Aluminum and Stainless Steel Grills: Which One is Right for You?
6 minute read | Grills

You’ve got a quarter of a ton of grass-fed Kobe steak in the freezer, and there's just one thing you need to decide—should you use an aluminum or stainless steel natural gas grill? The answer really comes down to your personal preference. Both materials offer great performance, durability, and style. But which one suits your needs best? Let’s dive in.
If you're researching the best gas grills on the market, you've probably noticed that aluminum and stainless steel are two of the top choices. They both look good, fit a variety of styles, and are resistant to rust. Plus, they come with many appealing features. Before we compare them, let’s first understand what makes each unique.
What Are Aluminum and Stainless Steel Gas Grills?
When we say a grill is made of cast aluminum or stainless steel, we’re usually referring to the main body, like the lid and cooking chamber. However, it's important to note that most grills have essential components made from stainless steel, such as the grates and burners. So even if a grill is labeled as aluminum, it still has stainless steel parts.
The key differences between these two types of grills lie in their appearance, weight, and cost. Aluminum grills often have a blackened, rugged look, while stainless steel models shine with a polished, modern finish. Choosing between them depends on your personal taste and how your outdoor space looks.
If you're planning to install a built-in grill, either material will work well. Both are durable and can handle the elements. If you can't store your grill during the winter, a weatherproof cover is a must. Proper care ensures longevity, no matter which material you choose.
Stainless steel grills tend to be more expensive because the material is harder to shape and requires more heat treatment. They're also more resistant to impact, but aluminum is easier to repair. In terms of corrosion resistance, stainless steel generally lasts longer in moist conditions. Still, with proper maintenance, both will serve you well for years.
Common Features of Aluminum and Stainless Steel Grills
As mentioned, both types of grills have stainless steel components like grates and burners. This is not only for safety—corroded metal can release harmful particles when heated—but also for aesthetics. These internal parts look sharp and perform reliably.
Both aluminum and stainless steel grills come in various sizes and mounting options. Whether you want a portable LP grill on wheels, a built-in model on a pedestal, or a countertop setup, there's something for every lifestyle.
They also share many features, such as 60-minute gas shut-off timers, storage drawers, warming racks, and match-free lighting systems. The timer is especially useful for public spaces and adds a layer of safety. Other helpful additions include theft-resistant knobs and laser-etched instruction plates that never fade.
Before choosing, take time to measure your space and consider the size and mounting options that fit your needs. A well-chosen grill can enhance your outdoor cooking experience for years.
Maintenance Tips for Your Grill
Even though both aluminum and stainless steel grills are highly durable, regular maintenance is key to keeping them in top condition. Clean your grill thoroughly before and after each season, and inspect connections, burners, and other parts for damage or clogs. Using a weatherproof cover and storing your grill properly during off-seasons can help extend its life.
