Fuse masts
The DESCHAMPS MATS COMPOSITE fusible pole: an essential safety device.
A key element for the protection of road infrastructure.
What is a fusible pole?
A DESCHAMPS fusible pole is a type of pole specifically designed to break under applied force, typically in the event of a vehicle collision. Unlike traditional poles that can remain firmly anchored to the ground, DESCHAMPS fusible poles are designed to break or detach from their base, thus reducing the force of the impact. These poles are often used to support traffic signs, lampposts, or other objects essential to road safety.
Design principles
The first application of this technique appeared in the 15th century when Godefroy Deschamps,* then a squire, had the idea of weakening lances so that, during jousts, the lance would break upon impact, preventing knights from being injured or killed.
Unfortunately, in 1547, the death of King Henry II during a jousting tournament in Milan brought an end to this exciting sporting event.
The historical reality of this event is not entirely established 😊
In 2022, DESCHAMPS MÄTS COMPOSITE took up the mantle, aiming to utilize this property for other applications.
Their design incorporates materials that allow the pole to break in a controlled manner when a certain force limit is exceeded.
Two methods are used on DESCHAMPS fusible poles: the breaking of the tube itself near its base by reducing the characteristics of the materials themselves, the second is the breaking of the base itself by its shape and innovative structure, called the "VV" process for Verre Vorgé.
Applications in road infrastructure
- Road signs
- Street lighting
- Construction and work zones
- SNCF level crossing
Advantages of DESCHAMPS COMPOSITE Fuse Poles
Increased safety. The primary advantage of fusible or frangible poles is safety. By minimizing the energy transferred to the vehicle during a collision, they reduce the risk of serious injury to occupants.
Cost reduction
Fuse poles also help reduce the costs associated with infrastructure and vehicle repairs, as their design prevents major damage.
Ease of replacement
Because of their controlled breaking mechanism, fusible poles are easy to replace, providing a quick and efficient solution to keep infrastructure operational after an accident.
Standards and regulations
Fuse poles are subject to strict safety and performance standards, such as ISO 12767 or STRMTG regulations. Link to the official website
