Cast iron grates are a great way to up your grilling level. Cast iron has a much higher thermal capacity than the standard grill grates. When that heat is unleashed onto a juicy porterhouse, the result is an amazing set of dark mahogany grill marks that only cast iron grates can offer.
The Weber charcoal grill is the one to have and everyone knows it. Even though Weber doesn’t offer a full cast iron grate of her own, there are several fantastic cast iron grate options available for all sizes of the Weber charcoal grill.
Except for the Ranch, there are no cast iron options for that. Can you imagine how heavy a 37″ cast iron grate would be? Oh my damn.
