The design must be such that it balances the need for a tight seal with the amount of friction generated during operation. Excessive friction can lead to wear and heat buildup, while insufficient sealing can allow fluid leakage. Therefore, engineers carefully select materials and dimensions to ensure optimal performance.

Another key factor to consider is the grill's construction material. Most charcoal grills are made from either steel or cast iron. Steel grills tend to be lighter and more affordable, but those with porcelain enamel finishes provide better heat retention and are more resistant to rust. On the other hand, cast iron grills are renowned for their excellent heat retention and distribution, offering the ability to sear meats perfectly. However, they can be heavier and require more maintenance to prevent rust.
