Environmentally friendly rockfall protection and avalanche prevention combined fence "Triangle Fence"
All materials are recyclable! A groundbreaking protective fence that is environmentally friendly and resistant to falling rocks and avalanches.
The "Triangular Fence" is a protective fence that effectively works against both falling rocks and avalanches, serving as a dual-purpose rockfall protection and avalanche prevention barrier. The entire fence absorbs the energy of falling rocks, and the large deflection of the net helps to suppress the impact. There are support posts on the valley side of the fence, and the net is bent towards the valley side, allowing it to capture falling rocks without letting them escape. Additionally, there is no need to create a concrete foundation, and significant excavation is not required. It can be installed with minimal tree cutting, contributing to CO2 reduction. 【Features】 ■ The entire protective fence absorbs the energy of falling rocks ■ The large deflection of the net suppresses impact force ■ Captures falling rocks without letting them escape ■ Prevents falling rocks from slipping out from under the fence ■ Remains stable even when rockfall, avalanche, or snow pressure acts diagonally on the fence surface due to its triangular truss structure *For more details, please refer to the PDF document or feel free to contact us.

Company information
Until now, we have been cutting down trees on the slopes, excavating the ground to install concrete foundations, and then placing avalanche prevention shelves and rockfall protection shelves on top. However, the avalanche prevention shelves are ineffective against rockfalls, and the rockfall protection shelves are powerless against avalanches. The "triangular fence" developed and sold by our company effectively functions against both avalanches and rockfalls, and it does not require any excavation of the ground or concrete work, which could cause secondary disasters. It can be easily constructed using only lightweight materials, making it an environmentally friendly construction method suitable for the 21st century that does not compromise the landscape.
