Gastronorm is a standardisation system used to normalise and classify the dimensions for containers and trays used in the food industry. In this article, we take an in-depth look at the Gastronorm system – its origins, meaning and purpose. Read on, and you might be surprised at the influence of this standardisation on your kitchen and catering equipment.


The origin and purpose of Gastronorm standards

It all began in the 60s when a group of researchers from Switzerland met to declare dimensional standardisation for kitchen utensils such as pans and trays. At the time, the 530 x 325 mm dimension was already a standard for pans in the U.S. The researchers adopted this dimension as the new Gastronorm-Normal standard (as it was initially called).

Although the Gastronorm standard was originally intended for use in Switzerland, other European countries quickly adopted it. Today, Gastronorm a worldwide modular standard.

The Gastronorm standard allows spatial optimisation in the design of the kitchen and catering utensils and appliances. It helps establish industrial manufacturing standards for items such as ovens, dishes, sinks, refrigerators, dishwashers, and storage compartments. Spatial standardisation enables easy equipment and crockery compatibility and identification.


Gastronorm sizes

The standard Gastronorm size, also known as Full Gastronorm is 530 x 325mm. Eight more Gastronorm sizes are derived from this dimension. Any product in the EU region that states a Gastronorm size must abide by one of the following dimensions as stipulated by the European Standards Committee.

  • GN 1/1 – 530 x 325mm (Full GN)
  • GN 2/1 – 650 x 530mm (Double GN)
  • GN 2/4 – 530 x 162mm (Two-Quarters GN)
  • GN 2/3 – 354 x 325mm (Two-thirds GN)
  • GN 1/2 – 325 x 265mm (Half GN)
  • GN 1/3 – 325 x 176mm (One-third GN)
  • GN 1/4 – 265 x 162mm (Quarter GN)
  • GN 1/6 – 176 x 162mm (Sixth GN)
  • GN 1/9 – 108 x 176mm (Ninth GN)

These are only the length and width measurements. The depth determines the capacity or the container — manufacturers design Gastronorm containers with varying depths for various applications. The depth and capacity are always stated in the product description; like this – GN1/1-100, 12.6-litre capacity.


Types of Gastronorm pans and trays

Gastronorm containers are commonly used in commercial catering for cooking, food preparation, buffet displays, chilling, and storing food. A container’s application is mostly dependent on the material it’s made of. Below is a description of some of the various types of Gastronorm containers and their uses in the catering business.


Stainless steel Gastronorm trays

Stainless Steel Gastronorm PanStainless steel gastronorm pans are the most versatile Gastronorm containers and are used for a variety of applications. These pans are robust, durable and excellent conductors of heat, making them ideal for oven cooking, and deep chilling.

Their polished shiny surface and heat retention properties of steel make the stainless steel pans great for buffet displays. In fact, most chafing dishes and bain-marie are designed for various sizes of stainless steel Gastronorm trays. And the beauty is, the food may come straight from the oven to a buffet without changing pans.

With a lid on, a steal Gastronorm pan can also be used to store food in a freezer of refrigerator.


Polycarbonate Gastronorm pans

Polycarbonate Gastronorm Pans

Gastronorm container can also be made from Polycarbonate or Polypropylene materials. Polycarbonate Gastronorm pans are mostly used in food preparation, chilling and buffet displays.

However, these pans are not good conductors of heat, which means they are not suitable for chaffing dishes or cooking. They are used to hold cold or chilled servings such as salads, puddings and fruits.

Unlike stainless steel pans, polycarbonate pans can be microwaved. They also remain cool to the touch even when holding hot or freezing food. They are also much better than steel pans at storing and freezing food. This is because they come with tightly fitting lids, and most of them are transparent – so, you don’t have to open the cover to see what’s inside.


Melamine

Melamine gastronorm pan

Melamine is a hard, lightweight material that closely resembles ceramic. It’s made from thermal setting plastic strengthened with melamine resin.

Gastronorm pans made from melamine should only be used to hold cold, chilled or lukewarm food. Melamine pans don’t fare well in high temperatures from any source, including microwave ovens and conventional ovens. The problem is, melamine starts to dry out when exposed to a lot of heat, which cause it to turn brown and form cracks.

These trays can, however, be used to chill and store food.


Other accessories

Besides lids, Gastronorm pans also come with a variety of corresponding accessories. Some of which include, Gastronorm grills, baskets and drain plates. These accessories are sized according to Gastronorm dimensions and are built from various materials such as stainless steel, plastic, and polycarbonates.
