Road Safety Barrier Application
a. To provide steel highway guardrail protection for motor vehicles against dangerous road areas such as steep slopes, high embankments, obscure curves/bends and sharp corners.
b. To absorb the kinetic energies from sudden impact collisions to minimize damage to the vehicle and injury to the passenger.
c. To act as a directional steel highway guardrail for drivers to be aware of the correct driving direction.
d. To act as a median barrier to avoid head-on collision.
Road Safety Barrier Advantage
a. Can ensure minimum damage to the vehicle and its occupants.
b.Repairs are quick ensuring that complete road safety is maintained along the entire length of guardrail.
c. Can prevent the vehicle from skidding back onto the carriageway by controlling exit angles through gradual deceleration and effective redirection of the vehicle back on to the road
d. All components are galvanized as a countermeasure against the elements for a longer service life.
e. Ideal replacement for traditional metal Roadway Guardrails.
f. OEM or ODM service offered
g. Precision machining and Extensive exporting experience

- Q: What is the standard height of highway guardrail design?
- The main consideration of the height of guardrail is the density of people and the terrain along it. 6 specifications for the use of cold-formed equilateral channel steel are provided for different force conditions, while other appropriate cross section steel is also available under the condition of strength and stability. From the main force direction of the channel column, the choice of specifications should make the core of the Y-Y axis (Iy) larger channel steel. The effective height of the national JTJ074-94 fence standard ranges from 1.6~1.8m, and this range of values takes into account the adult height to prevent crossing as the main design goal. It is observed that if people want to enter the highway, they usually destroy the guardrail, and the damage position is below 1.2m. Set up a high fence, although it can better prevent people from crossing, but it can not prevent people from entering the highway. What can really regulate people's behavior is legal awareness and social civilization. With the development of society and the improvement of people's legal consciousness, the number of people who violate traffic laws is bound to decline. Britain and other developed countries highway double ring fence design height is about 1.3 meters. Therefore, the fence should not be set too high, it is recommended in the general area, fence exposed height in the 1.2m-1.5m can be, the special areas in 1.6m is appropriate. This height of people is not easy to cross, but also saves investment. How much is the spacing between the posts of the guardrail net; because the height of the fence post is lowered, it is suggested that the column spacing should be 4m, and that it should be set at 201 5m per kilometre;
- Q: Is the grade B wave beam guardrail only installed at the corner?
- Loss of round column. Some sections of the soil soft, no compaction, into the round column is easy to lose. What's more, a bid section loses more than 1000 round columns. Even if these round columns are not missing. Can you meet the requirements of collision avoidance? The problem of lost column is actually the quality of construction.
- Q: What does waveform guardrail "Gr-A-4E" mean?
- Double wave beam guardrail, length 4320mm, width 310mm, wave height 85mm, plate thickness: 3mm, 4mm;Round column: specifications 140mm length, according to requirements, usually 2 meters, 2.15 meters, wall thickness 4/4.5MM; theoretical weight: 140mm 15.04kg/m. Phi
- Q: What is a highway guardrail drilling machine? What's the difference between it and highway guardrail and pile driver?
- In addition to its function and barrier, pile driver has some differences, there are some differences in appearance, more than a drill. In addition, the general foreign trade is the same, and the model classification is also synchronized with the guardrail piling machine. It is also divided into two types: ordinary vehicle and loading type. You can get to know the relevant equipment manufacturer.
- Q: Whether or not the guardrail end of the highway needs to be put into anti-collision barrels
- A crash bucket is installed at the end of the end to play a role in improving the warning effect. This is permitted by law, but not by specification!
- Q: Can a barrier block be used in the central divider and combination guardrail?
- Structural design of reinforced concrete central anticollision guardrailFourStructure design of anti dazzle board (1)FiveStructure design of anti dazzle board (two)SixStandard section, wave beam, steel guardrail, installation sectionSevenFlat and vertical layout of wave beam steel guardrail (no barrier block)EightFlat and vertical layout of wave beam steel guardrail (with anti blocking block)NineDesign of reinforced concrete bridge guardrail
- Q: Construction plan of plastic steel guardrail
- To ensure the quality of contract project completed on schedule, I carefully read the prequalification documents, according to the company intends to invest the mechanical equipment and construction technology; owners' requirements on the construction technology, quality, construction period; hydrology, geology, meteorological conditions and construction sites; the actual progress of the road subgrade, after careful research. The development of the following preliminary design of construction organization:
- Q: What are the penalties for damaging highway and traffic safety facilities?
- road lightingRoad lighting is mainly to ensure the safety and smooth traffic at night, and can be divided into continuous lighting, local lighting and tunnel lighting. Lighting conditions have a great influence on road traffic safety, and the sight guidance sign is usually arranged along both sides of the lane. It has the purpose of express the road alignment and induce the driver's sight. A reflective line of sight guidance is provided for the road section which is necessary to be led by sight at night.
- Q: What are the types of traffic barrier and the size and requirements of each classification?
- Some of the middle of the fence without vertical interval or vertical interval is too large, pedestrians can easily drill the fence, there are security risks; some barriers, intensity difference, human hand can remove isolated joints, easily damaged, useless; some rail welding point, not the bottom surface anticorrosion treatment, surface paint or plastic dipping treatment low, easy to rust, corrosion resistance, short service life.
- Q: What is the price of the insulated barrier in the middle of the road?
- The utility model relates to a zinc steel traffic barrier rail, which is a bread and oval galvanized steel pipe. The middle vertical rod is composed of a plum blossom tube, and a semicircular reflecting film is arranged in the center
