Fire burned board is made by burning the surface of granite with liquefied gas and oxygen through a high-temperature flame. Due to uneven heating and different expansion, it forms some slight bumps and depressions like lychee surface, which has anti slip effect. Fire burned boards can be applied on sidewalks, highways, indoor floors, and walls. Fire burned surface is mainly used in municipal paving projects (such as sidewalks, squares, and community beautification). In order to prevent slipping, the stone cutting surface is treated with high-temperature fire to form a "rough and bold fire burned surface". The burnt surface can also be used as an external drywall for hanging.
