This iconic Cell C building based in Midrand, Gauteng, South Africa, was built utilising ArcelorMittal galvanised steel for all the light steel frame construction and cladded with Chromadek, Charcoal Grey.

Hot-dipped galvanized sheets are produced on continuous zinc coating lines to the requirements of ArcelorMittal South Africa’s ISQ standards. The galvanising process yields homogeneously zinc-coated sheet with a bright, smooth metallic finish where corrosion resistance is needed without the cost of stainless steel.

CHROMADEK® is ArcelorMittal South Africa’s trade name for a range of colour coated sheet products that offer superior corrosion protection under conditions where the performance of unpainted galvanised sheeting may prove inadequate. Furthermore, the coatings exhibit excellent formability and elasticity to facilitate roll profiling and bending operations without damage to the paint coating.

Available in the following:

  • Decking (Galvanised)

Why Chromadek®

 

At inception, Chromadek derives its structural strength from its steel core, coated with a metallic zinc coating also known as the galvanised layer.

 

This layer ensures that both the structural integrity and steel core are preserved for functionality.

 

Once the longevity of the steel core is secured by the metallic zinc coating, Chromadek is aesthetically enhanced.

 

This, linked to the African Heritage colour range, makes Chromadek an instantly recognised colour-coated steel roofing option - an excellent choice in style.

Advanced technology roofing

Advanced Technology

 

Advanced thermal technology paint system incorporates a heat reflective pigment that provides up to an 8 degrees Celsius cooling effect and improved durability. Any Chromadek® roof in the heat reflective colours (Aloe Green, Buffalo Brown, Dark Dolphin or Charcoal Grey) can become cooler when exposed to the sun as it gets hotter.

Resistance Roofing

Resistance

 

The oven-cured paint system has been specifically developed for the harsh African sun. It is designed to provide resistance to fading, blistering and chalking as well as fluctuation from the natural elements of heat, cold, hail and UV rays to which a roof is exposed.
