4.10 Installation of sheet seam clamps
Special fastening elements are used to fasten PV modules on standing seam roofs, which are then
attached to the carrier rails.
The roofing must not be damaged by the load on the installed clamps. For this reason, we recommend
having sheet seam clamps fitted by a roofing company.The tightening torque of the sheet seam clamp
must be limited in such a way that the sheet metal is not deformed and the thermal expansion of the
sheets is not hindered.
The clamps are mounted vertically according to the number of carrier rails. As a
rule, fit one standing seam to each clamp. On each side the carrier rail must
protrude by a maximum of 0.3 m. Observe the thermal separations of the profiles
after 3.1m or the spezifications of the respective sheet seam manufactures.

Important!
Clarify on site whether the roof and the substructure are able to withstand the additional forces caused by
installing the PV system. If you intend to assemble PV plants on standing seam roofs, the roof must not
only carry the additional loads, it must also withstand the additional wind dynamics. A structural engineer
must check the number of fixing points (sheet seam clamps) according to the on-site conditions. Keep the
alternator size to a minimum to minimise occurring voltage values. A connection on titan's zinc roofs or
copper roofs is not recommended. In advance the clamp should be checked for correct fit and material
compatibility.

Please also take into account the manufacturer's specifications for the corresponding roofing, as
well as the specifications of the corresponding general building approval Z-14.4-560!

Version 17.01, as of: 27-Jun-2017
Use "Kalzip® clamps" to fasten the system on so-called Kalzip® roofs. The
clamps are distributed vertically according to the number of cross girders. As a
rule, fit one standing seam to each clamp. On each side the carrier rail must
protrude by a maximum of 0.3 m.
