Hexmetal is a hexagon shaped grid used in the installation of thick linings. Hexmetal supports the lining and prevents slumps. It retards erosion, corrosion, cracking, blistering, pitting or collapse thereby lengthening the life of the lining. Hexmetal is recommended for use when placement is spaced from the steel shell to allow room for thick insulation between the steel shell and the armored surface. The slots permit passage of the castable which forms a key between adjacent cells. Available in standard and lance pattern.
