Hexsteel (hex metal) 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.
