  • Chromadek Roof Sheeting

Chromadek roof sheeting is available as either Chromadek® Standard or Chromadek Ultim® designed for exposure and use in different atmospheric conditions.

Standard Chromadek®roof sheeting
  • Is intended for use under rural, Industrial (mildly chemically polluted) or moderate marine conditions.
  • Comprises a Z200 hot-dipped galvanized substrate pre-primed with a primer (Dry film thickness (DFT) of 5µm) and finished with a final paint coat (DFT of 18 – 22µm) on the top surface.
  • A single backing coat (DFT of 8µm) is normally applied to the reverse side of the sheet
Versatile and Aesthetically Pleasing

Chromadek® offers great versatility for roofing and cladding applications. South African architects use Chromadek® in a variety of roofing and cladding projects ranging from churches, shopping malls, factories, warehouses and airports to luxury eye-catching homes and large housing estates.

Chromadek® is exceptionally colour-fast. Warranties are given on application, subject to certain conditions. The 14 exciting colours in African Heritage Range captures the essence of the African environment reflecting the continent’s unique hues allowing designers the freedom of expression.


Steel is generally regarded as a rigid material offering only strength. This is not true of the galvanised steel used as a substrate for Chromadek®. It is readily formable which makes it eminently suitable for a wide variety of end-uses in the building industry. The formability of the substrate is matched by the flexibility of the paint system, two characteristics desired by architects, profilers and developers.


Chromadek® is lighter and stronger than any other roofing material, providing roofs of up to 80% lighter than those using concrete tiles. This saves on the roof structure, construction time and equally important the cost.

The importance of the steel substrate

In light of certain colour coated steel product not reaching the expected life span, it is clear that all colour-coated steel sheeting does not comply with the design requirements for structural roofing materials. Due to Chromadek® being a well-established brand name, the name is being used generically for pre-painted roof sheeting. Authentic Chromadek® sheeting is imprinted with “ArcelorMittal South Africa Chromadek®” at regular intervals to mark it as the genuine colour coated steel product manufactured by ArcelorMittal South Africa.
