Vitreous enamel has proven to be a suitable material for hostile environments. A major advantage of vitreous enamel signs is that it allows an image to be printed onto a pre enamelled surface with which it chemically bonds. This results in a sign that can be sited in harsh conditions, and which will easily outlast any other sign type. Insign Graphics provide vitreous enamel signs.

Vitreous enamel signs retain their integrity and image long after other signs. Other advantages include ease of graffiti removal, tolerance to climate extremes, high scratch resistance surfaces and colours that will stay vibrant for over 25 years.

Colour photographs, logos, maps and line drawings can be incorporated within the process. Vitreous enamelled signs are ideal for heritage and interpretive projects, walks, wayfinding and general information signs.
