What is spring band type traffic sign?
As a result of spring band adoption, the sign plate rotates and minimizes loads transferred to the pole when any wind loads over the specified value are applied. This is to protect facilities from damages. According to the result of wind tunnel test by the Korea Aerospace Research Institute, the rotation of sign plate is definitely affected by the clearance between the central axis of horizontal pole and the spot where the sign plate is installed. For spring band type traffic sign, the spot where the sign plate rotates by 40degrees when the wind load 30m/s applied is informed in the manufacturing process.

Characteristics

• The advance notice of spring band installation site makes the related works easy and simple.
• Damages caused by typhoon and vehicle crash and budgets for the restoration can be reduced.
• Additional repair is not required since the sign plate rotates and returns to the original position even after vehicle crash.
