MVA Metal Ventilation Grilles
MVA is a range of metal grilles. The mounting frame is its unique feature. By using a flangeless mounting system, the grilles will fit into any mounting holes, even those with irregular shapes. MVA products are made from galvanised-steel sheet. Depending on the version, the grille fronts are available in stainless steel or galvanised steel versions with extra epoxypolyester coating.
