We make every effort to cut down the rust factor when making and installing our blinds. Most of the hardware we use is galvanised, aluminium and stainless steel as we know what happens when things are outside in our harsh Aussie climate. If we are near the ocean then we will recommend stainless steel fittings which may cost a little extra but will stand the test of time. Our installers are full bottle on the right fitting for the right location. The actual fabrics used have no metallic content and therefore no risk of rusting what so ever.
