General details:
Elefant Gratings operates with 8 universal fixing methods for our louvre gratings.

Further, we have developed special fitting methods for individual projects on several occasions in collaboration with clients, architects and consulting engineers.

Fixing plates:
Fitting plates are welded between the bearing bar and the edge bar 3 mm from the underside of the grating.

They are available with round or slotted bolt holes. The angled louvre bars are removed locally where the fixing plate is positioned.

Fastening with bolt holes or notches in edge bar:
Elefant® gratings can be fixed using bolt holes in the edge bars. Another suitable method for fixing louvre grating are notches in the edge bar.

Bolt holes in the edge bar can be used for louvre gratings with normal edge bars and for louvre gratings with deep edge bars.
Notches in the edge bars can only be used for louvre gratings with deep edge bars.

Bolt hole sizes:
The standard bolt hole sizes are:
Round: Ø6, Ø8, Ø10, Ø12 mm
Slotted: Ø9x15, Ø11x28, Ø14x28 mm
Other hole sizes can be made to order.

Fixing of louvre gratings with hidden fixing plates:

This fixing method consists of plates welded flush to the rear. At the same time, round or slotted bolt holes are made in the louvre bars so that the fixing plate is hidden behind. When mounted, the bolt is placed through the hole in the inclined louvre bar down into the fixing plate. In this way, an almost hidden fixing of the grating is obtained.

A different variant of this type of fastening is also available. This is a semicircular holenotch from the outer edge to the middle of the louvre bar.

The above methods are recommended if the gratings are used in an aesthetic application, requiring the fixing to be discreet.However, they require that the fixing holes are adjusted to fit within the configuration.
