They are particularly suitable for public buildings, halls, car showrooms, corridors, etc. Each slat is separated by steel spacers and the entire product is lacquered in the same colour, as standard RAL 9006 (grey) powder coating. Other RAL colour chart colours are, however, available on request.

Load bearing capacity

PM-graf

In load-bearing capacity testing, grille slats are placed on two supports and weighed down in the center.
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 U-shaped and F-shaped frames are available as standard in aluminium with silver, black, dark bronze or light bronze elox finishes. U-frame, Thin and Cross frames are also available in black elox. 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.
