GN pans, also known as Gastronorm pans or containers, are standardized containers used in the food service industry for storing, cooking, and serving food. They are commonly made of stainless steel due to its durability, corrosion resistance, and ease of cleaning. GN pans come in various sizes and depths, allowing for efficient storage and organization in professional kitchens.

The "2/1 Size" refers to the standard size designation for GN pans. The 2/1 size is one of the larger sizes available and is designed to fit into specific food service equipment, such as hot food holding cabinets or steam tables. The dimensions for a GN 2/1 pan are approximately 530mm x 650mm (length x width).

The depth options are (20mm, 65mm, 100mm, and 150mm) which indicate the height or depth of the GN pan. The depth of the pan determines the volume of food it can hold.
