| 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 (optional): |
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).
