1.Principle of wave guardrail

(1)Corrugated beam guardrail is the main form of semi-rigid guardrail. It is a continuous structure with corrugated steel guardrail panels spliced together and supported by columns.

(2)It uses the physical deformation of the soil foundation, columns and beams to absorb the energy generated by the collision, and forces the out-of-control vehicle to change its driving direction, return to the normal road driving direction, and prevent the vehicle from running off the road. This plays a role in protecting vehicles and passengers and reducing accident losses.

(3)The corrugated beam guardrail is both rigid and soft, has a strong ability to absorb collision energy, has a good driving sight inducing function, and can be coordinated with the road alignment and various facilities. Its appearance is beautiful and elegant, and it can be installed and used on small-radius curves. The connection is simple and convenient, and the damaged parts are easy to replace.

2.Classification

(1)According to the installation location, it can be divided into roadside guardrails and central divider guardrails.

(2)According to the anti-collision level, it can generally be divided into Class A and Class B. Class A guardrails are reinforced types and are suitable for use on particularly dangerous sections of roadside, while Class B guardrails are used on dedicated highways.

Commonly used roadside corrugated beam guardrails can be divided into five levels: B, A, SB, SA, and SS according to the anti-collision level. Highway anti-collision guardrails are typical cold-formed steel products.

(3)According to the surface treatment, it is divided into two types: hot-dip galvanized corrugated guardrail and galvanized spray-coated guardrail.

The corrugated guardrail with plastic spraying has better anti-corrosion performance. It is hot-dip galvanized first and then sprayed with plastic to achieve double anti-corrosion effect and beautify the environment.

(4)According to color classification, it can be divided into galvanized silver white, plastic spray green, white, blue, etc. Customized colors are acceptable.

(3)Column cap: thickness 2/3mm, hole spacing 100/150mm, diameter 114/140mm.

(4)Anti-blocking block: 196*178*200mm, thickness is divided into 3mm/4mm/4.25mm/4.5mm. Bracket: 300mm long, 70mm wide, 4mm/4.5mm thick.

(5)Bolts: M16*170 / M16*150 / M16*50 / M16*42 / M16*35

4.Advantages of Manufacturing Steel Highway Guardrail System

  There are many types of guardrail system production in the market today. However, only systems that made of steel can make the safest guardrail with minimal impact.

Complete protection of the vehicle and automobile
Minimize injuries to the passengers
Easy installation
High resistance and strength
Easy maintenance and repair

5.Summarize

  The corrugated guardrail is a combined corrugated plate movable steel guardrail used at the opening of the central separation zone of the highway. The guardrail consists of two corrugated steel guardrail panels and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail panels. During normal operation of the highway, the guardrail can be easily inserted into the pre-set plug-in hole at the opening using plug-in and pull-out columns to play the role of isolation and protection. At the same time, it echoes the guardrail belt on the outside of the highway, making it uniform and beautiful.

  When a vehicle collides with it, because the corrugated steel guardrail has good crash resistance and energy absorption, it is not easily destroyed, but at the same time it can play a very good role in protecting the vehicle and the passengers.

The corrugated guardrail also has a sight-inducing function and a better sight-guiding function, which helps to improve driving safety. When road maintenance or other special circumstances require temporary lane closure, corrugated guardrails can conveniently handle openings to facilitate the smooth passage of vehicles.

  To sum up, the corrugated guardrail is a traffic safety facility that combines practicality and aesthetics, and plays an important role in ensuring the safety and order of highway traffic.
