Advantages

Some of the advantages of our insulated modular panel system:
  • EPS is the most economic form of insulation.
  • Durability and high resistance to water absorption.
  • Aesthetically pleasing to the appearance. (Panels can be ordered plain or ribbed)
  • Low weight of the panels make for easy & speedy installation.
  • No specialized skill required for the installation.
  • Excellent insulation properties.
  • High strength to weight ratio.
  • Easily transported in kit form.

Technical Data

General desciption of Chromadek® for exterior application.
Over and above its aesthetic attributes, CHROMADEK paint coatings are designed to provide 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.

Chromadek is applied onto a galvanised coated substrate, which has been produced by the addition of Antimony and Aluminium to the molten zinc in the bath, to improve the formability and adherence of the zinc coating.

Excellent paint adhesion is achieved and corrosion resistance enhanced by careful preparation of the steel surface prior to paint application. Rigid quality control testing is carried out on each coil to ensure conformance to specification.
