Warehouse Line Marking: The Types and Why They are Important

Line marking is very important for any warehouse in order to manage the traffic. It can be used as an alternative for the signage and various other warning devices.

Before line marking tape or paint, the area should be completely cleaned in advance of application, using concrete degreaser. To avoid accidental contact, cordon off the locations where the floor line marking will be done.
