적절한 것을 선택하기 GN pan is a key decision that is often underestimated in hotel buffets and commercial foodservice systems. It connects the entire process—from food preparation and cooking to refrigeration, heat retention, and serving. Selecting the wrong size or depth can lead to heat loss, cross-contamination of flavors, operational inconvenience, and safety hazards, which directly drive up costs and diminish the guest experience.
As a buffet equipment & stainless steel food tray manufacturer with twenty years of experience, 빌리언 데이 talks to hotel procurement teams around the world every single day about exactly these challenges. In this piece, we break it down across four areas—the GN standard system, materials and workmanship, a real case study, and common pitfalls—to help you make purchasing decisions with a lot more confidence.
Understanding the GN Standard: The Foundation of Efficient Operations
The Gastronorm standard originated in Europe and has become the universal language of commercial kitchens worldwide. Its core lies in modular compatibility—different-sized containers can be flexibly combined within the same framework to fit equipment such as refrigerated cabinets, steam ovens, holding counters, and transport carts.
GN 1/1 is the standard full-size tray (530 mm × 325 mm), with all other sizes derived from this as fractions. In hotel buffets, GN 1/1 is suitable for large quantities of main courses, while GN 1/2 facilitates diverse serving station layouts.
Depth is equally critical. Common depths range from 20 mm to 200 mm. Shallow trays (40–65 mm) are suitable for cold dishes, salads, and pastries; deep trays (100 mm and above) are ideal for main courses with gravies, stews, and soups, as they prevent spills and retain heat. Many customers focus only on length and width while neglecting depth, leading to insufficient soup capacity or collapsed serving stations—issues that can be avoided in advance.
Practical Case Study: Improving Efficiency at a Pasta Station
Last year, a hotel chain encountered a common problem while renovating its buffet line: the pasta station used 150mm-deep GN 1/1 trays to hold two types of sauce. Each tray weighed over 12 kg, and frequent replacement during peak hours resulted in significant physical strain, frequent spills and scalds, and slowed service.
After an on-site assessment, Billion Day proposed an adjustment based on the existing GN framework: replacing a single deep tray with two 65mm-deep GN 1/2 shallow trays, each holding a different sauce.
The results are as follows:
- Safer operation: The weight per tray was reduced to 4–5 kilograms, allowing for stable one-handed handling and cutting changeover time by nearly 60%;
- More efficient workflow: By alternating between the two trays and preheating the next batch of sauce in advance, seamless service was achieved, preventing supply gaps or overheating;
- More visually appealing presentation: Displaying the two trays side by side creates a more harmonious look with the overall layout of the serving counter.
This entire adjustment was made without modifying any equipment, relying entirely on GN standard compatibility. The retrofit cost was extremely low, and efficiency improved significantly—this is precisely the value of combining GN pan selection with the expertise of a professional buffet equipment and stainless steel food tray manufacturer: it’s not just about selling products, but about helping customers find the optimal solution within their existing framework.
Three Core Criteria for Purchasing High-Quality GN Pans
Regardless of how suppliers market their products, the key to assessing the quality of GN pans lies in the following three points:
Material and Thickness
304 stainless steel (18/8 food-grade) is the mainstream choice for commercial catering equipment, offering corrosion resistance, high-temperature resistance, and ease of cleaning [2]. A thickness of at least 24 gauge (approximately 0.6 mm) is recommended; pans that are too thin are prone to warping during temperature fluctuations, which affects contact with heated serving counters and heat transfer efficiency. All Billion Day GN pans are made of full-thickness 304 stainless steel and undergo multiple polishing processes, resulting in a smooth, burr-free surface that is easy to clean and inhibits bacterial growth.

Edge Construction
Rolled edges or reinforcing ribs are key indicators of manufacturing quality. They enhance strength, prevent warping, and ensure the pan fits securely within the warming table frame. Low-cost products often use right-angle folded edges, which are prone to cracking with long-term use; this is a key factor to scrutinize during bulk purchases.

Surface Finish and Ease of Cleaning
Commercial kitchens require frequent cleaning, and surface finish directly affects cleaning efficiency. A high-quality buffet equipment and stainless steel food tray manufacturer’s investment in polishing processes determines the product’s long-term appearance and hygiene standards. Billion Day utilizes automated polishing production lines; its mirror-like finish prevents grease from adhering, significantly reducing the amount of cleaning agents needed and the time required for manual wiping [1].

4 Common Questions About Purchasing GN Pans
Q1: Are GN pan sizes universal worldwide?
A: Yes. Gastronorm is an international standard, so as long as the GN specification (e.g., GN 1/1) is indicated, the pans are compatible across brands [2].
Q2: Can different-sized trays be mixed within the same GN 1/1 rack?
A: Yes. A single GN 1/1 compartment can hold 2 GN 1/2 trays, 3 GN 1/3 trays, or 1 GN 1/2 tray plus 2 GN 1/4 trays[2], allowing for flexible combinations of various dishes without the need for additional equipment.
Q3: How do I choose the depth?
A: Choose based on the dish: Use 40–65 mm shallow trays for cold dishes and salads; 100–150 mm for main courses with gravy; and 150–200 mm for soups. If unsure, choose the 65–100 mm universal size.
Q4: Why is it better to work with a manufacturer than a distributor?
A: You have better control over quality, guaranteed delivery times, and greater flexibility for customization. Take Billion Day as an example: as a source manufacturer of buffet equipment and stainless steel food trays, we maintain full in-house control over the entire production process. Customization requests—such as logo embossing and minor size adjustments—are handled directly on the production line, ensuring quick response times and high tolerance for errors[1].
Conclusion: Choose a Professional Manufacturer for a Hassle-Free Procurement Experience
Procuring GN pans involves multiple considerations, including standard compliance, material selection, process evaluation, and suitability for specific scenarios. A professional manufacturer of buffet equipment and stainless steel food trays not only provides products that meet international standards but also leverages industry expertise to help customers avoid selection pitfalls and optimize operational workflows.
