Regardless of the type of rockfall protection net, we achieve reinforcement with flexible adaptability.
The Keiwan Coil Net Method is a reinforcement technique for existing rockfall protection nets. It effectively utilizes existing posts and wire nets without removal, allowing for reinforcement and repair while also providing impact absorption capabilities tailored to the specific object. By maximizing the characteristics of the coil-type net, it achieves a high energy absorption capacity with a capture performance of 150 kJ. It is also treated for rust prevention, ensuring excellent durability. Additionally, in the event of damage during maintenance, repairs can be made by replacing only some components. 【Features】 ○ Mitigates the impact of falling rocks, reinforcing the protection net for enhanced safety ○ Easy and safe installation with a short construction period ○ Significantly reduces traffic restrictions ○ Excellent cost performance ○ NETIS registration number KT-140046-A For more details, please contact us or download the catalog.
