Metal steel Wire mesh fence highway guardrail,highway guard rail price
It uses soil base guardrail panels, column, beam deformation to absorb impact energy, and forcing runaway vehicle to change direction, to return to the normal direction of travel of the vehicle out of the road to prevent the outside, in order to protect the vehicle and passengers and reduce the losses caused by the accident.
Color: galvanized silver, spray green, white, blue and so on.
Press waveform guardrail waveform can be divided into two-and three-wave-shaped guardrail.
Surface treatment is divided into two types according to spray hot dip galvanized and galvanized guardrail waveform.
By setting location can be divided into roadside guardrail and the guardrail median strip.
Waveform guardrail highway crash level can be divided according to class A and S-Class. S-class guardrail belongs enhanced for particularly dangerous sections of road side use, A grade for private roads. Common roadside beam guardrail crash level can be divided by B, A, SB, SA, SS five.
1.Highway guardrail waveform is the main form of semi-steel guardrail, which is a corrugated steel Fence panels to each other by stitching columns supporting a continuous structure.
2.Which uses soil base, column, beam deformation to absorb impact energy, and forcing runaway vehicle to change direction, to return to the normal direction of travel of the vehicle out of the road to prevent the outside, in order to protect the vehicle and passengers and reduce the losses caused by the accident.
3.Waveform highway guardrail steel soft phase and, with a strong ability to absorb collision energy, has good sight inducing function, can be coordinated with the road alignment, beautiful appearance, can be used on small radius corners, damaged place easy to replace.
Waveform guardrail is the main form, which is a kind of corrugated steel guardrail plates are spliced continuous structure supported by the main column. Beam guardrail steel soft phase and, with a strong ability to absorb collision energy, has good sight inducing function, can be coordinated with the road alignment, beautiful appearance, can be used on small radius corners, damaged place easily replaced. Combination beam guardrail can be used in a narrow median strip. The way the vehicle (bridge), the sector may cause serious consequences, you can choose to strengthen beam guardrail.
Waveform guardrail utility model involves a highway median strip opening with combination wave plate movable steelguardrail, the guardrail between the two pieces of the corrugated steel fence panels and two fixed clip to put two columns constituted two columns fixed interposed between two sheets of corrugated steel guardrail panels. When the road normal operation, the use of plug guardrail post can be easily inserted into the opening of the pre-set plug hole, played the role of isolation and protection, while outside on the road and guardrail with echoes, uniform, beautiful package. When their vehicle collision, since the corrugated steel guardrail boards have good crashworthiness and energy absorption effect, not easily been destroyed, while at the same vehicles and Division staff play a very good protection. When a road maintenance or other reasons need and pass, you can easily put the groups pull out guardrail
post openings removed to open up channels for easy passage of vehicles.
