Vankey 11.5in Cast Iron Fire Grate for Kamado Joe Big Joe — Reinforced Charcoal Plate, Easy-Clean

Vankey’s 11.5-inch round cast iron fire grate is a heavy-duty replacement charcoal plate designed to restore airflow and even heat distribution in Kamado Joe Big Joe grills.

If your Kamado Joe Big Joe has uneven burning, difficulty holding temperature, or you need a sturdy replacement for a damaged charcoal plate, this cast iron fire grate is engineered as a direct-fit upgrade. Built with horizontal and vertical reinforcing tendons, small precision pores, and a flat, easy-to-clean surface, it improves combustion efficiency while resisting warping at high temperatures.

How does this grate improve airflow and fuel efficiency?

The grate’s high-density 5/8-inch pores keep coal from falling through while channeling more oxygen to the coals, accelerating startup and stabilizing burn. Better airflow means coals reach target temperatures faster and stay lit with less charcoal.

• 5/8" pore pattern increases oxygen flow without losing embers
• Dense pore layout creates a consistent combustion zone
• Promotes hotter burns using less fuel for shorter preheat times

Will this cast iron plate resist high heat and deformation?

Yes — the design adds reinforcing tendons across the underside of the plate, horizontally and vertically, to strengthen the structure against prolonged high-temperature cycles. The cast iron composition holds shape under repeated heating and cooling so the grate lasts longer than thin metal replacements.

• Cross-tendon reinforcement prevents bending and cracking
• Thick cast iron body tolerates repeated thermal stress
• Engineered for long-term durability in high-heat environments

Is this an exact fit for Kamado Joe Big Joe grills and easy to clean?

This replacement is sized to 11.5 inches to match Big Joe firebox dimensions — measure your grill before ordering to confirm fit. The top surface is flat and smooth, so ash and grease brush off easily and there are no hard-to-reach crevices to trap residue.

• Designed for Kamado Joe Big Joe series (measure to verify)
• Smooth surface simplifies ash removal and scrubbing
• No fiddly gaps or deep cavities that trap grime

How does this grate affect cooking consistency and temperature control?

By improving oxygen flow and stabilizing the coals, the cast iron grate delivers a more uniform heat field across the firebox. That helps maintain both high searing temperatures and low-and-slow settings with less charcoal and fewer temperature swings.

• Encourages a steady bed of embers for consistent heat
• Reduces hot and cold spots for even cooking results
• Speeds recovery after opening the lid, maintaining set temps

Who this is for: Grill owners with a Kamado Joe Big Joe who want a rugged, long-lasting cast iron fire grate to improve burn efficiency, make temperature control more reliable, and simplify cleanup. It’s ideal for backyard chefs who prefer fewer charcoal changes and more predictable heat for searing, smoking, and everyday grilling.
