In the demanding environment of a commercial kitchen, hygiene, durability, and safety are non-negotiable. Choosing the right grade of stainless steel for your kitchen equipment isn’t just a matter of aesthetics or preference—it’s a decision that impacts longevity, food safety, and maintenance costs. At Grey Simmonds Ltd, we understand the critical role materials play in commercial kitchen performance. Here’s our guide to selecting the right grade of stainless steel for your operation.
Why Stainless Steel?
Stainless steel is the preferred material in commercial kitchens for good reason. It’s non-porous, corrosion-resistant, easy to clean, and strong enough to withstand daily wear and tear. However, not all stainless steel is created equal—different grades offer different properties.
Common Grades Used in Commercial Kitchens
Grade 304: The Industry Standard
Composition: Contains 18% chromium and 8% nickel
Benefits: Excellent corrosion resistance, easy to clean, and highly durable
Ideal for: Worktops, sinks, splashbacks, shelving, and general kitchen fixtures
Grade 304 is the most widely used stainless steel in commercial kitchens. It resists oxidising acids and is highly resistant to rust, making it ideal for environments where cleanliness and moisture resistance are key.
Grade 316: For Harsh Environments
Composition: Similar to 304 but with added molybdenum (around 2-3%)
Benefits: Superior corrosion resistance, especially against chlorides and saline environments
Ideal for: Coastal kitchens, seafood preparation areas, and applications involving acidic foods or chemicals
If your kitchen is subject to harsh cleaning agents or is located in a coastal area, Grade 316 may be a better long-term investment due to its enhanced corrosion resistance.
Grade 430: The Budget-Friendly Option
Composition: 17% chromium and no nickel
Benefits: Magnetic, lower cost, and decent corrosion resistance for dry environments
Ideal for: Decorative panels, equipment fronts, and low-moisture areas
Grade 430 is less corrosion-resistant than 304 and 316, but it’s a cost-effective choice for areas that don’t come into direct contact with food or moisture.
Factors to Consider When Choosing a Grade
Exposure to Moisture & Chemicals: The more exposure to water, salts, and cleaning agents, the higher the grade should be.
Food Type and Preparation: Acidic foods (like tomatoes and citrus) can be more corrosive; a higher grade may be needed.
Budget Constraints: While premium grades cost more upfront, they can save money in maintenance and replacement costs over time.
Compliance & Hygiene: Ensure your chosen material complies with local food safety regulations.
