What types of safety barriers are there?

Below is a list of the various types of safety barrier:

Traffic barriers

Traffic barriers are used to segregate lanes of traffic and create clear vehicle routes. There are many different types of traffic barrier – from portable temporary barriers to fixed barriers. These can be found both within facilities and on roads.

Crash barriers

When people refer to ‘crash barriers’ this is usually in relation to the types of barriers that line motorways and busy roads. Often made from stainless steel or another type of metal, these barriers cover long distances and provide rigid protection against stray vehicles.

Pedestrian barriers

Pedestrian barriers refer to the types of barriers that usually define pedestrian routes and walkways through busy facilities and areas with increased vehicle activity. Not only do they provide protection for people walking alongside them, but they provide additional support for pedestrians usually in the form of a handrail.

Guardrails

There is no difference between a guardrail and a safety barrier. Guardrails is simply another term used to describe safety barriers, most commonly in the USA.

What are safety barriers made of?

There are different materials that are often used to make safety barriers. The most common types are concrete, steel and plastic.

What is the difference between concrete, steel and plastic safety barriers?

Although concrete, steel and plastic safety barriers perform the same fundamental role, the levels and types of protection they provide can vary with each material. 

Concrete safety barriers

Concrete barriers can be installed in specific places and are sometimes cast in place. They are secured to the floor with cement. Sometimes concrete barriers are reinforced with steel or metal to help provide more robust protection from crashes.

Steel barriers

Safety barriers made from galvanised steel are incredibly common – especially at roadsides. These often take the form of long stretches of barrier that segregate traffic and provide protection from vehicles moving in different directions.

Plastic and polymer barriers

Plastic safety barriers are often referred to as 'polymer safety barriers' This refers to the type of material they are made from. Some polymer barriers are used as temporary protection while others are more robust and designed for long-term industrial protection. These polymer safety barriers are designed to defend against collisions and then return to their original shape so they can be used again.
