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

此种组装方式是将竖杆插入横杆，使用简介机械将其焊接在一起即可。

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

两类组装方式各有千秋，前者运输便利，费用较低，组装简单快捷，但是较易遭到损坏;后者坚固耐用，不易被损坏，但是组装时占用空间较大，费用偏高。因此，在选择组装方式时要看铁艺护栏安装环境的实际情况而决定。

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.组装式

2. Assembled

这种组装方式又分为四种：工字卡、钢簧卡、钢片卡、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：因为固定用的卡子为“工”字型而得名，作为一种外用卡子，组装后可以直观的看到。这是一种比较过时的固定方式，几年前使用较多，现在不多见了。

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 This is an outdated fixed method.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.

钢簧卡：钢丝制作而成的卡簧，是一种内用卡，铁艺护栏组装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.

钢片卡：用铆钉将钢网面固定在立柱上，然后再插入横杆，这样可以自行卡好。

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，组装时将塑料卡放入横杆，再将竖杆插入即可。这是一种新型的组装方式，既简单又快捷，现在使用比较多。

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.
