Driven by innovation

We have developed a unique technology that enables us to produce seamless composite cylinders. Our fully-automated manufacturing process is comprised of three main steps:

Step 1

An inner liner of polyethylene (HDPE) is blow-molded.

Step 2

Glass fibers and resin are then wound around the liner to create the pressure vessel.

Step 3

To provide even greater support and bring an element of design, we add an outer layer in the form of a polyethylene (HDPE) casing. This distinctive casing, with trademarked design, provides both protection and an ergonomic grip. It also allows our customers to brand their cylinders.

Our entire process is done in-house and fully automated – starting with the raw materials through to the completed cylinders on pallet ready for shipment, making our cylinders, the most efficiently-produced and quality consistent composite LPG cylinders in the world.

During the manufacturing process, there are more than 35 points where production data on each cylinder is collected and stored for full traceability.

Our standards for design and manufacturing of composite cylinders

  • ISO 9001: Quality Management System Standard
  • ISO 14001: Environmental Management System standard
  • ISO 50001: Energy Management System standard
