About Superlit

Innovating for the future

SUPERLIT use cutting edge technology to manufacture world-class GRP pipes for future-facing infrastructure projects. As one of the world’s leading manufacturers, SUPERLIT’s GRP pipes are manufactured through a Continuous Filament Winding (CFW) or Centrifugal Casting (CC) process.

In the Continuous Filament Winding (CFW) process, the GRP pipes are constructed using orthophthalic or terephthalic unsaturated polyester resin. From there, SUPERLIT’s GRP pipes are manufactured from continuously flowing glass fibres that are winded on an automatic machine. By using continuous fibres in this process, the GRP pips produced feature quality material properties in terms of strength, stiffness, and durability.

Using the latest computer technology, Central Casting ensures raw material distribution and raw material consumption are kept under control and reported using real-time data until the pipe comes out of the mould. Manufactured with materials such as glass fibre, polyester resin and silica sand, the pre-programmed, automatically controlled process ensures that castings acquire high density, high mechanical strength, increased product purity and better production costs.
