double lock standing seam system
The Double Lock Standing Seam System is a further development
of the original hollow folding joint or single standing seam used for
zinc material. First described in technical literature in 1899, it is the
preferred method of application for roofs with a slope of 6 in 12 or
less with a minimum slope of 5/8 in 12.
With a minimum seam height of 1” (25 mm), the double lock is
measurably more weather resistant than the angle lock and is the
preferred seam type for most roofing applications; especially for
low slope roofing.
Sometimes prefabricated in profiles with a seam height of 1-1/2”
(38 mm), it has become an international standard. Bending and
closing the panel seams can be done manually or mechanically
using electric seaming machines.
Special designs such as convex and concave curves or conical
assemblies can be fabricated without difficulty. Due to the range
of possible variations in its detailing, the fine linear design of the
Double Lock Standing Seam complements both traditional and
modern architecture.
angled standing seam system
The Angled Standing Seam System is a 20th century development.
It is used on roofs with a minimum slope greater than 6 in 12.
Simply folding in one leg of the joint, creates the finished Angled
Standing Seam System. The Angled Standing Seam System is
particularly suitable for visible areas of the design of steep metal
roofs and for parapets and mansard slopes, etc. With a visually
broader seam, than that of the Double Lock Standing Seam, the
Angled Standing Seam gives applications with a large surface area
a lively and striking appearance.
