Achieving a road environment without bumps or uneven surfaces!
The "GR-U" is made of ductile cast iron, the same material as manhole covers. Its load-bearing performance complies with T-25 based on the Road Bridge Design Guidelines, ensuring that it does not suffer from damage or deformation even in harsh road environments where large vehicles frequently pass, preventing any rattling. Additionally, the surface's anti-slip structure reduces the risk of slipping. 【Features】 ■ Stable drainage performance ■ Slip prevention ■ Prevention of entrapment ■ Clogging prevention ■ Prevention of rattling and scattering due to steep slope support structure, etc. *For more details, please download the PDF or contact us.
