road guardrails cost per foot

how much does road guardrails cost per foot

road guardrails cost per foot fluctuates up and down. When choosing the road guardrails, the customer should take the quality as the premise under the condition of reasonable price.

Highway construction is increasing, waveform guardrail as a kind of semi-steel guardrail. It has been used more frequently in recent years. Why is it widely used as waveform guardrail of highway?

Highway corrugated guardrail is a structure consisting of guardrail columns fixed and corrugated guardrail panels spliced together.road guardrails cost per foot uses the deformation and tension of guardrail panels when vehicles collide to alleviate the impact force produced by collision and absorb collision energy. It has the function of guiding the driver's sight and increasing the aesthetic effect of the road.

On general highway, the length of corrugated guardrail is 4320MM, and the column is controlled at 4M intervals. But for dangerous sections,road guardrails cost per foot is necessary to install 4320MM reinforced corrugated steel guardrail with 2320MM length or 2M spacing between columns. The fixed device of reinforced corrugated steel guardrail is compact in structure, simple in installation and low in cost, which not only increases the speed.

road guardrails cost per foot the anti impact ability of the important powder box steel guardrail with corrugated beam on the highway can prevent the guardrail plate from being covered in this section, ensure the safety of the highway vehicles, reduce the installation of the opposite driving vehicles, and reduce the incidence of accidents.

road guardrails cost per foot can also be increased, the cost of using the heightening device is very low, and the construction is relatively simple, the impact on the normal traffic of vehicles is relatively small, and road guardrails cost per foot has no impact on the roadbed, shoulder and central partition belt. So now we use the waveform fence of highway as the protection device of highway.

At present, the protection of guardrail products is mainly divided into four categories: galvanized, aluminized, electrostatic spraying after galvanizing (aluminium), hot dipping after galvanizing (aluminium).

road guardrails cost per foot introduce

Guardrail is an important traffic safety facility along expressway, which plays an important role in road guardrails cost per foot protecting the safety of passengers and vehicles.

road guardrails cost per foot is also an important part of expressway maintenance and maintenance. The proportion of maintenance funds occupied in daily maintenance and maintenance of expressway is often high.

How to make full use of the limited maintenance funds and reduce the maintenance cost of the guardrail has always been a problem that every expressway operation and Management Department expects to solve, and the application of the technology of the rebuilding and reuse of the guardrail is a good choice to solve this problem. Next, we will explain the essentials and necessity of popularizing and applying the plastic spraying technology of guardrail panel mainly from the comparison of maintenance cost.

Because the guardrail belongs to the large-scale and long-term outdoor facilities, different protection systems must be selected according to different atmospheric environments to carry out the necessary metal anti-corrosion treatment.

In less polluted areas, protection by hot-dip galvanizing or electrostatic spraying can be used separately. In coastal cities or heavy industrial zones, especially in areas with acid rain, ordinary hot-dip galvanizing or electrostatic spraying single-coated fence panels may lose their effectiveness if they do not reach their service life, resulting in a significant increase in the maintenance cost of fence panels.

guardrail offset blocks

road guardrails cost per foot although the corrosion resistance of hot-dip aluminized guardrail is better than that of ordinary hot-dip galvanized guardrail, the cost comparison of its process, technology and environmental impact is much higher than that of hot-dip galvanized guardrail, so road guardrails cost per foot should not be popularized.
