Why use stainless steel for grills? Grills are mostly left outdoors with the elements and stainless steel resists weather quite well. Other grills are more likely to rust and need replacing sooner where Solaire grills will last quite a long time. It also helps that it's a nice shiny material that looks good. It's also pretty durable and will resist most damage that can happen to it barring extreme circumstances. The downside to stainless steel is that if neglected, it will appear dirtier than it is, but the upside to that is it's not difficult to clean or maintain. Overall it has less problems and more benefits than other materials and allows for a longer lifespan for Solaire grills.
