Specifications and technical data of grille BA – ¾



9,5 mm x 3 mm x 19 mm
(3/8” x 1/8” x 3/4”)
The bars of the grille are T-shaped and made of aluminum 6061-T6.
Specifically designed for floors with limited thickness (less than 25 mm (1″) and is built economically. Each grille is supported at 600 mm (24″) intervals by an invisible support installed under the grille for grilles that do not exceed 760 mm (30”) in length. For a grille of greater size, an intermediary support must be installed for regular installation.
Maintenance of grille is quick and easy.
Recommended for all kinds of buildings.
