Cast aluminum road stud
There are two types of cast aluminum and cast aluminum shells. All-cast aluminum means that the shell is made of metal and has a relatively high compressive strength. It is generally used at double yellow lines and is generally called all-aluminum road studs. Cast aluminum shell means that the shell is cast aluminum and the inside is filled. The cost of such a road stud is lower than that of full cast aluminum, but at the same time the compressive strength is not so high. It is generally called cast aluminum road stud or cast aluminum filled road stud. .
Plastic road studs
There are also two types of plastic and plastic shells. All-plastic means that the shell is made of plastic injection molding, and the material may be ABS, AS+glass fiber, etc., with high compressive strength. It is generally called all-plastic road stud. The plastic shell means that the shell is made of plastic and the interior is filled. The cost of such a road stud is lower than that of all plastic, but at the same time the compressive strength is not so high. It is generally called a plastic road stud or a plastic-filled road stud.
