Iron guardrail is widely used because of its beautiful appearance and elegant temperament. Whether in the courtyard wall of the community or the roadside of the expressway, you can see the figure of iron guardrail. Is it clear about the assembly method of iron guardrail? Choosing an appropriate installation method will help to improve the service time of iron guardrail. Let's have a look today. Generally, there are two assembly methods of iron guardrail, one is assembly type and the other is welding type.

1.焊接式

1. Welded

此種組裝方式是將豎桿插入橫桿，使用簡介機械將其焊接在一起即可。

This assembly method is to insert the vertical bar into the cross bar and weld it together with the machine.

兩類組裝方式各有千秋，前者運輸便利，費用較低，組裝簡單快捷，但是較易遭到損壞;后者堅固耐用，不易被損壞，但是組裝時占用空間較大，費用偏高。因此，在選擇組裝方式時要看鐵藝護欄安裝環境的實際情況而決定。

The former has convenient transportation, low cost, simple and fast assembly, but it is easy to be damaged; The latter is durable and not easy to be damaged, but it takes up a large space and costs a high price. Therefore, the selection of assembly mode depends on the actual situation of the installation environment of iron guardrail.

2.組裝式

2. Assembled

這種組裝方式又分為四種：工字卡、鋼簧卡、鋼片卡、塑料卡。

This assembly method is divided into four types: i-card, steel spring card, steel sheet card and plastic card.

工字卡：因為固定用的卡子為“工”字型而得名，作為一種外用卡子，組裝后可以直觀的看到。這是一種比較過時的固定方式，幾年前使用較多，現在不多見了。

I-card: it is named because the fixing clip is of "I" shape. As an external clip, it can be seen intuitively after assembly. This is an outdated fixed method. It was used more a few years ago, but now it is rare.

鋼簧卡：鋼絲制作而成的卡簧，是一種內用卡，鐵藝護欄組裝好后是看不到卡件的。

Steel spring clip: the clip made of steel wire is an internal clip. The clip can not be seen after the iron guardrail is assembled.

鋼片卡：用鉚釘將鋼網面固定在立柱上，然后再插入橫桿，這樣可以自行卡好。

Steel sheet clamp: fix the steel mesh surface on the column with rivets, and then insert the cross bar, so that it can be clamped by itself.

塑料卡：卡扣式塑料制作而成，組裝時將塑料卡放入橫桿，再將豎桿插入即可。這是一種新型的組裝方式，既簡單又快捷，現在使用比較多。

Plastic card: it is made of snap type plastic. When assembling, put the plastic card into the cross bar, and then insert the vertical bar. This is a new type of assembly method, which is simple and fast. Now it is used more.
