“Korea’s first wireless traffic light pole is created
with an octagonal cross member structure.”
The first wireless traffic light pole in Korea with an octagonal cross member structure
With no messenger wire, the product gives an excellent clean urban beauty effect to the city.
It is manufactured using technology first developed in Korea, involving calculations of the wind load for optimal structure and the application of the patented tubular reinforcement structure, resulting in a more secure, robust, and safe structure than those of existing traffic light poles. It is mainly used for new installations and replacing installed products in innovative cities, urban development areas, and local governments.
조가선을 사용하지 않는 개선형구조
Advantages of improved traffic light poles
Korea’s first wire-free traffic light poles
(one-way, two-way, road name sign integrated type,
and CCTV cross member) perfectly address the weaknesses of existing traffic light poles. They can be
maintained conveniently and help manage road traffic while improving the city’s aesthetics.

A simple method of joining the cross members without using ribs
Made using innovative technology, they enhance the wind pressure safety of the entire post as a result of structural analysis conducted by the Korea Testing Laboratory (KTL). By reducing harmful gases (carbon dioxide) generated in the manufacturing process (welding) and producing efficient products, we provide solutions that help promote a clean urban environment.

평철 리브방식은 우천 시 또는 눈이 쌓여 상부에 물이 고여 부식이 진행되며,
용접량이 많고 작업공정이 길어집니다.
원형리브방식은 물이나 눈이 쌓아지 않아 부식을 원천봉쇄하며
용접공정의 최소화 및 힘의 분산으로 인한 구조적인 안전성을 확보하였습니다.
- 가로부착재의 환경부식성을 평가하기 위하여 염수분무시험
(ASTM B-117; ISO 9227)을 수행하였으며 염수에 500시간 노출한 후 인장강도를 측정.
- 염수분무시험을 위해서는 해수와 가장 유사하도록 pH 6.5~7.2의 염화나트륨
염수용액을 제조하여 시험 규격인 ASTM B117-18 조건에 맞추어 측정함.
- 인장강도 변화율 –5.8%
