Rigid protective fence Precast Guard Fence (PGF)
This is a concrete rigid guardrail that complies with the "Installation Standards for Guardrails" set by the Japan Road Association (Public Corporation). 【Features】 ○ Because prestressing is applied - During a vehicle collision, the blocks undergo slight deformation in an arc shape, absorbing the impact and then returning to their original shape, functioning as an elastic concrete structure. ○ Because it is a product from a JIS-certified factory - The concrete is dense and has excellent water tightness and durability. ○ It can be installed in a short period and can be used immediately - The processes of transporting blocks, installation, block joint construction, and PC tensioning can be carried out simply and quickly. ○ It can be installed even in areas with a small curve radius - Such areas are prone to accidents, making a safe guardrail necessary. In our installation records, we have installed it in a high-speed road ramp section with a radius of 50 meters. ○ We are also skilled in short section installations ○ It can be easily laid even if there is a height difference between the upper and lower lanes - In curved sections of the road, there may be a height difference in the central divider between the upper and lower lanes. By using a single slope cross-section type, it is easy to accommodate the height difference. ○ There are structures that can be temporarily installed for traffic regulation and can be permanently installed in the future as well. *For more details, please contact us.
