Panel Joint Rails and Horizontal Cladding Supports
For economy, it is recommended that Metsec horizontal cladding supports with riveted end cleats are used as vertical supports to the horizontal cladding panels.
Joints in panels may require a wider flange for fixing purposes which can be provided by using a Metsec panel joint rail.
Alignment of the steel face can easily be achieved by adjustment of the horizontal rails on slotted cleats at the stanchion position.
Metsec have carried out comprehensive testing at The University of Strathclyde to verify the adequacy of this type of support without slip under the required load. See Horizontal Cladding Alignment for test results.
In order to achieve the alignment tolerances associated with some horizontal cladding systems, it is recommended that C-section side rails are used in conjunction with HCS or PJR as vertical supports. Additional local adjustment is provided by slotted holes in the HCS and PJR fixing cleats.
The maximum spacing of vertical supports to horizontal panels is shown and is necessary to provide adequate restraint to the rails. If this cannot be achieved, please refer to Metsec for advice.
Sequence of erection of the side rails, side rail supports and diagonal tie wire restraints is similar to the recommendations shown on Vertical Cladding Restraint Requirements and Vertical Cladding Restraint Fixing Details.
Note: rail alignment and cladding support to be provided by the steelwork contractor.
