Resi Flex ties are manufactured from grade 304 or, for more aggressive atmospheres, Grade 316 austenitic stainless steel. The 6.0mm diameter Resi Flex has a tensile strength in excess of 1.0kN. The manufacturing process produces fins that act as multiple drip points across the length of the tie, and a flexible core to allow normal movement.
The fixing in both leafs may also be achieved by the use of Bond Flex XL cementitious grout. Where there is a need for a fire resistance in excess of 30 minutes only Bond Flex XL Cementitious Grout should be used.
Epoxy resins are not recommended for normal installation as it has been noted that many of these resins are not reliable due to their accurate mixing requirements. Epoxy resins should only be used when fixing into diamond drilled holes.
