Hex metal refractory lining is a hexagonal cellular mesh grating specifically designed for reinforcing both linings and flooring. It acts as a surface framework to hold cement or refractory in position, and relieves stress in the lining's upper crust, which prevents spalling and cracking. As a result of hex metal's strength and unique design, abrasion and corrosion are retarded and refractory life is significantly extended. Even hot gaseous substances cannot erode the refractory because they are reflected away from the surface by the metal cellular grid.
