Metal Column Covers |
| DESCRIPTION |
Structural columns of all materials, shapes and
sizes, e.g. metal, concrete, round, square, etc. can be covered with stainless
steel or aluminum column covers for lasting beauty, or aesthetic reasons. They
can also be used to conceal piping, electrical conduit and other services being
run within column spaces (with oroper access if necessary). Metal column covers
also offer protection against wear, durability, and savings in both maintenance
time and costs.
|
| Basic Use: |
| – |
Exterior or interior |
| – |
New construction or renovation |
| – |
Commercial and other applications |
| – |
May be used over square, round, rectangular or angular columns made
of steel, concrete, masonary, wood or other materials. |
| – |
may be combined with other materials e.g. marble, granite, tile, etc.
|
|
| Limitations: |
For non-structural (non-load bearing) use only.
|
Composition and
Materials
|
 Composition and
Materials: Solid 1.5 mm (.062") Type 304 stainless steel or up to 3 mm
9.125") aluminum is used to fabricate Kanalco column covers. Materials coming
from the mill in sheet form are finished to customer specifications, covered
with strippable, protective plastic film and then formedand fabricated as
required.
Flat
metal is brake formed; curved or rounded colum covers are either brake or roll
formed, depending on radius or direction of curve. Covers can be supplied in
1/2 circle, 1/4 circle or other configuration if desired.
Column covers can be fluted vertically
or horizontally as desired, for design effect and/or to facilitate
installation, as well as insulated where columns are located at mid-exterior
wall (half inside, half outside). Snap-in flute inserts can be provided in a
range of colours, or matching finishes.
Using internal members is the most
common method of stiffining and fastening of column covers. Requirements for
these members e.g. supports, fastening angles, alignment bars, subgirts,
brackets, clips, inserts, shims, etc. depend largely on the size and shape of
the column. Generally galvanized steel is used f

TECHNICAL
DATA |
Consult with Kanalco Ltd.
|
| INSTALLATION |
Methods: Kanalco Ltd. are a custom
manufacturer specializing in the metal fabrications field. Installation of
Kanalco stainless steel and aluminum products is normally carried
out by the appropriate trades and experienced installers according to
specifications and approved shop drawings.
|
AVAILABILITY
& COSTS
|
Kanalco fabricated metal products can be
shipped anywhere in North America. Current cost data is available upon request.
|
| WARRANTY |

|
| MAINTENANCE |
For stainless steel and aluminum finishes, in most
instances, only a periodic warm water wash and drying with a soft cloth is
sufficient to restore the original lustre.
However, depending on the severity of dirt accumulation,
more elaborate cleaning procedures may be required. Consult with Kanalco for
additional data.
In
the case of mirror-like stainless steel finishes, e.g. X-L Buff, the foregoing
is still applicable however commercial creams are available which provide added
lustre to these finishes.
