ロンタイ Company Profile

For 60 years with the greenery of this country, we will connect the green landscapes to the future.

Gentle green spreads across the slopes of the road, blending into the landscape. This green may be what is called "slope greening," which is planned and planted during road construction. Our work in slope greening aims to prevent slope collapse, protect people's lives and communities, and restore damaged ecosystems. With the belief of "green that protects people," Rontai is committed to greening efforts.

Business Activities

Manufacturing and sales of civil engineering greening materials and greening construction.

We have created a "Design and Evaluation Manual" that will help in the selection and evaluation of deer damage control measures!

  • PRODUCT

In recent years, following the implementation of slope greening work, we have received numerous inquiries regarding countermeasures due to the increase in damage caused by deer, such as feeding and trampling. A common concern among these inquiries is, "I don't know which method to choose!" With various countermeasure methods available, many people may find that the criteria for selecting them are not well established. In response, Rontai has created a "Design and Evaluation Manual" that aids in method selection based on our testing and performance data, as well as deer distribution maps. Additionally, we have included criteria and points for evaluating results after construction. We also offer free on-site surveys, so if you are struggling with wildlife damage countermeasures, please feel free to consult with us!
