Premium, Durable Cast Iron for Real-World Grilling

When you swap to Uniflasy cast iron grill grates, you invite a serious upgrade in heat retention and searing potential. These grates are built to withstand year-round grilling, delivering consistent performance across the entire cooking surface.

Built to Last with Thoughtful Compatibility

Constructed from solid cast iron, the grates resist chipping and warping, maintaining their shape while you experiment with temperatures and flavors. They’re designed to fit Weber Spirit 300 Series models (including E310 and S310) as well as Spirit II 300 series and related Genesis models like Silver B/C and Gold B/C (2002+), Genesis 1000–3500, and Genesis Platinum (2000–2010). They also cover Weber 900-series and even some SmokeFire pellet grills. Note: they are not compatible with Genesis Silver A.
