This diameter of this series glass bead is two or three times bigger than regular beads. The surface part beyond paints is higher than regular beads; hence the reflectivity of road marking has been increased, especially in rainy, foggy areas.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.

2. Long bar fixing method: By means of the pressing force of the screw, the long bar with groove is fixed on the drum along the axial direction of the wire rope.
3, plate fixing method: using a pressure plate and screw fixation rope, simple, reliable, easy to observe and check is the most common form of fixed, the disadvantage of this method is that a relatively large space, and therefore, can not be used in a multilayer Winding. In terms of safety, the number of platens is at least two.
In order to ensure reliable fixing end of the rope, reduces the force of the pressure plate or wedge, when the means to extract the lower limit position, fixed out of the loop of wire rope on the drum in addition, it will also be retained 1.5-3 ring safety circuits.
The diameter is 850-1400mm (20-14mesh) with ≥80% of roundness. The special coating on the surface of glass bead can improve the adhesion between paint and glass beads, thus the longevity can be increased.
How to properly fix the wire rope on the reel
1, wedge fixed method: This method is commonly used in small diameter wire rope, do not need to use bolts, suitable for multi-layer winding reel.
