Highway guardrails are essential safety features that protect motorists and help prevent severe accidents on roadways. They are designed to redirect vehicles that have left the roadway back onto the pavement or to prevent them from falling off bridges or other overpasses.Guardrails are typically made of steel or concrete and are installed along the side of roads and bridges. They are made up of vertical posts and horizontal rails that are connected by bolts or other fasteners. The posts are usually embedded in the ground or attached to bridges.

**Date:** March 7, 2025**Location:** National Highway Network, ChinaIn a significant move to enhance road safety, the Chinese Ministry of Transport has announced the installation of advanced highway guardrails across the national highway network. This initiative is part of a broader effort to reduce traffic accidents and improve driver safety on the country's extensive and heavily traveled roadways.The new guardrails, made from high-strength steel and designed to absorb impact energy more effectively, are expected to significantly decrease the severity of accidents.

Data from crash tests released by the University of Nebraska on Wednesday shows that electric vehicles, which typically weigh more than gasoline-powered cars due to the weight of batteries that are almost as much as a small gasoline car, can easily break through steel highway guardrails that are not designed to withstand the extra force, raising concerns about the nation's roadside safety system.Due to the weight of the battery, electric vehicles usually weigh 20% to 50% more than gasoline vehicles and have a lower center of gravity.

Based on the data from the US Department of Transportation, 30-40% of fatal accidents occur when vehicles leave the road. Another shocking statistic is that 30% of all cross-median collisions end in serious injury or fatality. These statistics have led to the increased implementation of anti-collision barriers to prevent vehicles from leaving the road or crashing into oncoming lanes. Concrete medians and metal guardrails save lives every year and make the roads safer.

Types of highway guardrailsCommon types of highway guardrails include:-corrugated guardrail: composed of interconnected corrugated plates and columns, which can prevent out-of-control vehicles from running off the road.-cable guardrail: composed of a set of cables and columns, which can effectively absorb collision energy and prevent out-of-control vehicles from running off the road.-concrete guardrail: a guardrail made of concrete that can provide higher protective performance and can be customized in shape and size as needed.-wire mesh guardrail: a guardrail made of wire mesh that can provid

According to the US Department of Transportation, 30-40% of fatal crashes occur when vehicles are run off the road. Another shocking statistic comes from 30% of all cross-median crashes ending in severe injury or fatality. These statistics have led to increased implementation of crash barriers to prevent vehicles from coming off the road or smashing into oncoming lanes.

In addition to highway guardrails, the following are some other measures to prevent car accidents:Traffic safety education: Strengthen traffic safety education for drivers and pedestrians to improve their awareness of traffic safety and awareness of compliance with traffic rules.Vehicle safety inspection: Regularly conduct safety inspections of vehicles to ensure the normal operation of various equipment and components of the vehicle, and reduce accidents caused by vehicle failures.Road design and maintenance: Reasonably design roads to ensure road safety and fluidity, and regularly maintain a

The transition section of the highway waveform guardrail plate is mainly used for connecting the transition and the connection of the subgrade wave beam guard board and the bridge concrete guardrail. So, how to handle the transition section of the general highway waveform guard board? A reasonable transition connection is not carried out between most of the highway waveform guardrail plate and the bridge concrete guardrail, so that the connection part of the two guardrail is hidden danger.

The main installation methods of highway guardrailsThe main installation methods of highway guardrails are as follows:Embedded installation: Embed the guardrail in the road base and fix it with concrete. This method is suitable for newly built roads.Flange installation: Install the flange plate of the guardrail in the reserved hole on the road and fix it with nuts. This method is suitable for existing roads.Driven installation: Drive the column of the guardrail directly into the road base and fix it with concrete.
