These Hongso SUS304 replacement grill grates are a pair of food‑grade 304 stainless steel cooking grids sized to fit Weber Genesis II 300 Series (2017+) models, providing even heat, durable searing surfaces, and corrosion resistance.

Built from heavy‑gauge SUS304 stainless steel, the grates are designed to hold heat reliably, resist warping, and produce clear sear marks while remaining food‑safe and easy to maintain. They are a direct replacement for Weber part numbers 66095 and 66802 and fit a range of Genesis II and LX 300 models, plus several compatible KitchenAid and other grill housings.

How do these SUS304 grates affect cooking performance?

SUS304 stainless provides consistent heat conduction and strong surface durability, so foods sear evenly and juices caramelize without excessive sticking. The solid rods retain heat to help maintain stable cooking temperatures when you add or remove food.

• Thick stainless rods improve heat retention for consistent searing across the surface.
• Corrosion resistance reduces rusting and pitting compared with coated grates.
• Stainless surface is easy to clean after cooking — good for repeated use.
• Designed to produce pronounced grill marks for professional-looking results.

How should I care for these stainless steel grates?

Routine cleaning and proper storage extend the life of stainless grates. Use basic grilling maintenance to keep surfaces performing and looking good.

• Preheat and brush grates after cooking to remove residue while warm.
• For deeper cleaning, soak and scrub with a non‑abrasive pad and mild detergent.
• Rinse and dry thoroughly to prevent water spots; avoid harsh chemical bleach.
• Inspect tabs and mounting points before reinstalling to ensure secure fit.
