BBQration 18 3/16" Matte Cast Iron Cooking Grate — Fits Big Green Egg Large, Heavy-Duty Heat Retention

BBQration’s 18 3/16" matte cast iron cooking grate is a heavy-duty replacement grate sized to fit Big Green Egg Large, Kamado Joe Classic models and compatible 18" kamado-style grills.

Built from thick cast iron with a matte finish, this 18 3/16" cooking grate replaces worn or missing grids on popular kamado grills and compatible models from brands like Big Green Egg, Kamado Joe and Vision Grill. Its heat-retaining construction promotes even searing and char while the pre-seasoned-style finish reduces sticking and simplifies cleanup. The grate matches common 18" part numbers (18CI, 18SS, 18P) so it’s a straightforward swap when your original grate has warped or corroded.

Will this grate fit my Big Green Egg Large or Kamado Joe Classic?

The BBQration 18 3/16" grate is designed to match the footprint of many 18" kamado-style cooking grids, including Big Green Egg Large and several Kamado Joe Classic models. Measure your existing grate or grill diameter to confirm the 18 3/16" dimension before ordering. The listing references common part numbers and compatible Vision Grill models to help compatibility checks.

• Nominal diameter: 18 3/16" — confirm against your grill’s grate diameter
• Compatible with Big Green Egg Large and Kamado Joe Classic I/II/III
• Also fits Vision Grill VGKSS-CC2 and several 18" Vision part numbers

How does the cast iron material affect cooking performance and maintenance?

Cast iron retains and radiates heat more consistently than thin steel, giving steadier searing and better grill marks. The matte cast finish helps food release when properly oiled, and the heavy construction resists warping at high temperatures. Routine care — drying after cleaning and applying a thin coat of oil — prevents rust and preserves the finish.

• Heavy-duty cast iron for even heat distribution and strong sear
• Matte finish reduces sticking when oiled before use
• Easy to maintain: scrub, dry, and lightly oil to prevent rust

What are the practical benefits for everyday grilling and high-heat searing?

The thick cast iron grate holds temperature when you open the lid, so you lose less heat during quick lid checks and can get a consistent sear across larger cuts. It also provides deep, attractive grill marks for steaks and firm vegetables while supporting heavier pans or griddles. For low-and-slow cooking, it keeps steady radiant heat beneath indirect setups.

• Improves searing and grill marks thanks to superior heat retention
• Supports heavy cookware and cast-iron accessories without bending
• Works for both direct high-heat and indirect low-and-slow setups

How should I season and protect this grate to extend its life?

After your initial cleaning, heat the grate and apply a thin, even layer of high-smoke-point oil to create a protective surface that reduces sticking and rust. After each use, remove food debris, dry the grate thoroughly, and reapply a light coat of oil while still warm. Store the grill covered in dry conditions to minimize corrosion between uses.

• Clean debris with a stiff brush; avoid prolonged soaking
• Dry completely, then brush on a thin coat of oil while warm
• Keep grill covered and dry when not in use to prevent rust

Who this is for: Grill owners who need a robust, long-lasting replacement grate for 18" kamado-style smokers and grills — particularly Big Green Egg Large, Kamado Joe Classic series, Vision Grill 18" models, and compatible aftermarket setups. Choose this BBQration cast iron grate if you want improved heat retention, stronger searing, and a durable surface that supports heavier cookware. Always verify the 18 3/16" measurement and part compatibility before purchase to ensure a correct fit.
