Mechanical cladding fixation

Steel back support systems

أنظمة الدعامات الفولاذية الخلفية

Where the structure cannot take the fixing directly, a secondary steel frame carries the cladding back to the slab.

Steel back support systems

A secondary steel frame is used where the backing wall cannot take anchors — lightweight blockwork, for example — or where the façade line stands far from the structure. The frame spans between slabs and the brackets fix to the steel rather than the wall. Members and connections are designed for each project.

KAVITY supplies the complete STANGLE system — L-, Z-, omega and fishtail brackets, corrugated dowels and studs, anchors and secondary steel — in stainless or galvanised steel matched to the exposure. Our technical department sizes it from your elevation, panel weight, cavity depth and wind load, and issues the structural calculation and shop drawings needed for consultant approval.
