The standard writing surface of our Chameleon Writing panels is made of high-grade white enamelled steel (fired at 800°C). This ensures that our panels have an excellent service life and are suited for very intensive use. Indeed, we offer a 25-year guarantee for the writing surface of our standard panels. In addition to white enamel, we also offer options like chalk-grey or green, a projection surface or printed surfaces. All these surface options are magnetic, easy to write on and dry-erasable.
