In today's society, the construction and improvement of highway safety facilities has been widely concerned, among which the highway guardrail network as an important part, the choice of its connection mode is very important to ensure road safety. The main function of highway guardrail network is to provide physical isolation, prevent vehicles from accidentally driving out of the lane, and also reduce the severity of collision accidents to a certain extent. Therefore, the connection method of highway guardrail network not only needs to ensure the stability and durability of the structure, but also easy to install and maintain.

At present, the most common connection method of highway guardrail network is card assembly. This connection method is widely used because of its simplicity and firmness. The card assembly refers to the guardrail mesh and the column are tightly fixed together through the special card, which is not only fast to install, but also has high connection strength, which can effectively resist the external impact force, thus ensuring the overall stability and protection effect of the highway guardrail mesh.

When selecting the splice material, high-quality steel plates are usually used as raw materials. These plates are cut into small squares of a specified size, such as 500*500mm, and then precise holes are made in these small squares. The position and size of the openings are carefully designed to ensure that the card can be passed through and secured smoothly. Next, the perforated steel plates are welded to the posts and borders of the highway fence. In the welding process, the operator needs to ensure the uniform distribution of welding points to avoid the occurrence of welding leakage. After the welding is completed, it is also necessary to polish the welding joint to eliminate solder marks and ensure the overall appearance of the highway guardrail.

Although card assembly is the most popular connection method at present, there are other connection technologies on the market, such as bolt connection, rivet connection, etc. Each of these connections has its own characteristics, but when it comes to choosing, consumers will often decide the most suitable connection based on their own needs and budgets.

In short, the connection mode of highway guardrail network has a direct impact on its safety protection effect and service life. As a simple and firm connection method, card assembly has become the mainstream choice in the market. At the same time, when consumers buy highway guardrail products, they are also paying more and more attention to the installation convenience and aesthetics of products, which also prompts manufacturers to continuously optimize product design to meet the needs of the market.
