Aluminum Plate

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.

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.

Basic Use:
– Exterior or Interior
– New construction or renovation
– Commercial and other applications
– Typical and architectural use examples include:

  • exterior wall panels
  • enclosure panels for lobbies and mezzanines
  • entrance way treatments
  • store fronts
  • fascia panels
  • flashing
  • ceiling panels, soffits
  • spandrel panels
  • beam enclosures
  • column covers
  • escalator panels
  • partitions
  • wall trim and accent strips

Limitations: For non-structural (non-load bearing) use only.

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.

  1. 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: 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:
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 reciprocating 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 fluorocarbon coating system – Duranar A.D. (contact a Building Product Sales Office for further information).
