1/3 Gastronorm Pans are one of the internationally standardized food service containers, primarily used for food storage, heating, insulation, and display. Manufactured using a one-piece stainless steel stretch forming process, these pans feature a smooth, flat surface and uniform thickness, making them suitable for various commercial kitchens, food delivery, and buffet equipment. The 1/3 size represents that it occupies one-third of the space of a standard GN 1/1 plate, measuring 325 × 176 mm, with depths ranging from 20 mm to 200 mm and volumes ranging from 5.51 to 18.1 liters. Whether used for refrigeration, steaming, or heating/insulation, this series maintains high stability and airtightness, providing standardized operations and efficient storage for the food service industry.

1/3 Gastronorm Pans Parameters:

1/3 Gastronorm Pans Features:

• High Strength: The 1/3 Gastronorm Pans are made of food-grade SS304 stainless steel, boasting a tensile strength of 520 MPa and a yield strength of approximately 210 MPa, providing excellent impact and deformation resistance. The 0.6–0.7 mm thickness ensures long-term structural stability in high-temperature steam environments, having been tested to withstand continuous 120°C steam heating for 8 hours without warping. Reinforced edge technology enhances overall deformation resistance by approximately 30%, ensuring durability during multi-layer stacking and frequent handling.

  
  

• High Precision: Each pan is manufactured using automated stamping and CNC trimming processes, with dimensional errors controlled within ±0.5 mm. The corner radius is uniformly R10, allowing for precise embedding in standard GN (Gastronorm Injection) equipment. The depth of each model strictly conforms to GN standards; for example, the 1/3 × 100 mm deep model has an actual volume of 9.69 liters, effectively controlling portion sizes. Standardized production ensures interchangeability between different batches, enhancing the compatibility of commercial kitchen equipment.

  
  

• High Cleanliness: The inner surface undergoes electrolytic polishing, achieving a surface roughness Ra≤0.4 μm, minimizing food particle residue and improving cleaning efficiency by 40%. Materials meet EU LFGB and US FDA food contact standards, allowing direct contact with raw and cooked foods. The polished layer effectively reduces oil adhesion, maintaining over 90% gloss retention after 500 cleaning cycles, ensuring food hygiene and safety.

  
  

• Corrosion Resistance: The product shows no signs of rust after 96 hours of salt spray testing, suitable for refrigerated, steam, and high-humidity environments. The surface passivation film is approximately 3–5 nm thick, preventing chloride ion corrosion. The weld areas utilize a closed welding and re-passivation process, improving overall corrosion resistance by approximately 25%. Long-term use in common catering disinfectants (containing 250 ppm chlorine) shows no discoloration or spots.

  
  

• Easy Stacking: All models feature a stackable structure with a stacking gap of 7 mm, helping to save 35% of storage space. The flanged design ensures stability and airflow during stacking, preventing vacuum adhesion. According to laboratory tests, after stacking 20 layers consecutively, there is no significant deformation at the edges, making it suitable for large-volume warehousing or transportation.

1/3 Gastronorm Pans Application:

• Buffet Restaurants: 1/3 Gastronorm Pans are used for food display in buffet warming stations, cold food stations, or steaming stations. The standard 1/3 size can be flexibly combined with other GN containers to achieve diverse food pairings. When used with heating equipment, it can maintain food temperature within the 60–80°C range, ensuring consistent taste.

  
  

• Commercial Kitchens: Suitable for partitioned storage, preparation, and refrigeration of ingredients in kitchens. The 325×176 mm size facilitates placement on refrigerated display rails. Different depth models can meet the classification and management of liquids, solids, and semi-finished products. The smooth surface allows for daily high-temperature washing and sterilization, complying with the HACCP food safety management system.

  
  

• Food Delivery: 1/3 Gastronorm Pans are suitable for central kitchens, restaurant chains, and centralized delivery centers. The 0.7 mm thickness helps maintain shape stability during transportation vibrations, preventing contents from spilling. Can be used with lids and silicone sealing rings to improve freshness during transport.

  
  

• Medical Meal Preparation: Used for packaging hot and nutritious meals in hospital and nursing home catering systems. Made of 304 stainless steel, it can withstand daily high-temperature steam sterilization, avoiding the aging and odor problems associated with plastic containers. Standard volume control allows for precise portion control, meeting nutritional management requirements.

1/3 Gastronorm Pans FAQs:

1. What are the standard dimensions of this 1/3 GN plate?

The standard size is 325 × 176 mm. Depths are available in 20, 40, 65, 100, 150, and 200 mm, corresponding to a volume range of 5.51–18.1 liters. It fully complies with EN631-1 European standard GN specifications.

2. Is the material suitable for long-term food contact?

Yes, it is made of food-grade SS304 stainless steel, certified by LFGB and FDA food safety standards. It can directly contact raw and cooked foods without releasing harmful substances.

3. Can it be used in dishwashers and steamers?

Yes. The plate is temperature resistant from -40°C to 300°C and can be repeatedly used in dishwashers and steamers without deformation.

4. Can it be stacked and used with a lid?

Yes. The product features a standardized, stackable structure, compatible with 1/3-size stainless steel lids, lids with handles, or silicone sealing lids for convenient storage and insulation.

5. What are the differences in thickness, and what scenarios are they suitable for?

0.6 mm thickness is suitable for general catering and buffet use; 0.7 mm thickness is suitable for frequently moved or industrial kitchen environments, offering higher strength and better pressure resistance.
