Gastronorm

Porcelain bowls and plates in Gastronorm dimensions have a particularly elegant and appealing appearance and are therefore widely used, especially in food serving. GN containers made of white porcelain provide a visually appealing frame for the food on offer and are therefore quite different from their steel or plastic counterparts! A raw vegetable salad or a potato gratin in a porcelain container matures to a visual highlight and appears dull and musty in a tin container. Against this background, Gastronorm containers and Gastronorm plates are primarily used for so-called "front cooking", i.e. in the zones visible to the guest.

 

 

The GN plates and GN bowls from Holst Porzellan have a "flat base" and are therefore also ideal for placing on hot plates and hotplates.

In addition to the optical advantages, the practical advantages over other products made of CNS 18/10, CNS 18/0, polycarbonate and melamine should also be emphasized. Protein-containing foods and all milk-calcium compounds do not "draw" water into porcelain as quickly as into metal and plastic. A scrambled egg in a porcelain container waters out by a factor that is up to ten times less than in a metal GN container.

Mustard-containing sauces, some types of balsamic vinegar, most types of vinegar, as well as all acidic foods and sauces already cause considerable strain on colleagues made of metal and plastic during short storage periods. Pitting corrosion cannot occur in a porcelain container! Accordingly - but only a few experts know this - many dishes and food compositions in a porcelain GN container remain fresh and original in taste for much longer!

 



The specificity of Gastronorm in general

Every manufacturer and gastronomy retailer will quickly advise a gastronome that it is not possible to stack a "Rieber" in a "Blanco" or a "WHAT" Gastronorm container. Also Cambro and Rubbermaid do not fit into each other in all sizes. The expert certainly does not expect that plastic, polycarbonate, metal and chrome-nickel steel containers can be stacked together.

The recommendation "stay true to one brand" is a phrase that is often used in connection with stainless steel GN. The reason for this is well known. The standard "GN" only specifies the external dimensions (530 x 325 mm = GN 1/1). Cut-out dimensions, radii and clear heights (gap heights for drawers) are not covered by this standard and cannot be combined in one standard due to the wide variety of variations!

Unfortunately, these findings are often not applied in the consultation for GN porcelain. Occasionally inexperienced customers demand that GN porcelain dishes "can do everything" and must fit everywhere, but unfortunately this is not possible!

 

 

The advantages of GN-Porcelain

  • food safe (complies with strictest HACCP standards)
  • heat resistant (well over 300° C)
  • ovenproof
  • suitable for microwave
  • free of holes
  • corrosion-free
  • virtually unlimited life
  • easy to clean



The disadvantages of Gastronorm porcelain

  • more expensive than metal and plastic
  • high dead weight
  • not 100% stackable
  • not available in all GN sizes
  • high dimensional tolerances in the dimensions
  • not suitable for all GN-standard devices

 

Dimensions and tolerances by Gastronorm

According to the German industrial standard, the tolerance value for porcelain from a body thickness of 3 mm for a 26 cm plate is set at a maximum of +-7 mm. Larger (complicated) porcelain vessels are unfortunately not covered by the standard! Expressed as a percentage, a 26 cm plate may have production-related tolerances of up to 2.69%.

If this low tolerance value is adopted, a GN 1/1 container or 1/1 GN plate with a GN specification of 530 x 325 mm may be up to 544.3 x 333.7 larger, or up to 515.7 x 316.3 smaller. From a length of 532 cm or a width of 327 cm, however, a GN container begins to lose its multifunctional suitability.

In extensive tests we have found out that a container that no longer fits into a certain model of the Spring company can be used in a WMF chafing dish without any problems. The clearance in combination with the flange focal length of a chafing dish or a bain-marie (water bath) decides whether a container fits or not.

With the same application of a percentage deviation allocation we have found 62 mm dimensional differences, i.e. over 11% tolerances of different manufacturers of warming devices (in the test: Bartscher/Hepp/Contacto as well as two trademarks), starting from the inner point of a chafing dish to the outer point of the contact surface.

If one summarizes the functional areas of a GN container, a GN 1/1-65 mm, for example, must meet the following criteria in terms of accuracy of fit:

 

Laid up
(DIN-standardized)

ca. 530x325 mm Contact surface measurements
Hanging ca. 475x275 mm Input dimension
Placing ca. 440x247 mm Base plate
Setting
(DIN-standardized)
ca. 65 mm Container height
Setting up ca. 460x265 mm Bottom perimeter
Stacking ca. 475x270 mm Stacking edge
Stacking into each other ca. 435x240 mm Base Inner dimension
Juxtapose ca. 595 mm Diagonal length
Inserting ca. 10 mm  

 

So there are a total of 18 neuralgic values (lengths & widths) where the use of a GN container with a third device could fail. 

GN containers from Holst Porzellan

The Gastronorm tableware distributed by Holst Porzellan/Germany, i.e. all GN containers and GN plates, are tested to a dimensional accuracy of +- 4 mm and are therefore ideally suited for normal use in the hotel, catering and mass catering industries!

The GN porcelain from Holst Porzellan is heat-resistant, EU-compliant, edge-hit, robust and made of genuine, ovenproof hard porcelain. For more than 10 years, caterers, hotels & restaurants, as well as many canteen kitchen companies have been using GN Porcelain by Holst. Our GN-Porzellan goes to sea on well-known cruise ships, catered for winter sports enthusiasts in lofty heights and even made it to the Federal Chancellor's Festival! It is suitable for food preparation as well as for food transport and serving.

 

Warranty exclusion of special requirements for a special use

We ask for your understanding that, for the reasons mentioned above, we do not provide our GN porcelain with a guaranteed property for mass-dependent use in third devices! If in doubt, please test the suitability for use with a sample! Price tip: If you only want to use GN porcelain as "display trays", we offer a much cheaper alternative with our box moulds!
