Horizontal Cladding Alignment

Tighter tolerances are associated with some of the horizontal cladding systems in today’s market. These tolerances can be achieved by using Metsec C-section rails supported on cleats with slotted holes in combination with the slotted cleats in the PJR and HCS.

Metsec have carried out comprehensive testing at The University of Strathclyde to support the use of slotted cleats without slip under the required loads. The recommended torque on a grade 8.8 bolt is 244Nm. The results of these tests are shown in the table below and are applicable to Metsec components.
