Highway guardrail application scenarios

Highways are used as anti-collision facilities, isolation facilities, etc., and the application scenarios are as follows:

Highway Guardrail Features

How to choose the right highway guardrail

1. Recommendations on the type of highway guardrail

• The anti-collision capability of w beam guardrail is relatively weak, and it is suitable for areas with low traffic volume and low speed, such as general highways and rural roads.
• Thrie beam guardrail has stronger anti-collision performance and is mainly used for high-grade highways such as expressways and first-class highways.

2. Recommendations on material selection

• Q235 has good strength and toughness, and high-speed guardrails usually use Q235 steel.
• Highway guardrails are exposed to the outdoors for a long time, and guardrails need to be treated for corrosion, so it is recommended to choose galvanized guardrails.

3. Recommendations for selection in different scenarios

• In sections where vehicles are prone to loss of control (curves, downhill sections), guardrails with higher anti-collision levels should be selected.
• Considering the type of vehicle, for roads where large trucks often travel, the anti-collision capability and strength of the guardrails also need to be improved accordingly.

Highway Guardrail Weight Calculation Formula

Formula for calculating the weight of corrugated highway guardrails

Weight = board length × board width × board thickness × steel density.

For example, the raw material width of the common two-wave guardrail is about 465mm, and the steel density is 7.85g/cm³. If the board thickness is 3mm and the length is 4.32m, its weight is (465-3)×3×0.00785×4.32≈47kg.

Formula for calculating the weight of Guard Rail Post

If the column is a round column, the calculation formula is weight = (aperture – wall thickness)×wall thickness×0.02466×length.

For example, the weight of a column with a diameter of 140mm, a wall thickness of 4.5mm, and a length of 1m is (140-4.5)×4.5×0.02466×1≈15.04kg.

Theoretical weight table

Product name	Specification	Theoretical weight
W Beam Guardrail	4320×310×85×3mm	49.16kg
	4320×310×85×4mm	65.55kg
Thrie Beam Guardrail	4320×506×85×4mm	102kg
Guard Rail Post	Diameter 114mm, wall thickness 4.5mm	12.16kg/m
	Diameter 140mm, wall thickness 4.5mm	15.06kg/m
