” The dimension of directional diffusers here from read more the SI device is 595x595mm. If you place an Imperial unit directional diffuser (603x603mm) over a SI unit ceiling, it will not likely fit. Precisely the same applies to other squareshaped ceiling diffusers. Normal directional diffusers are made of aluminium. Galvanized steel directional diffusers are likely to rust.
