What is a Gastronorm? A brief history.

Often referred to as GN, Gastronorm is the term for a tray, container, or pan that has been made to an exact size specification for the catering industry.

The concept originated from Switzerland in the seventies and was soon adopted by the British Standards Institution.

This easy-to-follow sizing system brought a simple and measurable way to maximise oven or refrigerator space, ensuring that every bit of space is used efficiently whilst cooking and storing foodstuffs.

For manufacturers of kitchen machinery (ovens, fridges, etc) and kitchen accessories, trays, containers and so on, the Gastronorm system brought a uniform size guide to ensure their products are built for efficient cooking or storage.

Currently, Gastronorm systems are used for so much more. The size specs are now used in the building of deli-counters, hot buffet equipment, microwaves, and in fact for most catering appliances where the cooking/ storage of food is involved.

Types of Gastronorm

Gastronorms for roasting, baking or hot-food buffet service are often made of aluminium or stainless steel and may be perforated if they are to be used for steaming, or if air-flow for even cooking is required.

Cool-counters or refrigeration units may require GNs made of toughened glass, melamine or other composite plastics.

Finally, there are also disposable types made from aluminium foil, or other single-use materials.
