Hot dip galvanized eyebolts have high strength and corrosion resistance. In recent years, they have become the preferred bolts for power towers, signal towers and highway guardrails. Today, Xiao Bian introduces some knowledge about hot-dip galvanized eyebolts.

With the development of technology, hot-dip galvanized eyebolts have been widely used. Compared with stainless steel bolts, the cost is much lower and the strength is much higher. It can be said that hot-dip galvanized bolts have replaced stainless steel bolts in outdoor installation.

1、 Advantages of hot-dip galvanized eyebolts

1. Low production cost.

2. High production efficiency and fast delivery.

3. It is widely used.

4. It has strong corrosion resistance.

2、 Production process of hot-dip galvanized eyebolt

The production process of hot-dip galvanized eyebolts is complex. First, degrease and derust the bolts. When the bolt presents a pollution-free and wet surface, it shall be immediately immersed in the zinc bath to form a zinc coating on the bolt surface. It should be noted that the zinc solution in the plating solution must be preheated in advance.

3、 Applicable scope of hot-dip galvanized eyebolt

The coating of hot-dip galvanized eyebolts is very thick, generally 30-60 microns. The coating has high corrosion resistance and is suitable for long-term outdoor rust prevention projects, such as road fences, power towers, large fasteners, etc. In addition, the old iron water pipes will be connected by hot-dip galvanized bolts.

4、 Specification for hot-dip galvanized eyebolt construction

Including ordinary bolts and bolts with reamed holes, which belong to non-standard parts. According to the shape of the head, there are many types of hot-dip galvanized bolts, such as hexagon head, round head, square head and countersunk head. Both ends of the hot-dip galvanized bolt have threads, which can be used together with the nut. It is mainly used to fix tubular objects (such as water pipes) or sheet objects (such as automobile leaf springs).

The material property of Grade A and Grade B hot-dip galvanized bolts is 8.8, which are processed by lathe and have the characteristics of smooth surface and stable size. The production and installation of these two bolts are complex and expensive, so people rarely use them. The material property of Grade C hot-dip galvanized bolt is 4.6 or 4.8, and the material is unprocessed round steel. These bolts are characterized by large deformation, simple installation and low production cost, and are mainly used for tensile connection or temporary fixation.
