Material

Products manufactured in Radiant are made from Polymer Concrete and Epoxy resin, for indoor as well as outdoor electrical application.

With over 15 years of R&D Radiant has developed its own unique formulation of Resin called RE - RESIN .

The on-site performance and product acceptance of this Formulation speaks for itself.

Keys advantages of RE - RESIN
  • Suitable for outdoor environment as it is UV resistant.
  • Design Flexibility due to Metal Part mouldability & high strength.
  • Excellent Mechanical & Electrical Properties.
  • Very Good Impact, Shock and Vibration Strength.
  • Cannot be eaten by birds.
  • Very Good Freeze – Thaw properties.
  • Minimal moisture absorption.
  • Durability that reduces typical breakage from shipping, storage, and installation
  • Cracks do not propagate like Ceramic during impact.
  • Cannot be eaten by Birds or Insects.

RE - RESIN has gone through various test process across various parts of the world to gain global acceptance and presence.
