Our new activity since 2010 is the development of a cost effective and eco-friendly LPG composite cylinder (TYPE IV) manufacturing line through replacing outdated thermal curing systems with futureproof UV-technology (international patents pending).


Composite LPG cylinders Type IV, consisting of glass fibre reinforced plastic liner (patent p.), boss (patent p.), pressure valve and plastic casing offer a lot of advantages in comparison with steel cylinders:

Maximum Safety

  • No explosion risk under fire or bullet shot, suitable for domestic, leisure or industrial use
  • Designed to meet European and international standards
  • No rust


  • Gas level is always visible thanks to translucent properties
  • Convenient handling stacking and cleaning due to ergonomic design
  • Modern, customizable design with attractive branding opportunities on the cylinder casing

Lightweight *

  • Up to 70% weight reduction with same tank capacity

Environmental friendly

  • Recyclable
  • Reduced logistics and maintinance costs *

All these properties together with the attractive and modern design assure LPG composite cylinders a great worldwide market acceptance and potential.
Composite LPG cylinders (thermally cured) are already successfully used in many countries.

COIA provides 1st LPG Composite Cylinders Manufacturing Plant to the UAE
