grill block

Common materials include stainless steel, other steel/metal alloys, and aluminum. Some cooking trays use plain (natural) aluminum with reinforced rims for added strength.

Many portable camp grates use foldable legs or a fold-in-half design so the unit collapses flat for storage and transport. Some models also include carry handles to make lifting and moving easier.

Weight capacity varies by design: some round or half-moon grates list about 15 lbs per section, tripod-style grates list up to 20 lbs, and larger folding grates state capacities up to about 30 lbs total.

Tripod grates commonly offer adjustable grate heights (for example, about 14"–23" above ground). Charcoal grills may include a height-adjustable charcoal pan, dual air dampers for airflow control, and a built-in thermometer for more precise heat management.

Options include electric tabletop and indoor smokeless units, propane (liquid-petroleum) for some outdoor grills, charcoal grills with adjustable charcoal pans, and open-fire camp grates intended for use over campfires.
