RCM Series FRM Series PM Series CM Series RB Series XE Series PVC Fills Pultruded Profiles
 
 
 
 

A Pultruded composite profile is a combination of two or more materials, where the resultant material is superior to the individual component parts. STRONGLITE COMPOSITES’S product utilise these enhanced properties to the full.

Designed by an experience and talented team who know and understand composites, and manufactured by most advance techniques. Our products offer durable, long solutions at competitive price.

Pultruded Profiles have a wide range of application usage i.e. Cooling Towers, Work Platform / Pultruded grating, Bridge Decking, Ladders, Staircase, Cable Trays, Hand Rails, Structural Beams, Scaffolding, Tank Support, Fencing, Racking, etc.
Major Features and Mechanical Properties are shown below;
  * High Strength to Weight ratio.
  * Light in weight (approx. 25% of the weight of steel & 70% of the weight of Aluminium)
  * Easy to carry & transport.
  * Easy & fast installation
  * High Corrosion resistant.
  * Low electrical & Thermal conductivity.
  *
Ease of fabrication & User friendly (i.e. can be fabricated on field using simple carpenter tools, no torches or welding required)
  * Reduces life cycle maintenance cost
The tables below enlist the properties of Pultruded FRP structures v/s other structural material that are commonly used in cooling towers today.
