Stainless GN Pans: A Complete Buying Guide

A commercial kitchen relies on precision, durability, and efficiency. Every piece of equipment plays a crucial role, but few are as fundamental as the Gastronorm (GN) pan. These standardized containers are the unsung heroes of professional food service, used for everything from cooking and chilling to storing and serving. When it comes to choosing the right material, stainless steel stands out as the industry favorite.

This guide will walk you through everything you need to know about stainless GN pans. We'll cover the different types of stainless steel available, explain the sizing system, and provide tips on how to choose the perfect pans for your kitchen's needs. By the end, you'll understand why these pans are an essential investment for any food service operation aiming for quality and consistency.

What Are Stainless GN Pans?

Gastronorm (GN) pans, often called hotel pans or steam table pans, are a system of standardized food containers used in the catering and food service industry. The "GN" standard was first introduced in Switzerland in the 1960s and later adopted across Europe and the world. This universal sizing ensures that pans from different manufacturers are interchangeable, fitting seamlessly into prep stations, combi ovens, chafing dishes, and refrigerators.

A stainless GN pan is simply a Gastronorm-sized pan made from stainless steel. This material is preferred for its exceptional durability, resistance to corrosion and heat, and non-reactive properties, which means it won't interfere with the flavor or color of food. These qualities make stainless steel the go-to choice for busy commercial kitchens that demand reliability and performance.

Understanding Stainless Steel Grades

Not all stainless steel is created equal. The material is an alloy of iron, chromium, and sometimes other elements like nickel and molybdenum. The specific composition determines the steel's properties, including its resistance to rust and its durability. In the context of GN pans, you'll most commonly encounter two grades: 201 and 304.

201 Stainless Steel

201 stainless steel is an austenitic alloy that substitutes some of its nickel content with manganese and nitrogen. This makes it a more cost-effective alternative to 304 stainless steel.

◆Pros: Lower cost makes it an attractive option for businesses on a tight budget. It offers good durability and is suitable for many general-purpose applications.

◆Cons: It has lower corrosion resistance compared to 304 grade. It is more susceptible to rust and pitting, especially when exposed to salty or acidic foods for extended periods.

304 Stainless Steel

Often referred to as "18/8" or "18/10" stainless steel (referring to its chromium and nickel content), 304 is the most common grade used in food equipment.

◆Pros: Superior corrosion resistance makes it ideal for direct contact with all types of food, including acidic ingredients like tomatoes or vinegar. It is highly durable, easy to clean, and maintains its appearance over time.

◆Cons: The higher nickel content makes it more expensive than 201 stainless steel.

Which Grade Should You Choose?
For most commercial kitchens, 304 stainless steel is the recommended choice for GN pans. Its enhanced durability and resistance to corrosion justify the higher initial investment, leading to a longer service life and better food safety. Pans made from 201 steel can be a viable option for dry storage or for businesses with limited budgets, but they require more careful handling to prevent rust.

The GN Pan Sizing System

The Gastronorm system is based on a "full-size" pan, the GN 1/1, which measures 530 x 325 mm. All other sizes are fractions of this base measurement, allowing for flexible and modular arrangements.

Here is a breakdown of the standard GN pan sizes:

GN Size	Dimensions (mm)	Common Uses
GN 2/1	650 x 530	Large batch cooking, roasting large cuts of meat
GN 1/1	530 x 325	Roasting, baking, serving main courses on a buffet
GN 2/3	354 x 325	Side dishes, smaller main courses, casseroles
GN 1/2	325 x 265	Popular for side dishes, salads, and holding sauces
GN 1/3	325 x 176	Condiments, toppings, small sides, salad bar items
GN 1/4	265 x 162	Small portions, garnishes, mise en place
GN 1/6	176 x 162	Spices, toppings, individual dessert components
GN 1/9	176 x 108	Smallest toppings, spices, garnishes

Understanding Pan Depth

In addition to their fractional length and width, GN pans also come in standardized depths. This adds another layer of versatility, allowing you to choose a pan with the right volume for your needs.

Common depths include:

◆20 mm (¾")

◆40 mm (1 ½")

◆65 mm (2 ½")

◆100 mm (4")

◆150 mm (6")

◆200 mm (8")

A shallow GN 1/1 pan (20mm) is perfect for cooking flatbreads or presenting cold cuts, while a deep GN 1/1 pan (200mm) is ideal for holding large batches of soup or chili in a serving line.

Key Features to Look For

When purchasing stainless GN pans, several features can enhance their functionality and longevity.

Anti-Jam Stacking Lugs

One of the most common frustrations in a busy kitchen is trying to separate pans that have become stuck together. Anti-jam stacking lugs are small, indented ridges around the corners of the pan. This design prevents a vacuum from forming when pans are stacked, allowing them to be separated easily. This feature saves time, reduces staff frustration, and prevents damage to the pans.

Reinforced Edges and Corners

The edges and corners of a GN pan are the areas most susceptible to dents and dings from daily use. Pans with reinforced, flattened rims are more resistant to bending and warping. This not only extends the life of the pan but also ensures it sits flat in steam tables and maintains a proper seal with lids.

Perforated vs. Solid Pans

While most GN pans are solid, you can also purchase perforated versions.

◆Solid Pans: These are the standard for most cooking, storing, and serving applications.

◆Perforated Pans: These pans have small holes in the bottom, allowing steam to circulate and liquids to drain away. They are excellent for steaming vegetables, draining excess fat from meats, or holding washed produce.

Make the Right Investment for Your Kitchen

Stainless GN pans are more than just containers; they are a core component of an efficient and organized kitchen. By understanding the differences in stainless steel grades, mastering the sizing system, and recognizing key design features, you can make an informed purchasing decision that will benefit your operation for years to come.

Choosing high-quality, 304-grade stainless steel pans with anti-jam features is a wise investment in durability and food safety. While the upfront cost may be higher, the long-term savings from reduced replacement needs and improved operational flow make them the superior choice for any serious food service professional. Equip your kitchen with the right tools, and you'll be well on your way to culinary success.
