The biggest reason to consider them is simple: the cast iron core with a polished porcelain coating sears better and holds heat far longer than thin stainless replacements, delivering more consistent cooking and prominent sear marks. They arrive as a set of three pieces sized to match Genesis II\/LX 400 Series layouts and feel noticeably more substantial than many third-party options.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits Genesis II\/LX 400 Series (2017 and newer) including E\/S-410, E\/S-415, E\/S-435 and LX E\/S-440, replacing several listed Weber part numbers for straightforward swap in many grills.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize and package:\u003c\/strong\u003e Each grate measures 18.75 in x 11.12 in and ships as three pieces for a combined 18.75 in x 33.36 in cooking surface that matches the two-burner layout.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterials:\u003c\/strong\u003e Cast iron core with a polished porcelain coating provides a nonstick-like finish at high heat while preserving the superior heat retention of cast iron.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat retention:\u003c\/strong\u003e The cast iron under the porcelain heats hotter and cooks more evenly, producing the strong sear marks that many users expect from a heavy iron grate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Heavier build at 15.83 lb and thicker rods (11.8 mm) improves stability and longevity compared with lighter aftermarket grates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance:\u003c\/strong\u003e The porcelain surface cleans with a regular brush and benefits from seasoning with oil after cleaning to prevent rust and preserve the finish.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis set is aimed at homeowners and grilling enthusiasts who want improved searing and heat retention over thinner replacement grates, and who are comfortable swapping parts on Genesis II\/LX 400 Series models (2017+).
