Tough. Durable. Versatile.
The performance characteristics of vitreous enamel result in a material that will not rust, is resistant to chemical attack, abrasion and fire as well as being more durable than any other architectural cladding material. In addition its versatility enables custom designs of all shapes and dimensions, the use of graphics and logos as well as a virtually unlimited colour range.
Durability
Vitreous enameled steel panels are extremely durable and need very little maintenance and cleaning. They will retain their original colour throughout the normal expected life of a building. Exposure to extreme weather conditions and coastal environments does not affect their performance or appearance.
Chemical Resistance
Vitreous enameled steel is resistant to all organic solvents and has excellent resistance to atmospheric pollution, corrosion and degradation by the great majority of chemicals. It will not rust and is 100% water resistant.
Abrasion Resistance
Vitreous enameled steel is extremely abrasion resistant withstanding cleaning and most abrasive materials without affecting the coating. It will meet scratch resistance to Moh Scale 6.
Fire Proof
Vitreous enameled steel is totally incombustible, will neither ignite nor burn and will withstand continuous temperatures of up to +400┬░C. Architectural VE panels will, depending on the design and the nature of the backing materials, provide fire ratings of a min. of two hours. Higher fire ratings can be achieved.
Graffiti Resistance
Vitreous enamel panels have a non porous and solvent resistant surface making them ideal for use in public areas where unwanted graffiti, markers and sprayed paints can be easily removed.
NO FADING – UV Light Resistance
Vitreous enameled steel is completely resistant to ultra violet light and the original colours and surface finish will not deteriorate under continuous exposure to sunlight.
Impact Resistance
The physical strength of the steel, coating and panel backing enable vitreous enameled panels to withstand deformation and damage due to impact, chipping and surface damage. This is provided they have been correctly designed, manufactured and installed.
Thermal Shock Resistance
Vitreous enameled steel will withstand rapid cooling by water spray from +400┬░C to normal room temperatures over a 30 second period.
Safety
The resistance of vitreous enameled steel to impact and distortion under extreme temperatures provide further significant safety advantages in applications such as tunnels and claddings in public areas.
Colour Range
The range of colours for vitreous enamel is virtually unlimited. Existing colours can be matched which makes it ideal for refurbishment or replacement panel. If a hard sample cannot be supplied for matching we can reference the RAL Design or Pantone color ranges.
Appearance
Vitreous enameled steel is sterile, germ free, odorless and easy to clean. Combined with its other characteristics and a smooth colour fast surface, vitreous enameled panels provide unmatched visual appearance.
Hygienic
Non porous finish that doesnΓÇÖt absorb bacteria and or allergens. Non stick, high gloss surface is very easy to clean. High resistance to cleaning chemicals and high abrasive resistance withstanding very intense regular cleaning with no loss in performance qualities.
Custom Designs
Vitreous enameled panels can be made in various shapes, sizes and configurations. Contact our Technical Advisory Service for further information.
Signage & Graphics
Logos, names and selected graphics can be fired onto the panels ΓÇô these will have the same characteristics mentioned above and will maintain their appearance throughout their life.
Secure
VE Doors create lockable compartments for services, utilities, cleaning or tool storage as part of the cladding layout.
Sustainability
VE Coating increases the lifespan of the original steel many times over reducing the need to produce replacements. Both the VE steel and the vitreous enamel coating can be recycled and re-used to make VE panels again.
Economical
VE has a lifespan at least 4 times that of most other cladding products. It is the most durable and longest lasting surface coating. It is also non fading and has the highest abrasive resistance making it not only cheaper but looking better over its lifespan.
