Aluminum Wall Panels
|
|
| DESCRIPTION |
The popularity of aluminum as a
building material can be attributed to the following:
Formability: A unique combination makes
aluminum one of the most versitile of engineering and construction materials.
It is highly ductile and formable.
Lightweight: Aluminum is
probably best known for its light weight, only one-third that of steel. But it
can also be made very strong - some of its alloys are stronger than some
structural steels. In addition, preformed aluminum panel systems are known to
exceed the strength and fabrication capabilities of composite panels at no
increase in cost.
Easy Maintenance: Painting or
refinishing of aluminum products is eliminated. The only cleaning generally
required is washing with detergent and water. In inaccessible areas, rainfall
is normally sufficient to keep aluminum clean.
Attractive Appearance: Aluminum is a bright,
clean-looking material that blends well with all kinds of building materials.
It readily accepts a wide variety of surface finishes.
Finish
Integrity: An important property of aluminum is its chemical affinity
for oxygen, which causes it to form a thin, tough, invisible and impervious
film of oxide on its surface immediately on the metal's exposure to air which
is virtually impenetrable by the atmosphere once it has formed. Finishes adhere
very tightly to the metal; this means that there is no flaking off of the oxide
and continuous corrosive attack of the surface, and no coloured wash-off to
stain ajacent surfaces.
Cost: The cost comparison of
building materials is unrealistic if only initial outlay is considered. Total
cost includes insurance, maintenance, custodial care, replacement and other
factors. Of these, maintenance generally represents the highest cost. Aluminum
is recognized as a long-lasting, easily maintained material for both interior
and exterior architectural applications. Its smooth, dense, corrosion-resistant
surface minimizes the adhesion of dirt and maintenance.

Composition and
Materials
|
 Solid 3 mm (.125") aluminum alloy
(5005-H34 anodizing quality or 3003-H14 paint quality tensioned levelled sheet)
is used to fabricate the many Kanalco architectural products,
however other thicknesses or alloys are available. Materials, coming from the
mill in sheet form are finished to customer specifications, covered with
strippable, protective plastic film and then formed or worked as required.
Flat metal is brake formed; curved panels are either brake or roll
formed, depending on the radius and direction of curve. Corners of pan-formed
panels can be welded and ground smooth
Kanalco panels may be supplied as a composite panel
with insulated core and flat liner sheet backing if desired. See accessories
below.
|
|
| Finishes: |
The following aluminum finishes are offered as standard
by Kanalco:
Anodized finishes: Architectural
Class 1, 20 um (.0008") or Class 2, 10 um (.0004") in clear or standard
colours.
Paint finishes: PPG Duranar flourcarbon coatings
containing Kynar 500* resin in a wide range of architectural
colours.
|
|
Accessories

1. Glass fiber insulation of thickness,
density and thermal value as required.
2. Flat liner sheet of factory formed commercial
quality aluminum. |
|
| Sizes: |
Width: Coil or sheet is available in up to to
1829 mm (72") width and may be slit to smaller widths.
Length: As desired, depending on
material availability.
Thickness: 3 mm (.125") is standard. Other thicknesses
available.
Radiused
Corners: - 6 mm (1/4") minimum.
|
|
| Shapes: |
Brake or roll (roller die) forming can produce an
infinite variety of shapes. Kanalco can advise on proposed design
configurations upon request.
|
|
Applicable
Standards: |
Kanalco aluminum
fabrications conform to:
CAN/CGSB-93.1M
Aluminum Association Designation System for Aluminum Finishes (clear
or colour anodized)
AMA
#605 for Duranar coloured coatings "Voluntary Specification for High
Performance Organic Coatings on Architectural Extrusions and Panels".

|
TECHNICAL
DATA |
Comprehensive data relating to physical and mechanical
properties of aluminum can be found in AAMA technical literature available upon
request from Architectural Aluminum Manufacturers Association, Washington, D.C.
|
|
| INSTALLATION |
Methods: Kanalco Ltd. are a
custom manufacturer specializing in the metal fabrications field. Installation
of Kanalco aluminum products is normally carried out by the
appropriate trades and experienced installers according to specifications and
approved shop drawings.
|
|
| Precautions: |
 Precautions:
Brackets, clips or other fixing devices, when made from another metal, should
be insulated from the aluminum by bitmastic or similar insulators to prevent
corrosion or possible unsightly "bleeding" of other materials.
Eliminate drainage from other materials,
such as chloride bearing cements and other corrosive materials.
Fasteners should be
concealed as much as possible for aesthetic reasons, and should have corrosion
resistance equal to or better than aluminum to eliminate future repairs. If
possible always use stainless steel fasteners.
The designer's specifications should
make clear to all trades whose work adjoins the aluminum panels that suitable
precautions against damage must be maintained.
|
|
| Building Codes: |
Kanalco metal building panels comply with
the National Building Code of Canada and the various provincial
codes.
|
|
AVAILABILITY
& COSTS
|
Kanalco fabricated metal products can be
shipped worldwide. Current cost data is available upon request.
|
|
| WARRANTY |
Normal 1 year construction warranty.
|
|
| MAINTENANCE |
To keep aluminum architectural
components attractive, adefinite maintenance program must be followed. The
frequency of cleaning will depend on:
- atmospheric environment and severity of pollution
- effect of weathering
of the aluminum finish and ability of the finish to shed dirt and grime.
- cost involved.
- owners interest in
retaining the original appearance.

|
| Cleaning Methods |
Cleaning Methods:
Anodized
finishes (in order of increasing severity)
1) Wash with clean warm water; dry with a soft cloth.
2) Wash with mild soap
or detergent and water; scrub with a stiff bristle brush; rinse and dry.
3) Apply solvent-type
cleaner (kerosene, naptha, turpentine); rinse to avoid streaks and dry.
4) Use a proprietary
polish cleaner as directed by the manufacturer; rinse to avoid streaks and dry.
5) Apply a mild
abrasive cleaner with a damp cloth (jute is very effective) or soft brush;
rinse with soap and water, then with clean water.
6) Use a strong abrasive cleaner applied
either as in 5 or with a recriprocating power tool. This method should be used
only as a last resort because it destroys the anodic finish.
Note: Refer to the appropriate AAMA
literature for more detailed cleaning data e.g. suggested frequency of cleaning
etc.
Duranar
Finishes:
Duranar coatings require very little maintenance. Most surface
residue may be removed using conventional detergents or solvents. Harsh
chemicals or solvents and abrasive materials must not be used on Duranar
coatings. Minor scratches can be touched up with a specially formulated air-dry
flurocarbon coating system - Duranar A.D. (contact a Building Product Sales
Office for further information).
