| 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.
|

|
| 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.
