GN 1/1 Size Grid for Oven – Technical Sheet

1. Definition and Features

The GN 1/1 grid (Gastro Norm 1/1) is a standardized accessory used in professional kitchens. It measures 530 x 325 mm, corresponding to the GN 1/1 format – an international standard designed to harmonize cooking, storage, and serving equipment.

Made of stainless steel or sometimes chrome, this grid is designed to withstand high temperatures (often up to 300°C), humidity, and frequent mechanical stress in professional use.

2. Usefulness

• Cooking support: The GN 1/1 grid is used in professional ovens to hold food directly or support GN containers (Gastro-Norm pans).

• Even baking: Its open design allows for optimal hot air circulation, ensuring even cooking.

• Versatility: Compatible with many types of ovens (combi, convection, steam), it is suitable for baking, roasting, grilling, or dehydrating various foods.

• Modularity: It can be placed on different levels inside the oven, depending on cooking needs and preparation size.

3. Cleaning and Maintenance

Proper maintenance ensures the grid’s durability and guarantees hygiene:

• Daily cleaning:

  • Let the grid cool before cleaning.

  • Use a non-abrasive sponge with warm soapy water or a food-safe degreaser.

  • Rinse thoroughly with clear water and dry with a clean cloth to prevent water spots.

• Intensive cleaning (weekly or as needed):

  • Soak the grid in a degreasing bath or soda solution (compatible with stainless steel) to loosen burnt grease.

  • Use a soft stainless-steel brush if needed.

  • Run it through a professional dishwasher if allowed by the manufacturer.

• Recommendations:

  • Never use chlorine-based or abrasive products which may damage the surface.

  • Regularly check welds and metal condition to prevent food contamination.
