More traffic safety through crash barriers

Drivers are familiar with the crash barriers of motorways, bridges and public roads. But the crash barrier, often also called protective barrier, has a wider range of applications - not only in road construction. It is useful wherever road safety requires protection of the car against impacts from outside the roadway. Another important area of application is impact protection in factory traffic, public or private roads. Therefore, manufacturers of crash barriers also address the private sector with their products.

The different types of road crash barrier

The road crash barrier consists of posts that are connected to each other by a plank or several planks and thus form a guidance or restraint system. Today they are mostly made of steel, which is protected against corrosion by hot-dip galvanizing. However, there are also crash barriers made of aluminium, plastic or wood. Concrete crash barriers can also be found on motorways. However, steel has the advantage that it can absorb greater forces through deformation and does not break so easily. In principle there are several profiles for steel crash barriers. The first profile was developed in the USA in 1933. This A-profile has an undulating cross-section. The later developed B-profile, on the other hand, has an angular cross-section. Both profiles are approved for public transport in Germany. Safety-Rail and Super-Rail are also available as special shapes. These two particularly stable designs are specially designed for the restraint of trucks. Guardrails with underride protection are used to protect motorcyclists and other two-wheelers. However, not every manufacturer offers all types of crash barriers.

Where are crash barriers used?

Apart from public transport on roads, motorways, bridges, etc., the system of bollards and crash barriers is often used in the following areas, for example:

• Facade protection - in delivery traffic, the restraint system protects the facade against collisions with trucks.
• Parking garages and car parks - the guardrail provides the vehicle with both an optical line and a fall protection i parking garage. As collision protection for traffic, the steel crash barrier prevents collisions with technical equipment when entering and exiting.
• Plant protection - the plant is protected from traffic by the enclosure with crash barriers.
• Plant traffic - steel crash barriers prevent collisions between machines and forklift trucks, for example.

What you can expect from a good manufacturer

If required, the manufacturer offers an expert, free initial consultation. He can develop a guardrail system for the customer that is tailored to his specific situation and needs. In addition to supplying the appropriate posts, planks and connection technology, he also assembles the system. This should be possible promptly. In the event of any damage to the crash barriers, the manufacturer can quickly supply spare parts and, if necessary, also install them. A recommended manufacturer has more than one type of guardrail in its range and also supplies installation material and other accessories for the guardrails. Of course all products offered should comply with European standards.
