General information
Kalzip AF und AS:
With Kalzip AS and AF profiled sheets, an in -
crease in construction width of up to 20 mm
must be taken into account following curving,
so that an overlap with straight sheets
is not possible.
Smooth-curved Kalzip AF profile sheets can
show signs of increased buckling in the
base plate. As it is impossible for tech nical
production to prevent this buckling, it will
not be accepted as grounds for complaint.
When the optical characteristics of a building
are of increased importance, then
smooth-curved Kalzip AS profile sheets
should be used instead.
Standard:
Constant radius with a short (approx. 400
mm) straight segment at the beginning and
the end of the profile sheet. Any radii below
the standard minimum as well as multiple
radii and/or straight elements in one Kalzip
sheet must be agreed with our technical
department in Koblenz.
It is unavoidable that inter mediate radii occur
in the transition area of different radii as well
as between curved and straight sectors.
Clips must not be located in these areas.
Tolerance limits. Only after consultation
with our technical department in Koblenz.
Special measures are necessary in order
to reach the tolerance limits.
Finish:
• stucco-embossed
• AluPlusPatina
• coated material with protection foil
• AluPlusZinc with protection foil
• Anti-condensation coating on request
Installation width:
For pre-installed clips:
cover width + 3 mm
successive installation of clips:
cover width + 0 to + 3 mm
Length of profiled sheet:
Minimum length 1.5 m. Shorter lengths on
request. The final overall length depends
on the individual radii and possibility of
transport. Minimum length of segment per
radius = 500 mm.
Transportation:
Maximum loading height 2.4 m. It might be
necessary to coordinate details of transportation
with our logistics department.
Transitional area:
If a Kalzip profiled sheet is roll-curved with
several radii, a transitional area is created
in which no clip may be placed (except a
fixed point clip).
This transitional area can be safely estimated
to be ± 300 mm (600 mm in total) if the
two adjacent radii both have the same sign
has, or ± 600 mm (1200 mm in total ) if the
two adjacent radii have different signs, i.e.
from concave to convex or vice versa. It is
necessary to consult the Application Technology
Dept. in Koblenz for a more exact
determination of this transitional area.
