxed aluminium and are designed solely for Thin trench heaters. They are only available as a roll-up model.

The standard finish for aluminium grilles is silver elox; in addition, dark and light bronze elox are available. Other RAL colour chart colours are available as powder coating.  Decorative Thin frame covers may be chosen using the same colour scheme as grilles, and are supplied as a component of trench heaters. Due to space limitations, F-frames are not available for Thin grilles.

Load bearing capacity

     Grafy PM

In load bearing capacity testing, grille slats are placed on two supports and weighed down in centre.
For wooden slats, values are given up to the fracture point of the first fibre. Metal slats are measured up to the point of irreversible deflection.

Decorative frames are available as standard in aluminium with silver, dark bronze or light bronze elox finishes. Frames may also be lacquered (powder coated) using colours from the RAL colour chart. Frames are in every case supplied as a component of trench heaters, and the type required must be specified when ordering in the Order Code. Where  trench heaters are finished with a hem, the hem is of the same material as the casing.
