The matte enamel finish helps protect the iron while avoiding the chipping issues common with some porcelain coatings when they’re nicked or stressed.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHeavy solid rods increase heat retention and evenness.\u003c\/li\u003e\n  \u003cli\u003eMatte enamel resists flaking better than thin porcelain coatings.\u003c\/li\u003e\n  \u003cli\u003eThicker construction reduces warping under high heat.\u003c\/li\u003e\n  \u003cli\u003eRequires simple oiling to maintain the cooking surface and prevent rust.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat maintenance and care do these replacement grates need?\u003c\/h3\u003e\n\u003cp\u003eCast iron benefits from routine seasoning: lightly oil the grates before and after each use and avoid metal scrubbers that strip the finish. Clean off food residue with a nylon brush while the grate is warm, then reapply a thin coat of cooking oil to keep the enamel-protected surface performing longer.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBrush with non-metallic tools; avoid steel wool that damages the finish.\u003c\/li\u003e\n  \u003cli\u003eLightly oil before first use and after each cleaning to preserve seasoning.\u003c\/li\u003e\n  \u003cli\u003eStore in a dry place if grill will be unused for extended periods.\u003c\/li\u003e\n  \u003cli\u003eFollow standard gas-grill safety and cleaning routines.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhich benefits should I expect after swapping to Charbrofire grates?\u003c\/h3\u003e\n\u003cp\u003eExpect faster searing, clearer grill marks, and a more even cooking surface across the two-piece set. Because these grates are heavier and use larger-diameter rods, they retain heat better during lid openings and hold steady temperature for thicker cuts.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eImproved sear and caramelization for steaks and chops.\u003c\/li\u003e\n  \u003cli\u003eMore consistent heat across the cooking area.\u003c\/li\u003e\n  \u003cli\u003eDurable build reduces chance of cracking or warping with normal use.\u003c\/li\u003e\n  \u003cli\u003eDirect-fit replacement minimizes installation time.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Grill owners with a Weber Genesis II 300-series (2017 and newer) who want a heavy-duty, long-lasting replacement grate set that improves sear, heat retention, and cooking consistency. If your grill panel reads \"GENESIS II\" and you want an upgrade from thinner or chipped porcelain grates, these Charbrofire matte-enamel cast iron pieces are a practical, compatible option. If you’re unsure whether your model qualifies, check the grill panel for the \"II\" designation or contact the seller with your grill model year and serial details.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these grates fit Weber Genesis II 300 series grills?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — they fit Genesis II 300 and LX 300 models (2017+), matching several Weber part numbers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How should I clean and season the cast iron grates?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Brush with non-metal tools when warm, oil lightly before and after use to maintain the finish.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Charbrofire","offers":[{"title":"Default Title","offer_id":56839062946132,"sku":"B09TS1G34T","price":113.05,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/charbrofire-front-packaging-grates_49799571-22c8-4b55-982c-2aed00738133.jpg?v=1787064892","url":"https:\/\/gardenluxe.co.uk\/products\/charbrofire-cast-iron-replacement-grates-for-weber-genesis-ii-300-series-matte-enamel-pair-2017","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
