Made from solid cast iron and finished for easier seasoning, this two-piece set restores high-temperature performance and improves sear marks compared with thinner porcelain-coated rods. The grate geometry has wider flat slats and narrower gaps to reduce flare-ups, keep smaller foods from falling through, and improve heat distribution across your cooking surface.\u003c\/p\u003e\n\n\u003ch3\u003eWhich grills and model numbers will these grates fit?\u003c\/h3\u003e\n\u003cp\u003eThese QuliMetal grates are designed for the original Weber Genesis 300-era chassis and several model variations produced between 2007 and 2016.

Proper seasoning and routine oiling create a naturally anti-stick layer for cleaner releases and easier cleanup over time.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThicker mass holds higher temperatures for consistent searing\u003c\/li\u003e\n  \u003cli\u003eFlat wide slat design increases contact area for bolder grill marks\u003c\/li\u003e\n  \u003cli\u003eNarrower gaps help prevent small foods from slipping through\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat are the size, weight, and package details?\u003c\/h3\u003e\n\u003cp\u003eEach grate measures 19.5 x 12.9 inches; the set contains two grates that combine to 19.5 x 25.8 inches of cooking width. These replacement grates are notably heavier than many stock options, which contributes to their heat retention but requires sturdier handling when installing or cleaning.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIndividual grate: 19.5 x 12.9 inches\u003c\/li\u003e\n  \u003cli\u003eSet dimensions: 19.5 x 25.8 inches total cooking area\u003c\/li\u003e\n  \u003cli\u003eTotal set weight ~15.17 pounds (heavier than many OEM rods)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow should I care for and maintain these cast iron grates?\u003c\/h3\u003e\n\u003cp\u003eCast iron lasts longest when kept seasoned and cleaned gently. After each use, remove food debris, lightly oil the cooking surface while warm, and store in a dry place to protect against rust. Avoid harsh detergents and long soaking; re-season if the surface looks dull or sticky.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eClean with a grill brush or scraper while warm\u003c\/li\u003e\n  \u003cli\u003eApply a thin coat of high-smoke-point oil after cleaning\u003c\/li\u003e\n  \u003cli\u003eRe-season periodically by heating with oil to restore non-stick properties\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Home grillers who own an older Weber Genesis 300-series or compatible Pit Boss and want to upgrade to robust cast iron grates for better searing, even heat, and a longer-lasting cooking surface. These grates are ideal if you frequently cook steaks, burgers, or other foods that benefit from a high-heat sear and want a replacement that resists chipping and rust better than thin porcelain rods.\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: Will these grates fit my Weber Genesis II 300?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. These QuliMetal grates do not fit Weber Genesis II 300 or Genesis II LX 300 series models.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How should I season and maintain these cast iron grates?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Clean after use, heat the grates, then apply a thin coat of high-smoke-point oil; re-season when surface looks dull.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"QuliMetal","offers":[{"title":"Default Title","offer_id":56835452862804,"sku":"B07MMMC83Q","price":116.82,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/qulimetal-front-packaging-view_fe410b76-ac14-46de-9034-6f814cd3e5c7.jpg?v=1787056726","url":"https:\/\/gardenluxe.co.uk\/products\/qulimetal-19-5-cast-iron-grill-grates-for-weber-genesis-300-series-two-piece-set-heavy-duty-searing-heat-retention","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
