Road Isolation Guardrail Barrier

Road isolation guardrail barrier of the standard name is guardrail barrier System; Highway Guardrail is a metal beam passive barrier system mostly processed from corruguated steel plates 10 gauge and 12 gauge, through flattening, punching, hot dipped galvanizing and shearing processes, into solid metal beams with symmetrical shapes of waves, with a radiums ranging from 5’ to 60’, specially installed along the highway road side, bridges, median openings and viaducts for safety and reducing the potential danger of vehicle crashing.

Benefits:
1, no painting and maintenance, not old, relieve fatigue and trouble of maintenance, integrated into a low.
2, making installation quick and easy, using patented bearing rub connection or proprietary connection accessories for installation, greatly improving the efficiency of the installation.
3, many different specifications, different styles as you choose, both European and American style and contemporary fashion, noble and modern aesthetic.
4, safety, environmental protection, human (animal) harmless, even if inadvertently touched the fence will not be as hurt as steel, iron fence.
5, guardrail lumen lined with galvanized steel or aluminum alloy are enhanced, has sufficient strength and impact resistance, so that both the strength of the steel guardrail PVC and PVC aesthetics.
6, using special formula and special UV absorbers, no fading, no yellow, no peeling, no cracking, no blistering, no insects, life of up to 30 years.
Widely used:
Urban roads, decoration real estate, development zones, residential areas, gardens and landscaping all types of enterprises and safety engineering.

Our products range from the guard rail highway barriers, sound barriers and fences to the various accessories for installation of barriers and fences. We use choic cold processing steel strip to make quality guardrail panels for our customers, going through flattening, punching, galvanizing or plastic coating, fabricating and shearing process. The guardrails can be traditional beam type solid guardrail panels or economic cable guardrails.The steel guardrail panels are made of corrugated plates in symmetrical shapes of waves. It is either concave (bowing away from the traffic lane) or convex (bowing towards the traffic lane).The guardrail beams we supply are 10 gauge and 12 gauge materials, ranging from 5’ to 60’ radius. Made from strip steel coils, the guardrail panels have a normal thickness of 2mm to 10mm. Metal fittings we supply include brackets, beam posts, columns and terminals for completing a full guardrail barrier system.

How to choose straight W beam or Curved Beam used for your uses?
The straight W-beam guardrail can be lined up for transitioning smoothly and is suitable to the curves with a radius greater than 45m. For the radius less than 45m, the pre-curved W-beam guardrail product exploits its advantages to a full.

W beam guard railings can be used in expressway and highways to absorb maximum energy of the impact force when collision occures and reduce harms to cars and people. It can also protect the vehicles against skidding off roads, especially mountain roads and bridges and prevent the pedestrians from the danger of walking across highways.
