GR-C-4E highway waveform guardrail

Description :

  GR-C-4E waveform guardrail is a semi-rigid anti-collision facility designed specifically for rural roads and low-grade roads, mainly to solve the safety problem of vehicles losing control and rushing out of the roadbed or colliding with roadside obstacles. This type of guardrail absorbs collision energy through the deformation of corrugated steel plates, forcing out of control vehicles to change direction and return to normal driving direction, preventing vehicles from rushing out of the road. As a typical representative of anti-collision waveform guardrails for rural roads, GR-C-4E is suitable for sections with low traffic volume and relatively low vehicle speed. It can effectively protect the safety of drivers and passengers and reduce vehicle damage, and is a core component of rural road safety protection engineering.

  The main material of the waveform guardrail is Q235 carbon structural steel, which has good plasticity, toughness, and welding performance, ensuring that the guardrail can undergo moderate deformation without fracture when impacted. The GR-C-4E model usually corresponds to double wave waveform beam and slab, with a standard plate thickness of 3.0mm or 4.0mm, a wave height of 85mm, and a wave spacing of 310mm, which complies with transportation industry standards such as JT/T 281. Surface anti-corrosion treatment usually adopts hot-dip galvanizing or spray coating process, and the thickness of the galvanized layer needs to meet the specification requirements to adapt to the long-term outdoor environment of wind, sun, and rain, ensuring the corrosion resistance and service life of the anti-collision waveform guardrail on rural roads under complex climatic conditions.

  In the selection and application, GR-C-4E waveform guardrail is particularly suitable for scenarios such as rural roads, county and township roads, and scenic area roads that require a medium to low level of collision resistance. Compared with models such as Gr-A-4E used on high-grade highways, the column spacing and plate strength of GR-C-4E are more suitable for low-speed driving environments, and the cost is more economical. When purchasing, it is necessary to clearly distinguish the applicable roadside conditions. If there are significant differences or high-risk factors in the road section, it is necessary to evaluate whether to upgrade the anti-collision level. For rural roads with many bends or poor visibility, it is recommended to use contour markers to enhance visibility at night and in adverse weather conditions, ensuring effective protection.

  When installing the GR-C-4E waveform guardrail, it is necessary to strictly control the depth and verticality of the columns to ensure the smooth alignment of the guardrail and the fastening of the splicing bolts in place. In daily maintenance, it is necessary to regularly check whether the guardrail board has serious deformation, rust, or loose connections, especially after a collision accident, damaged parts need to be replaced in a timely manner to restore protective capabilities. For areas where the surface coating peels off, timely anti-corrosion repairs should be carried out to prevent the substrate from rusting and expanding. Keeping the area around the guardrail unobstructed by weeds not only helps to extend the service life of the anti-collision waveform guardrail on rural roads, but also ensures the effective functioning of the obstacle warning function.
