Which cylinder fits your application

The right cylinder depends on how it will be filled, carried and stored. These are the four patterns we build for most often — if your application sits between them, our technical team will size it with you.

Domestic cooking

Household cylinders in the 3–15 kg range, sized for single-family cooking and designed to be carried by one person. Valve choice and collar design follow the refill infrastructure in each market, which is why our Ghana and Côte d'Ivoire specifications differ.

Commercial & hospitality

Larger cylinders for restaurants, bakeries and hotels running continuous burners. These prioritise refill cycle life and fast valve changeover, since downtime costs the operator directly.

Industrial & bulk

High-capacity cylinders for process heat, forklift fuel and industrial burners. Specified against higher test pressures and inspected to the standards your sector's auditors expect.

Camping & portable

Compact, lightweight cylinders for leisure and portable appliances, where handling weight and puncture resistance matter more than capacity.

Built and tested to recognised standards

Every cylinder leaving our lines is tested before dispatch. These are the standards buyers ask about most often — our Quality page documents the lab procedures behind each one.

  • ISO 4706 — welded steel LPG cylinders: design, construction and testing requirements.
  • DOT / EN specifications for cylinders destined for North American and European markets.
  • Hydrostatic and pneumatic pressure testing on every production batch.
  • Weld integrity inspection and radiographic checks on representative samples.
