Shallow soil coverage allows for the installation of short and safe protective fences! Achieving a shortened construction period.

We would like to introduce our "Flexible R Intersection" continuous foundation that we handle. By increasing the foundation cross-section (width), we ensure safety with a short extension. We reinforce the support column installation hole and ensure safety with a 250mm embedment depth. The easy construction method, which only requires upper and lower combinations and bolt (M27) fastening, achieves a reduction in construction time. 【Features】 ■ Ensures safety with a short extension ■ Allows for the installation of protective fences in areas with shallow buried objects ■ Easy construction method ■ Achieves a reduction in construction time ■ Consideration for aesthetics *For more details, please refer to the PDF materials or feel free to contact us.
