Flex metal refractory lining is the direct counterpart of hex metal, it performs all the same functions of reinforcement of thin wall refractory linings, while its design allows free form rolling to very small diameters. Hex metal becomes impractical to use when the section of plant being protected is of small diameter, the free rolling capabilities of flex metal allows plant as small as 150mm to lined. Typical applications include air distributors, fan cases and all plants where the practicality of free rolling material is beneficial to maintenance activities.
