Upgrade Motivation and Installation
My Charbroil infrared grill originally came with standard metal grates. These, however, proved problematic. Food stuck, juices would flare up excessively, and the risk of a grill fire was a constant worry. This prompted the upgrade to cast iron grates.

The installation process was straightforward. The cast iron grates replaced the existing metal ones directly. There were no modifications needed to the grill itself. The improvement in the grilling experience was immediately apparent.

Performance and Heat Retention
The most significant difference is the superior heat retention of the cast iron grates. They maintain a more consistent and even temperature across the entire grilling surface. Food cooks more evenly and efficiently.

The cast iron's ability to retain heat also improved sear marks significantly. The improved heat distribution resulted in better overall cooking performance. The elevated cast iron grates are also separated from the bottom metal sheet, leading to better airflow.

Addressing Previous Issues
With the new grates, the issue of food sticking is completely resolved. The cast iron surface seems to have a natural non-stick quality, especially after a proper seasoning.

Another major improvement is the control over flare-ups. While some flaming is still present (which is desirable in infrared grilling), it's now much more manageable and less likely to ignite the entire grill.

Overall Conclusion and Recommendation
Upgrading to the cast iron grates was a worthwhile investment for my Charbroil infrared grill. The improvement in heat retention, ease of cleaning, and reduction of flare-ups significantly enhanced the grilling experience. The cast iron grates provide a superior cooking surface compared to the standard metal ones.

For anyone considering a similar upgrade, I highly recommend making the switch. The benefits far outweigh the cost. The upgrade improved the overall grilling experience and resolved the issues present with the previous grates.
