What is the best material for grill grates?

The best material for grill grates depends on your grilling goals. Stainless steel is great for low maintenance and even heat distribution, while cast iron excels in heat retention and searing. For most users, a combination of both, like stainless steel with cast iron grates, provides versatility and performance.

Do stainless steel grates rust?

Stainless steel grill grates are generally resistant to rust and corrosion due to the alloy’s composition, which includes chromium. Chromium forms a protective layer on the surface of the stainless steel, known as chromium oxide, which helps prevent rusting and staining. However, stainless steel is not entirely immune to rust under certain conditions.

Here are some factors that can contribute to rusting on stainless steel grates:

  1. Poor-Quality Stainless Steel: Lower-quality stainless steel or grates with a lower chromium content may be more susceptible to rust. High-quality stainless steel, such as 304 or 316 stainless steel, is more resistant to corrosion.
  2. Exposure to Chlorides: Stainless steel grates can still rust if exposed to high levels of chlorides, such as from salt or pool chemicals. For this reason, it’s important to rinse off salt residue, especially in coastal or beachfront areas.
  3. High Heat and Grease Buildup: Extremely high temperatures and a buildup of grease or food residue on the grates can cause the protective chromium oxide layer to break down, making the stainless steel more susceptible to rust.
  4. Neglected Maintenance: Inadequate cleaning and maintenance can lead to the accumulation of corrosive substances and contaminants on the grates, potentially promoting rust formation.

How to prevent rust on stainless steel grill grates

  • Clean the grates regularly, ideally after each use, to remove grease and food particles.
  • Avoid using abrasive cleaning tools or harsh chemicals that can damage the protective layer.
  • If you live in a coastal area or use your grill near a pool, rinse the grates thoroughly after each use to remove any salt residue.
  • Periodically inspect the grates for signs of rust or corrosion and address any issues promptly.
  • Consider covering your grill when it’s not in use to protect it from the elements.

In most cases, stainless steel grill grates are a reliable choice for outdoor grilling due to their resistance to rust. Proper maintenance and care will help ensure they remain in excellent condition and continue to provide you with great grilling experiences.


The choice between stainless steel and cast iron grill grates ultimately depends on your grilling style, preferences, and maintenance habits. Stainless steel grates are durable, low-maintenance, and versatile, making them a practical choice for many grillers.

Cast iron grates, on the other hand, excel at flavor enhancement, heat retention, and even heat distribution, making them ideal for searing and achieving that perfect crust. Nonetheless, we recommend stainless steel due to its many benefits.
