It’s crucial to choose the correct cooking grates for your Weber barbecue. Many grates are made of porcelain-coated steel or cast iron. Regular steel grates are less expensive, but they will not withstand the heat or misuse. If not correctly cared for, their edges can be chipped and nicked, and they can rust. An actual stainless steel grate is smoother and less likely to cling, as well as rust.
