GGC 19.5" Cast Iron Grill Grates for Weber Genesis 300 Series — 2‑Piece Set, Heavy‑Duty Heat Retention

These are heavy-duty 19.5" cast iron cooking grates from GGC made to replace the factory 7524/7528 grates in Weber Genesis 300-series grills (E‑300, S‑300, EP‑300 models built 2007–2016).

If your Weber Genesis E‑310, E‑320, E‑330, S‑310, S‑320, S‑330, EP‑310, EP‑320 or EP‑330 has worn or warped grates, this pair of GGC replacement cast‑iron grids restores even heating, strong sear marks and long-term durability. Each grate measures 19.5" long by 12.9" wide; the set contains two pieces to cover the full cooking area. These are aftermarket replacements designed for specific 300‑series models and are not compatible with Genesis II or Genesis II LX 300 models, so measure your originals before ordering.

Will these GGC grates fit my Weber Genesis 300 series grill?

They are intended for the classic Weber Genesis 300 family produced between 2007 and 2016, including E‑310/E‑320/E‑330 and S/EP‑310/320/330 variations. Compatibility depends on the original grate dimensions and mounting points.

• Designed for Weber 7524/7528 replacement.
• Each grate: 19.5" L x 12.9" W; pack of 2 covers 19.5" x 25.8" total.
• Compatible models: E‑310/E‑320/E‑330 (2007–2016), S/EP‑310/320/330 (2011–2016).
• Not compatible with Genesis II or Genesis II LX 300 series grills.

How does the cast iron construction affect cooking?

Cast iron retains and distributes heat very well, producing steady surface temperature for searing and caramelization. That means more pronounced grill marks, less temperature drop when you add food, and even cooking across the grate.

• High heat retention for consistent searing and browning.
• Creates defined grill marks for professional-looking results.
• Durable material resists bending under normal use.
• Heats uniformly to reduce hot/cold spots on the cooking surface.

What practical details should I know before buying?

Check your grill’s original grate measurements and mounting style to confirm fit. These are sold as an aftermarket 2‑piece set; routine maintenance like seasoning and cleaning will extend their life. Expect a slightly different finish from OEM grates but the same functional benefits.

• Measure your existing grates and compare to 19.5" x 12.9" per piece.
• Sold as a two-piece set—sufficient to replace the full cooking grid area.
• Requires seasoning and regular cleaning to prevent rust and improve nonstick performance.
• Check mounting tabs and grate supports on your particular grill model before purchase.

How do I care for and maintain these cast iron grates?

Cast iron benefits from simple, regular upkeep: keep them seasoned, clean food residue after each use, and dry thoroughly to prevent oxidation. A thin coat of oil after cleaning protects the surface and improves future nonstick performance.

• After cooking, brush off debris and wipe with a paper towel while warm.
• Apply a light coat of high‑smoke‑point oil and heat briefly to season.
• Avoid extended exposure to moisture; store indoors or covered when not in use.
• Use a stiff nylon or brass brush—avoid harsh detergents that strip seasoning.

Who is this for? Grill owners with older Weber Genesis 300‑series units who want a durable, high‑heat cooking surface to restore performance and sear quality. If you own a compatible E‑300, S‑300 or EP‑300 model from the specified years and prefer cast‑iron cooking benefits—better heat retention and stronger sear marks—this GGC two‑piece set offers an affordable aftermarket option. If your grill is a Genesis II, Genesis II LX, or a different size, verify fit or seek model‑specific parts to ensure proper installation.
