FAQs on metal crash barriers, types, and advantages

Metal crash barriers play an important role in roadway and highway  safety. They are designed to protect vehicles from accidents caused by collisions with roadside obstacles such as trees, bridges, and other structures. Made of steel, metal crash barriers are anchored to the ground with posts. They absorb the impact of the accident and help to redirect the vehicle away. If you are looking for metal crash barriers for your next project, here are some FAQs and their answers on metal crash barriers, types, and advantages: 

Question 1: What are the different types of crash barriers?

There are two types of crash barriers:

• W-beam barriers: These barriers are made of two steel plates bent into a "W" shape. These barriers are relatively inexpensive and easy to install so they can be found on many roads.

• Thrie-beam barriers offer additional protection as they have three steel plates bent into a "U" shape. This increased strength and durability mean they are best suited to areas with high traffic.

Question 2: What are the advantages of metal crash barriers over concrete ones?

Some of the advantages of metal crash barriers over concrete ones are::

• Durability: Metal crash barriers are an ideal solution for roadways, as they provide a strong and durable barrier that can effectively absorb the impact of a collision. They can withstand a wide range of weather conditions and impacts. They can last for many years without showing any signs of wear and tear. Concrete barriers often crack or chip over time.

• Flexibility:  Metal crash barriers have more flexibility than concrete barriers. They are designed to bend and redirect a vehicle, whereas concrete barriers are designed to stop a vehicle completely. This means that metal crash barriers can help reduce the severity of accidents

• Ease of installation: The installation of metal crash barriers is relatively easy in comparison to concrete crash barriers. 

• Recyclability: Metal crash barriers are recyclable, which makes them a more environmentally friendly option than concrete barriers. This means they do not end up in the landfill when they are no longer needed.

• Cost-effectiveness: Most metal crash barriers are inexpensive and easy to maintain, making them a perfect cost-effective solution for several roadways.

Question 3: How are metal crash barriers maintained? 

Metal crash barriers require less maintenance when compared to other road safety barriers. They are made up of strong steel that can withstand a collision. 

Question 4: How are metal crash barriers maintained?

Although metal crash barriers are low-maintenance, they  need to be checked from time to time. Here some common maintenance practices: 

• Painting: Metal crash barriers should be painted every 5 to 8 years.

• Inspection: Metal crash barriers must be inspected every 6 to 12 months to check for signs of corrosion, damage, or other problems.

• Tightening of nuts and bolts: Check them regularly and tighten them if they are loose to ensure that the crash barrier stays in place.
