INFORMATION about new telegraph poles
Telegraph poles have been used for decades
to carry overhead telephone, powerline and computer cables, as well as for
construction and landscaping projects.
All our Telegraph
poles adher to BS 1990: Part 1 1984, Wood poles for overhead
power and telecommunication lines, Part 1. Specification for softwood poles.

TYPE OF WOOD
Normally our telegraph poles are made from
Redwood or Scots Pine (Pinus Sylvestris). All
the poles are FSC or PEFC chain of custody certified, meaning that all the
trees that are harvested come from sustainable managed forests.
FROM THE VERY BEGINNING
After harvesting, the bark is taken off our poles and they are graded into
sizes (light, medium and stout) and stacked for seasoning.
Poles are dried naturally by
air. This process begins when first harvested and continues once they have
been shipped to the UK, they are moisture tested again and laid out for further
seasoning. They are left for up to twelve months to complete the natural drying
process. During this time poles are consistently moisture tested, and are
not pressure treated until their moisture content is below 28%.
In order to provide a smooth surface to all
the poles, they are dressed - peeling the outer cambium layer with an automatic
Your poles can be treated with one
of two treatments.
AC500 Treatment is a non-creosote, environmentally
friendly, water based pressure treatment similar to Tanalith E treatment.
AC500 treated poles can be used for standard telegraph pole purposes, and
in addition CAN be used for children's play areas, tree houses, inside
houses etc.. where creosote treated poles cannot be used, due to recent creosote
legislation. AC500 treated poles do not emit anything in the heat of the summer,
whereas creosote treated poles may bleed or leak sticky creosote when it's
hot. There's not much you can do about it! AC500 treated poles are
sometimes used by local authorities who have a policy against
gives your timber pole the longest life span possible and protection from
harsh conditions. Pressure treated creosoted poles provide a minimum desired
service life of thirty years, but may last considerably longer. Indeed there
are numerous examples of poles in service which are over 100 years old!
Creosote has been used for
over 150 years to preserve and increase the life-span of timber. Recent findings
have indicated that creosote can be harmful in certain situations. So, in
order to be careful: Handle with gloves. Wear a dust mask when sawing
or machining. Dispose of off-cuts, sawdust etc.. safely. Waste wood may be
disposed of by burning, subject to any local rules on burning creosoted material
in the open, or via your local waste disposal facility.
Creosoted timber should not be used where there is risk of
frequent (i.e. often-occurring or constant) skin contact, nor where it may
come into contact with or contaminate animal or human foodstuffs. In particular
it should not be used inside buildings, in playgrounds, or for garden furniture
and picnic tables.
FIXING IN GROUND
Timber poles can be placed directly into the ground,
and generally do not require concrete foundations or collars to prevent deterioration.
SIZE, WEIGHT, DIAMETER etc..
They vary in length, weight, diameter and taper. Not only is every pole
different in dimensions from each other (like each tree) but also they are
tapered along the length. So the diameter of a new telegraph pole will vary
from top to bottom. In addition the very end of the pole (the original base
of the tree) can broaden out even more. So, if you are looking for
absolute regularity and identical poles forget it ! We classify new
telegraph poles into broadly 3 diameter ranges - 'Light' , 'medium' and 'stout'.

We can cut new poles to size
if you don't have the facilities, or if it speeds
up your project. We can 'cross-cut', e.g. cut a 9m pole down to 5m. We
charge £5 + Vat per cross cut. Alternatively you can cut them yourself
with a chainsaw or circular saw.
