Different Highway Crash Barriers:Guard Beams & Steel Wire Cable Guardrail
Highway Guardrail System are used to provide good safe guard for highway and expressway.Here we introduce two forms of crash barriers,wave beam guardrails and steel wore cable guardrail.
Beam guardrail is consisted of two beams and posts fixed between them.Beam barrier is the main form of the semi-steel railings,which is a continuous structure that is stitched with a corrugated steel guardrail and supported by a pillar.
It absorbs the collision energy through the deformation of the soil base, the post and the beam, and forces the uncontrolled vehicle to change direction and returns to the normal direction to prevent the vehicle from rushing out of the road,so as to protect the vehicle and passengers, and reduce the loss caused by the accident. Beam guardrail features strong ability to absorb the impact of energy, and good transport induced vision function. It can be coordinated with the road line shape,and can be used for roads with small radius curves.
The classification of the guardrail beams: Guardrail Beam is generally classified by location and crash level. According to the location,it can be divided into roadside guardrail and central divider guardrail. According to the crash level, it can be divided into A and S level. S-class rail is reinforced to be suitable for especially dangerous use of the roadsides, while A-level for the special roads.
The material for the guardrail beams are high quality steel plates with anti-corrosion treatment.The manufacturing process includes high-quality steel plate with pickling treatment, stamping into a double wave or three wave plate, after that is hot galvanized or hot galvanized plastic spraying treatment.Often used as railing, decoration, protection and other facilities for industrial, agricultural, municipal, transportation and other industries.
The other highway barrier is Steel Wire Cable Guardrail,also called cable crash barrier normally.There are generally two specifications for wire cable guardrail: 5 layer cable guardrail and 6 layer cable guardrail. Cable barrier are all adopted hot galvanized treatment, and some with PVC dipping treatment, the two anti-corrosion guardrail measurements both make the steel wire cable have very good performance, while the dipping treatment cable guardrail has a better visual effect. According to the engineering requirements to choose from.
Steel Wire Cable Guardrail components: cable guardrail post, cable, cable guardrail middle post, spacer and so on. For the cable guardrail, the post mainly play the role of supporting the cable. The cable guardrail is supported at both ends of the post, and the cable need to be tighten up so as to ensure the effective protection of the whole guardrail.Main application: highways, railways and protective zone on the both sides of bridges;airport, port, wharf;mountain and tourist attractions road safety protection.
Compared with the traditional guardrail barrier, cable guardrail has better unobstructed view of the horizon for visitors to enjoy the natural landscape. The additional advantages includes preventing secondary injuries and reducing the safety accident of drivers and passengers; Better view of road surface, reducing the driver’s eye fatigue.
