Mechanically fastened extruded aluminum has been an Industry standard for many years.
Construction Specialties, Inc., has engineered and furnished thousands mechanically fastened
SunShade systems. We have furnished mechanically assembled products on thousands of jobs
throughout the world.
Technical Information
Construction Specialties, Inc., has chosen mechanical fastening over welded construction for
the following reasons:
Configurations
including adjacent
blade overlap,
make access to the
weld areas
extremely limited.
In the shadow of
the blades, welds
appear dark. In
direct sunlight
welds appear as
bright spots from
all angels.
Welding reduces
outrigger strength. Will
the outrigger fail? Do
the calculations
provided by the vendor
allow for reduction?
Actual installation of a major competitor’s Welded SunShade
If a weld should crack during
shipment, handling and/or
erection, or if the SunShade is
damaged, repair of welded
louvers is extremely difficult.
Welded areas are highly
visible from the interior
and exterior of the
building.

Mechanical Fastened vs. Welded Assembly
Mechanically assembled extruded aluminum has been an industry standard as well as C/S standard
since they were first marketed in the 1940’s.
♦ Configurations including adjacent blade overlap, make access to the weld areas extremely limited. It
is very difficult to perform and inspect the tack welds to insure quality welds with full penetration
through the joint.
♦ If a weld should crack during shipment, handling and/or erection, or if the louver is damaged, repair of
welded louvers is extremely difficult. Adjacent welds must be broken to provide access and all broken
welds must be cleaned off by chipping or machining. All finishes around the weld must be removed by
sanding to prevent contamination of new welds. This causes substantial costs and delays.
Mechanical Fastened
Mechanical Fastened SunShade’s add a clean,
smooth, esthetic appeal to a building.
