According to the material, it can be divided into [1] :
1. Cast aluminum road nails;
2. Plastic road nails;
3. Ceramic road nails;
4. Glass fairway nails;
5. Reflective beads (divided into 21 beads and 43 beads, which can be combined into cast aluminum and plastic nails).
According to the function, it can be divided into:
1. Ordinary road nails;
2. Solar road spikes,
3. Tunnel cable road nails;
4. Wireless road spikes.
According to the number of reflective surfaces, it can be divided into: single-sided road nails and double-sided road nails.
Generally, cast aluminum road nails, plastic road nails, ceramic road nails, and glass ball road nails are put into ordinary road nails:
1. Cast aluminum road nails
There are two types: fully cast aluminum and cast aluminum shell.
All-cast aluminum means that the shell is all made of metal, the compressive strength is relatively high, generally used in double yellow lines, generally called all-aluminum road nails. Cast aluminum shell means that the shell is cast aluminum, the interior is filler, such a road nail cost is lower than that of full cast aluminum, but at the same time the compressive strength is not so high, generally called cast aluminum road nails or cast aluminum filled road nails.
2. Plastic road studs
There are two types: all plastic and plastic shell.
All plastic means that the shell is all plastic injection molding, the material may be ABS, AS+ glass fiber, etc., high compressive strength, generally called all-plastic road nails, plastic shell means that the shell is plastic, the inside is filler, such road nails cost is lower than all plastic, but at the same time compressive strength is not so high, generally called plastic road nails or plastic filled road nails.
3. Ceramic road nails
The material is cement ceramics, round, early application is more, fragile during transportation, generally not recommended.
4. Glass fairway nails
The material is glass, which was used more in the early days, but more difficult in construction and installation, and now it is less used. It is generally not recommended.
5. Reflective bead nails
The reflectors are 21 or 43 high-brightness reflective beads. The manufacturer is represented by Schwarfas.
