Highway double wave guardrail is a kind of semi-steel structural facilities for highway collision prevention and isolation, almost every highway in China has installed wave guardrail plate, it is a highway foundation protection products, mainly made of high-quality steel plate, and anti-corrosion treatment to improve its durability and safety. This guardrail has the advantages of good impact resistance, low cost, long life, high safety performance and green environmental protection.
Product characteristics
1. Good anti-corrosion performance: The use of galvanizing or spraying process, effectively prevent rust and corrosion, extend the service life.
2. Anti-aging: The material selection of high-quality steel, with good anti-aging performance, to maintain long-term stability.
3. Beautiful and generous: the design is simple and generous, and can be coordinated with various environments.
4. Easy and quick installation: the column spacing is usually 4 meters, and the reinforced type can be adjusted to 2 meters, which is easy to install and maintain quickly.
5. The energy absorption effect is significant: by absorbing energy during the collision, the vehicle reduces the harm to the driver and passengers.

Material and specification
1.guardrail plate: the section is W shape, the specification is generally 4320×310×85×3/4mm, the thickness is 3mm or 4mm.
2. Column: steel pipe column or flange column, the length has a variety of choices, such as 1000mm, 1200mm, 1500mm and so on.
3.Baffle blocks and fasteners: Accessories such as baffle blocks and bolts can be configured according to specific requirements.
Application scenario
Highway double-wave guardrail is mainly used for the isolation and protection of highway lanes, especially the use of combined corrugated plate movable steel guardrail at the opening of the central divider to ensure driving safety. In addition, it is also suitable for fencing, decoration and protection facilities in industrial, agricultural, municipal, transportation and other industries.
Safety performance
The research shows that the double-wave guardrail has a good energy absorption and buffering effect in the process of car collision, and the maximum impact kinetic energy absorption can reach 906kJ, so as to effectively protect the safety of vehicles and passengers. For special sections such as curves, ramps and overpasses, double-wave guardrail with encrypted columns is often used to enhance its protective ability.
In short, highway double-wave guardrail with its excellent performance and reliable protection ability, has played an important role in ensuring traffic safety. Whether it is a new road or an old road renovation project, it is one of the indispensable important facilities.
