Hongso Cast-Iron Grill Grates for Weber Genesis II 600 Series E-610/S-610 LX 640 - 3-Piece Heavy-Duty 18 7/8" x 40 5/16"

If your Genesis II 600-series grill needs new cooking grates, this Hongso set offers heavy-duty cast iron construction sized to match the original Weber 66096/66803 layout. The set includes three pieces that together measure 18 7/8" x 40 5/16" total and each piece includes the two stick-out tabs, making them a drop-in alternative for 2017 and newer Genesis II E-610, S-610 and LX 640 models. Built to retain heat and produce strong sear marks, these grates are SGS-tested for safety and non-toxicity.

Will these grates fit my Weber Genesis II E-610 or S-610 grill?

Yes — these Hongso grates are designed to be compatible with Weber Genesis II 600 series E & S 610 and Genesis II LX 640 (E-640/S-640) models from 2017 and newer. They mirror the original three-piece format and include the tabs needed for proper seating.

How do these cast-iron grates affect cooking results?

Cast iron is prized for its ability to absorb and hold heat, which helps create consistent temperatures across the cooking surface and bold sear marks on meat and vegetables. These Hongso grates will raise the grate surface temperature quickly and keep it stable under food loads, improving grilling performance compared with thin or warped factory grates.

• Heavy-duty cast iron for strong heat retention and even cooking
• Produces prominent sear marks for caramelized flavor
• Reduces hot and cold spots for more predictable results

What material and safety standards do these replacement grates meet?

The grates are cast from heavy-duty iron and have been tested by SGS to confirm they meet applicable safety and non-toxic standards for cookware surfaces. Proper seasoning and cookware care will protect the cast surface and extend working life.

• Material: durable cast iron designed for high-heat grilling
• SGS-tested to meet or exceed relevant safety criteria
• Recommended: season before first use and maintain with regular cleaning

How do I know these are the right replacement parts and how should I install them?

Before ordering, measure your current grates and confirm the dimensions and tab placement match the Hongso set. Installation is straightforward: remove old grates, place each Hongso piece onto the cooking grate supports so the tabs engage the same slots, and verify stable seating across all three pieces.

• Measure original grates to confirm compatibility before purchase
• Simple drop-in replacement using existing grate supports
• Keep older or warped grates as templates to compare tab locations

Who this set is for: Grill owners with a 2017-or-newer Weber Genesis II 600 series E-610/S-610 or Genesis II LX 640 who want to restore or upgrade searing performance. This Hongso three-piece cast iron set suits backyard cooks who value durable materials, improved heat retention, and bold grill marks. If you have a pre-2016 Genesis 300-series model, measure carefully because this set is not compatible with those earlier designs.
