Convert your Weber grill into a griddle with the carbon-steel Rust-Resistant Griddle Insert. This cooktop is transformed under extreme heat and pressure that case hardens and bonds the surface, reducing the ability for moisture to collect and rust to form. Then it’s pre-seasoned with food-safe oils that condition the metal for an extra boost of rust resistance and a natural, easy- release cooking surface that makes it ready to use right out of the box. No use of coatings means it’s safe for metal tools. Simply remove your existing grates, place the griddle into the grill and enjoy making smashed burgers, bacon, eggs, fajitas, and stir-fries.
