Fire bars are metal grates used in fireplaces, stoves, and fire pits to hold burning logs or charcoal. They allow air to circulate around the fire, promoting better combustion and heat distribution. Fire bars are typically made from durable materials like cast iron or steel, which can withstand high temperatures. These bars come in various designs and sizes to fit different types of fireplaces or fire pits. Properly installed fire bars can enhance the efficiency of a fire, making it burn longer and more evenly. They also help protect the structure of the fireplace by keeping the fuel off the floor.
