These Stok brand cast iron grates are made for a different grill, but fit the 22″ Weber perfectly. The grates are porcelain coated cast iron, so you don’t need to worry about seasoning and rust.
The center section of the grate is removable and big enough for a charcoal chimney to sit. The top surface of the Stok cast iron grates is rounded. The grill marks from these cast iron grates aren’t all that great, but they definitely have the cast iron thermal performance.
