Porcelain enamelled steel or aluminium boards can be used for outdoor advertising, shop signs, road signs, house name and number plates, floor numbers in multi-storied buildings, danger boards for electrical pylons, and for a number of other uses. The main advantage of enamelled boards is its durability- painted shop signs or road signs start to fade after a few years, but enamelled boards last a lifetime without fading. Enamelled white boards are used for writing at office conference room and at institutional conferences. Enamelled green boards have largely replaced blackboards at schools and colleges, because chalk writing on green boards is much more clearly visible over long distances than white on blackboards. aluminium enamelled boards have the additional advantage of lightness and flexibility. Aluminium enamelled partition walls for offices can be colourful and attractive, and are much more resistant to fire than plywood or plastic boards. Curtain walls are walls where the outer brick wall of a multi-storied building is replaced by enamelled boards. Using a double curtain wall with a foam layer in between can reduce air conditioning costs in a building by as much as 40%. These curtain walls never require repainting. They will have the appearance of opaque glass, but because of the steel or aluminium base, may chip, but will not shatter if a stone is thrown at the wall!
