KAPU HE Passive Safe Lighting Columns

KAPU is a range of passively safe lighting columns from Signpost Solutions and manufactured by Sahko-Jokinen.

Safe choice

Sahko-Jokinen, established in 1968, is the largest manufacturer of impact-safe lighting poles in Europe. More than twenty years of experience, innovative product planning and high-quality technology have created the company’s position as a forerunner in the field.

KAPU – Durable Steel Cone Pole

KAPU safepole has been developed to improve the safety of road-users. The pole is best suited for roads that have heavy traffic and parallel walkways behind them. KAPU has been patented and it has passed the required tests for all speeds. Long life and low life cycle costs make KAPU the most suitable and durable choice.

Collision Characteristics

The cone-shaped KAPU safety pole has been approved to the standard EN12767’s best class 100, HE 3, 120km/h. The safety of travellers in collision situations is based on the pole’s structure. When a vehicle hits the pole, blocks in the pole’s body disengage, reducing the collision energy and allowing the vehicle to stop slowly and safely.

Experiences From the Roads

More than 30,000 KAPU safepoles were installed between 1994 and 2008. Approximately 400 poles have been hit, and in every case the poles have worked very well. More than 50 per cent of our production goes to the Nordic region, the Baltic countries and Central Europe. KAPU safepole is constructed from steel lamellas that have no extensions and have been attached together longitudinally. The structure meets the requirements of the EN 40-5 standard.


Steel is a familiar and reliable material for lighting poles. High-strength steel lamellas are cold formed into dimensional accuracy with computer-directed automatic machines. The material is hot galvanised according to EN ISO 1461. The screws used are made of stainless steel.

KAPU HE (High Energy) Passive Lighting Column

The unique patented structure of KAPU®-HE pole reduces the risk of injury to driver and passengers. The column absorbs the movement energy of the colliding vehicles and slows speed in a controlled manner to a safe level. See the image below for a pictorial example of this.
