Simeprovi - Spanish Association of Steel Road Restraint Systems Manufacturers

Product characteristics

The components of the steel safety barriers are manufactured from hot rolled steel coil, by a cold rolling process followed by hot dip galvanization in order to guarantee their protection against corrosion.

One of the main advantages of the steel barriers compared with other road restraint systems is its capability of adaptation to any section of the road where it is going to be installed. The components of the barrier allow it to adopt different configurations, depending on the type of elements that are used and the way they are combined.

The main characteristics of the system are reduction of the severity of the accidents, lowest cost and highest profitability.

Reduction of the severity of the accidentes

Steel barriers are aimed to reduce the severity of the accidents caused when a vehicle leaves the carriageway in an uncontrolled manner. As a consequence they provide:
  • Decrease of the number of deaths.
  • Mitigation of the injuries.
  • Limitation of the material damages caused to the vehicle and to third parts, with considerable savings in compensations due to accidents.

When an accident of the mentioned characteristics occurs, its consequences are limited to slight damages to the barrier, minimizing the damages to the vehicle and its occupants.

This is achieved by means of the controlled absorption of the impact energy, due to the deformability of the system, which results in:
  • Guaranteed containment: protects from impacts against obstacles, falling from slopes and invasions of close carriageways.
  • Smooth deceleration: avoids violent shakings to the occupants, which could cause severe injuries.
  • Optimal redirection: corrects the trajectory of the vehicle, avoiding rebounds and possible hazards to other users.

The main concern of the manufacturers of steel safety barriers is to get safer roads for all the users, including the most vulnerable ones.

Accordingly, they work in the design and standardization of systems which improve the performance of the barrier in case of impacts of motorcyclists.

Lowest cost

The cost of the steel safety barrier is less than 1% of the overall cost of the infrastructure. Building 100 km of a road without any protection has the same cost than building 99 km protected with this system.

¿What is preferible? The answer is obvious if we consider that the reduced investment in steel safety barriers that must be undertaken is remarkably lower than the extremely high social cost of the accidents caused by road exits.

In addition, the steel safety barriers are between twice and three times more economic than any other alternative system.

In the same way that we would not buy a car without safety belt in order to save money, we must not ignore in our roads the steel safety barriers.

Highest profitability

According to the US Federal Highway Administration (FHWA), safety barriers have a Cost/Benefit rate between 700% and 1400%.

Several studies stablish their period of amortization in less than 8 months, taking into account in one hand the cost of the system, and in the other hand the savings in social costs caused by the accidents.

The use of galvanized steel, as well as the strict quality control procedure which is applied to the materials and the production process, ensure a long durability to the steel safety barriers.
