Double wave guardrail plate specification

Double wave guardrail plate as an important highway collision prevention facilities, its specifications mainly include the following aspects:

View details

Length: Usually 4320mm.

Width: Generally 310mm.

Wave height: 85mm.

Plate thickness: there are two common specifications of 3mm and 4mm.

Engineering dosage and theoretical weight

In practical applications, understanding the engineering dosage of double-wave guardrail plate and its theoretical weight is crucial for budgeting and construction arrangements:

Laying distance of one ton double wave guardrail plate:

The 3mm thick guardrail plate can be spread 80 meters.

4mm thick guardrail plate can be spread 61 meters.

Theoretical weight:

The 3mm thick guardrail plate is about 49.16kg each.

The 4mm thick guardrail plate is about 65.55kg each.

Material and surface treatment

The double wave guardrail plate is mainly made of Q235 material, which has good tensile strength and corrosion resistance. Common surface treatment methods include:

Hot dip zinc: provides good anti-corrosion properties.

Galvanized + spray: not only has good anti-corrosion performance, but also provides a variety of color options, such as blue, green, white and yellow.

Column and connection method

The installation of double wave guardrail plate needs to be used with the column, and the common column types and specifications are as follows:

Round column:

There are 114mm and 140mm diameters.

The wall thickness of the tube is 4mm and 4.5mm.

Square column:

The side length is 130mm and the wall thickness is 6mm.

Column spacing: Generally divided into 2 meters spacing reinforced type and 4 meters spacing commonly used type.

Applications

The W-beam guard rail, a popular safety barrier, is extensively used in road infrastructure to enhance traffic safety. Its primary function is to prevent vehicles from leaving the roadway and to mitigate the severity of accidents. The W-beam design, characterized by its continuous wave-like shape, offers superior strength and energy absorption compared to other types of barriers.

Highways and Expressways: W-beam guard rails are commonly installed along highways, expressways, and arterial roads to protect vehicles from roadside hazards such as ditches, trees, or steep embankments. Their ability to deflect vehicles back into traffic lanes helps to reduce the likelihood of serious accidents.

Curves and Intersections: On sharp curves and near intersections, where the risk of vehicle deviation is higher, W-beam guard rails act as a critical safety feature, preventing vehicles from losing control and skidding off the road.

Bridges and Overpasses: W-beam barriers are often placed along bridges and overpasses, where the risk of falling off is more significant. They provide an essential safeguard to keep vehicles from veering off the edge in case of sudden steering adjustments or accidents.
