Reliable protection with a guaranteed service life of up to 80 years. A certified solution for the harshest climatic and soil-related conditions worldwide.
As a wood-pole manufacturer, induo® subjects carefully selected wood poles to a rigorous pressure process.
Maximum protective barrier through the Rüping process: Using a special plant and vacuum-pressure technique in the proven Rüping process (pressure impregnation), we achieve a controlled minimum application quantity of 95 to 140 kg of preservative per cubic metre (m³). Our creosote poles thereby fully penetrate the sapwood zone. They form an impenetrable barrier against extreme weather phenomena - the ideal foundation for global telecommunications and energy supply.
As a direct supplier, you benefit from maximum efficiency when buying from us: you bypass unnecessary intermediaries and receive goods with precisely calculated technical parameters directly ex works. For every wholesaler and contractor, the Rüping process guarantees a flawless surface with no bleeding - for smooth handling from loading through to final installation.
In contrast to traditional methods, the advanced Rüping process begins with the build-up of an initial pressure of 100-700 kPa.
Then hot creosote oil (heated to 105°C - 140°C) is pressed directly into the cell structure of the entire sapwood area.
We guarantee a minimum retention of the agent of 95 to 140 kg per cubic metre of wood.
The process ends with a final vacuum phase. The expanding air pushes out excess impregnation agent and completely prevents the poles from “dripping” during storage and weeks-long sea transport.
Creosote-treated poles form the proven infrastructure skeleton that is irreplaceable where other methods fail. They offer certified protection for the harshest climatic and soil-related conditions worldwide.
Main areas of application and target markets
We offer tailor-made solutions for global network expansion and make a significant contribution to network expansion in Great Britain, Ireland and many other countries. Our portfolio includes high-load telephone poles as well as classic telegraph poles, manufactured in full conformity with the British standard BS 1990 and ENA TS 43-88.
Our poles seamlessly cover the critical and mechanical requirements of modern energy networks. We supply precisely configured wood poles for:
Our creosote-treated poles have proven themselves sustainably in the Arab markets, in the Middle East and in North Africa. Thanks to our reliable production capacities, we handle complex large-scale orders for leading state energy companies - such as GECOL (General Electricity Company of Libya) - with absolute precision and on schedule.
We supply 100% finished utility poles - already drilled, with a correctly sawn pole top and permanently marked with a precise nameplate and ID plaque for seamless traceability, adapted to every delivery schedule. We handle the complete logistics for you to the desired delivery location - whether by land or sea transport.
Whether you are handling a strategic tender for a state grid operator or replenishing stocks - with us you have the certainty of stable quality, standards and optimal prices. Configure the dimensions (e.g. lengths up to 16 m), the butt diameter and your specifications.

Yes. As wood does not corrode, creosote-impregnated wood poles are particularly suitable for locations with salty air, coastal proximity or aggressive climatic conditions.
Creosote-impregnated wood poles have a very high electrical resistance and poor conductivity. Wood is by nature a good insulator, and the creosote impregnation does not significantly change this property either. Wood poles therefore offer a technical advantage over conductive materials such as steel, particularly in the field of power and telecommunications lines.
Creosote-impregnated wood poles are designed for particularly demanding soil and climate conditions. Their actual service life depends on factors such as soil moisture, salt load, biological activity, wood species, impregnation quality and regular inspection.
In practice, professionally impregnated wood poles frequently achieve service lives of 40 to 60 years even in difficult soil conditions. Under favourable operating conditions and with appropriate maintenance, considerably longer service lives are also possible.
For our induo® creosote-impregnated poles, we use exclusively high-quality Nordic pine (Pinus sylvestris). Thanks to its natural structure, this wood species is particularly well suited to the production of durable wood poles.
A decisive advantage of Nordic pine is its pronounced sapwood zone. It enables a deep, uniform and durable uptake of the wood preservative. As a result, the creosote impregnation can penetrate effectively into the protection-relevant areas of the wood and ensure long-term protection against moisture, fungi, insects and biological decomposition.
In comparison, spruce wood - especially after drying - can only be impregnated to a very limited extent and exclusively at the surface. For this reason, spruce poles are not approved in almost all international specifications for power and telecommunications lines.
The use of Nordic pine is therefore a central quality factor for us: it combines high mechanical strength, very good impregnability and lasting durability - ideal conditions for reliable wood poles in the international energy and telecommunications sector.
