【Green Laser】Sharp linear pattern! Capable of projecting over long distances! 【NETIS Registered_G-Sculight Method】

【NETIS Registration Number HK-240021-VE】*Recommended Technology Certification by the Ministry of Land, Infrastructure, Transport and Tourism for Fiscal Year 2028 Composed of a special filter that aligns the projection focus with the height and distance of the light source, battery, and projector! This method is a technology that projects a pattern of light onto the road surface, instantly visualizing the designated position of lane markings. It can be applied to sites requiring straight line marking work, such as road construction lane markings. Since marking work is unnecessary, improvements in economy, process, safety, workability, and labor-saving are expected. 【Application Conditions】 ■ Natural Conditions: No restrictions due to wind ■ Site Conditions - Usable in environments with brightness below 200 lux (from evening to early morning) ■ Regions where technology can be provided: No regional restrictions 【Application Range】 ■ Applicable Range: Curves with a distance of less than 100m between the start and end points (BC to EC) on straight and curved roads ■ Particularly effective application range - Roads with long straight sections - Environments with low illumination, such as nighttime construction or inside tunnels, where it is difficult to see marking lines made with chalk lines ■ Inapplicable Range: Curves with a distance of 100m or more between the start and end points (BC to EC) *Please feel free to contact us.
