Metal Hex grid is also known as hex metal, hex metal grating, hex steel mesh, Hex steel grill or hex steel grid. Metal Hex grid provides surface framework for reinforcement of the refractory or concrete material in linings. They are made of pressed strips riveted to each other to form the hexagonal apertures.
Hex metal refractory lining is a hexagonal cellular mesh grating specifically designed for reinforcing both linings and flooring. The hex steel mesh 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
