Precast concrete products for road use - precast guardrail foundation

Precast concrete products for road use - precast guardrail foundation

Excellent workability and outstanding in reducing construction time.

When installing guardrails using conventional methods, issues arise such as the tensile stress of the vertical wall exceeding the allowable value and instability against overturning. As countermeasures for conventional methods, increasing the thickness of the members or adding reinforcement for stress, and widening the base plate for overturning are some of the solutions. To address these issues, we have developed an independent protective fence foundation called "Precast Guardrail Foundation."
