Usually, double line markings are used on more spacious roads. It is relatively simple to spray two parallel lines with cold jet marking machine. But many construction teams prefer hot melt road marking machines to draw Double Lines.
The disadvantage of using a hot-melt road marking machine to draw double lines is complicated construction and low efficiency, and the advantage is that the service life is much longer and the cost is much lower.
Our special "double line hopper" can draw two parallel hot melt marking at the same time, Double line forming at once.
