Perforated GN pans are similar to regular GN pans but feature small holes or perforations on the bottom or sides of the pan. These perforations allow for the drainage of liquids and help to keep the food dry or separate from excess liquids.

GN pans, including perforated ones, are commonly used in the food service industry for storing, cooking, and serving food. They are made of stainless steel, which provides durability, corrosion resistance, and ease of cleaning. GN pans come in various sizes, with 1/1 size being a standard size that fits into food service equipment such as hot food holding cabinets or steam tables.
