New Telegraph Poles
Ordering
Overview
Telegraph poles are an essential part of the construction world, whether for supporting cables, or construction and landscaping:
~ telephone/electrical ~ roof supports ~ bridges & walkways ~ architect columns ~ edging & retaining ~ river embankments ~ marinas & moorings ~ platforms & decking ~ gate posts & fencing ~ adventure play areas ~ treehouses. The list is endless!
General 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.
BRITISH STANDARD 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. Published Date: 28/09/1984
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 telegraph poles and they are graded into sizes (light, medium and stout) and stacked for seasoning. Telegraph poles are dried naturally by air. This process begins when first harvested and continues once they have been shipped to the UK, where 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 telegraph poles are consistently moisture tested, and are not pressure treated until their moisture content is below 28%.
DRESSING In order to provide a smooth surface to all the telegraph poles, they are dressed - peeling the outer cambium layer with an automatic dressing machine.
TREATMENT Your telegraph poles can be treated with one of two treatments:
1) AC500 Treatment is a non-creosote, environmentally friendly, water based pressure treatment similar to Tanalith E treatment. AC500 treated telegraph 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 telegraph poles cannot be used, due to recent creosote legislation. AC500 treated telegraph poles do not emit anything in the heat of the summer, whereas creosote treated telegraph poles may bleed or leak sticky creosote when it's hot, and there's nothing you can do to prevent it. AC500 treated telegraph poles are sometimes used by local authorities who have a policy against creosote.
2) Creosote Treatment gives your timber telegraph pole the longest life span possible and protection from harsh conditions. Pressure treated creosoted telegraph poles provide a minimum desired service life of thirty years, but may last considerably longer. Indeed there are numerous examples of telegraph 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, 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. For further information on creosote visit WOOD TREATMENTS
FIXING IN GROUND Timber telegraph poles can be placed directly into the ground, and generally do not require concrete foundations or collars to prevent deterioration. Typically, a 9m pole will be inserted between 1 - 2 metres into the ground, depending on ground conditions.
CUTTING You can cut telegraph poles to size with a chainsaw, circular saw or even handsaw if you are feeling energetic!
SIZE, WEIGHT, DIAMETER etc.. Telegraph poles 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 telegraph poles forget it ! We classify new telegraph poles into broadly 3 diameter ranges - 'Light' , 'medium' and 'stout'. SEE BELOW for all the diameter, weight and strength specifications for new telegraph poles.

Extra Info
TELEGRAPH POLES ARE DELIVERY BY AN ARTIC LORRY WITH CRANE OFFLOAD
Our specialist telegraph pole lorries can offload themselves with a hiab crane. Your order can be crane-offloaded so long as there is space for the artic crane to operate without lifting over vehicles etc..You must ensure in advance that there is sufficient access space for the lorry to approach, manoevre and park. We will send you an artic access questionnaire, with all the required access space dimensions, to fill in before the delivery.
ARE YOU A LOVER OF TELEGRAPH POLES?
Yes, there is a genuine Telegraph Pole Appreciation Society that has featured our website, and is a wonderful blend of information and eccentricity! Pay them a visit! http://www.telegraphpoleappreciationsociety.org
