Everything You Wanted to Know About Guard Rails

Busy Indian roads witness thousands of cars and other vehicles zooming through highways every day. Although the majority of us care about the quality of the highway or the velocity of traffic, all of us rarely notice one of the most important safety-related factors, which saves lives silently: guardrails. Also referred to as crash barriers or roadside barriers, guardrails are an important feature of contemporary road systems. And they are not only there to line our highways; they help to save thousands of lives by not allowing cars to get off the road on the way to crashing or losing control.

What Are Guard Rails?

Guard Rail are safety barrier systems placed on the median or side of highways, bridges, and steep slopes to prevent vehicles from exiting from the roadway. The majority of highway guard rails are made of high-strength galvanized steel, which also provides impact energy-absorbing functions and proper rerouting of vehicles back onto the roadway.

Knowing the Types of Guard Rails

Various types of guardrails are as follows:

W-Beam Guard Rails

The most widespread one, W-beam guardrails, is of a corrugated structure that is usually wavy and widely distributed to spread the impact energy effectively. They are situated on the highways, motorways and industrial areas. Some of the features of these highway guardrails are:

Key features:

• Corrosion resistant
• Simple to assemble and to change damaged parts.
• Good at preventing medium-impact collisions.

Thrie-Beam Guard Rails

Thrie-beam has greater strength and breadth compared with W-beams. They are extra stiff and strong with their triple-wave design, making them suitable for high-speed or heavy-traffic areas that may be national highways and bridge approaches.

Key features:

• Increased impact resistance and holding capacity.
• Less danger of the car tipping over.
• IRC:119 and AASHTO M180 compliant.

Cable and Median Barriers

Cable barriers and median guard rails are applied in the urban regions or divided highways in order to separate the opposing traffic lanes. Such systems reduce head-on collisions and prevent cars from crossing to the other lanes.

Key features:

• Flexible design
• affordable installation process
• Excellent for low-to-medium traffic areas.

How do Guard Rails Work?

Guardrails are not meant to stop a vehicle abruptly. Instead, they are engineered to control and redirect the motion of a vehicle in a collision. 

This energy absorption and redirection process benefits:

• Reduce the severity of crashes
• Prevent the vehicles from overturning or leaving the roadway
• Reduce damage to the vehicle and its occupants

The deflection distance (how far the rail deflects when it is impacted) is a calculated amount; it is designed so that while the barrier deflects back enough to absorb the forces, it does not deflect back too far so that the vehicle can leave the roadway.

Advantages of Installing Guard Rails

Let us now look at some of the benefits of installing guardrails. 

Enhanced Safety

The primary safety feature of guardrails on highways is that they provide a barrier against major accidents. This could happen in a situation where a driver was momentarily distracted, leading to an unintended consequence, or it began to rain and the roadway became slick or tired experienced a blowout.

Durability 

Modern guardrails use hot-dip galvanisation to bolster their resistance against rust, moisture, and environmental factors. This coating allows the guardrail to serve its purpose in service for many decades with little maintenance.

Being Cost-Effective Road Protection

The cost of the potential for accident damage, as well as the lives lost in accidents, is a good value for guardrail protection for both public and private infrastructure projects.

Compliance with Safety Standards

Guard rails in India, manufactured by verified companies, like Treadsafe Steel, comply with safety standards outlined under MoRTH, IRC, and AASHTO – a safeguard for operational reliability on Indian roads.

What are the Applications of guardrails?

Guardrails are utilised in many locations, including:

• National and state highway systems
• Bridges and overpasses
• Mountain and hilly roads
• Industrial setups
• Airport perimeters
• Parking lots and distribution centers

Installation and Maintenance

Proper installation is critical to the performance of guardrails. General methods of installation are:

• Site survey and methodology – determining the type and location of the barrier. 
• Foundation preparation – setting the posts at consistent depths. 
• Beam installation – ensuring proper beam height and overlap to allow for continuous protection.
