Aluminum grills are crafted from blackened cast aluminum, and stainless steel models have a bright, shiny metallic look. When it comes to appearance, you can choose the style that best suits your taste and decor. Either way, your new grill will look great and cook your food well.
Stainless steel grills cost more because stainless steel is a more difficult material to work with. It has to be heat treated more intensely and is harder to shape when it starts to cool. Stainless steel is also more resistant to impact damage because it is harder, but aluminum is easier to repair.
Both stainless steel and aluminum models come in a variety of different sizes with a variety of mounting options. You can install a portable liquid propane grill on a wheeled cart, a permanently mounted grill on a pedestal, or an outdoor grilling countertop.
While both aluminum and stainless steel grill models are highly corrosion-resistant and built to last, it's important to take good care of your grill to ensure it continues to perform as advertised for years to come. You should wipe down your grill thoroughly before and after each grilling season and after taking it out of storage to make sure you haven't pinched or scratched any fittings and hoses.
