Horizontal Cladding Top Hat System

Top Hat Sections
The Top Hat section offers a more economical solution for secondary supports to horizontal cladding. This is achieved by using a trapezoidal profiled section to span across multiple rails, to a maximum of 4.0m After this an introduction of a sleeve is required. Savings are made through reduction in cleats as the section bolts directly to the outer flange of the rails; cost effective profile with low manufacturing costs; and quicker erection procedures because of reduced member numbers. The Top Hat Section is available in two sizes, TH70 and TH140. The TH70 has a 70mm fixing face and is used for intermediate support to the cladding panels between joints. The TH140 has a 140mm fixing face as recommended by cladding manufacturers for panel joint connections.

Additional Restraint
In order to provide restraint to the inner flange of the rail section, strut members must be placed directly behind the Top Hat section. These are only required within the span.

Maximum Span
The Top Hat sections have been designed to suit standard 1.8m rail centres. They have capacity to span up to 2.0m but beyond this we recommend you consult our technical department.

 Non-Standard Top Hats
 Variations on Top Hat depth and width can be manufactured by Hi-Span on receipt of details.
