What is Chromadek®?

Chromadek® is ArcelorMittal South Africa’s trade name for a range of colour coated sheets. This high-quality product has been manufactured by ArcelorMittal in South Africa for more than 35 years.

Chromadek® is the roofing and cladding material of choice made by architects, designers, industry, and homeowners renowned for its aesthetic value, protection from the natural elements, and the ease of application complimenting any building. These key attributes have been developed spanning research years to prolong the useful life of the paint system and sheeting in the harsh South African climate, depending on the environment supported by the correct design, selection, installation, and maintenance. 

Chromadek® is produced by coating galvanized coated steel coil subject to stringent quality control standards on a continuous coil coating line. The galvanized steel is chemically cleaned and treated to enhance corrosion properties and paint adhesion. A primer which is cured in a prime oven is applied, followed by a top coat that is cured again to obtain its aesthetic and functional properties.

Chromadek® is available in a range of 14 standard colours based on a resin paint system consisting of Polyester/Polyurethane blends in specialised pigments ensuring corrosion resistance, durability and response to formability.

Standard Chromadek® is intended for use under rural, residential, industrial, or moderate marine conditions and comprises a Z200 hot-dipped galvanized substrate pre-primed with a primer and finished with a final paint coat on the top surface. A single backing coat is normally applied to the reverse side of the sheet.
