Key points
How horizontal step panel systems use panel sizing, joint planning and fabrication coordination to respond to curved, fan-shaped and special roof forms.
The value of horizontal divisions
Horizontal joints can break a complex roof form into a controlled architectural rhythm and make the relationship between the roof and façade easier to coordinate.
Geometry comes first
Curves and fan-shaped roofs require early confirmation of radius, panel direction, joint spacing, drainage and fabrication limits.
Where detailing is essential
Edges, transitions, gutters, end closures and connections should be resolved before production so the visual rhythm and waterproofing logic remain consistent.
