The main differences between metal fence and metal fence are as follows:

一、原材料1、 Raw materials

金属护栏网的原材料是低碳钢丝，一般是从3.0-6.0mm，是用盘条经过处理而成的；金属栅栏的原材料是热镀锌方管，一般是从16*16mm-100*100mm，厚度从0.8mm-3.0mm。

The raw material of metal guardrail is low-carbon steel wire, generally from 3.0-6.0mm, which is processed with wire rod; The raw material of metal fence is hot-dip galvanized square pipe, generally from 16 * 16mm to 100 * 100mm, and the thickness is from 0.8mm to 3.0mm.

二、做工2、 Workmanship

金属护栏网的做工过程是先把低碳钢丝校直截断，然后进行焊接成网片，有需要再进行焊接上边框；金属栅栏的做工过程是 先截断热镀锌方管，竖管然后开始冲孔，再进行冲压枪头，横梁先冲竖管大小的方孔，然后冲穿防盗螺丝的圆孔。

The working process of metal guardrail is to straighten and cut the low-carbon steel wire first, then weld it into mesh, and then weld the upper frame if necessary; The working process of the metal fence is to cut off the hot-dip galvanized square pipe first, then punch the vertical pipe, and then punch the gun head. The cross beam first punches the square hole the size of the vertical pipe, and then punches through the round hole of the anti-theft screw.

三、表面处理3、 Surface treatment

金属护栏网的表面处理有三种：热浸塑、静电喷涂、镀锌，其中镀锌又分为两种：电镀锌和热镀锌；金属栅栏的表面处理只 有一种：静电喷涂，因原材料已是热镀锌方管，所以不用再进行热镀锌处理。

There are three kinds of surface treatment of metal guardrail: hot dip plastic, electrostatic spraying and galvanizing, of which galvanizing is divided into two kinds: electro galvanizing and hot galvanizing; There is only one kind of surface treatment for metal fence: electrostatic spraying. Because the raw material is hot-dip galvanized square pipe, there is no need to carry out hot-dip galvanized treatment.

四、安装方式4、 Installation mode

金属护栏网的安装方式是把网片和立柱连接起来就可以；金属栅栏则是需要把竖管和横梁进行组装成型，还要用到几种铁艺 栅栏配件。

The installation method of metal guardrail is to connect the mesh with the column; The metal fence needs to assemble the riser and beam, and several iron fence accessories are also used.

如何区分护栏网质量的好坏？

How to distinguish the quality of guardrail?

护栏网质量好的通常使用纯料进行加工，成本要高一些。

The guardrail with good quality is usually processed with pure materials, and the cost is higher.

1、观察。通过表面塑粉颜色和平整程度的观察可以看到两种不同的现象：护栏网差的表面没有光泽，颜色暗淡，用手触摸如橡皮条；护栏好的表面光滑平整，颜色鲜艳动人，而且硬度比较好。

1. Observation. Through the observation of the color and flatness of the plastic powder on the surface, we can see two different phenomena: the poor surface of the guardrail has no luster, the color is dim, and it is like a rubber strip when touched by hand; The surface of the guardrail is smooth and flat, the color is bright and moving, and the hardness is relatively good.

2、测量。质量好的护栏网一般都按照规定的尺寸做，偏差较小，质量较重；质量差的护栏网一般都要缺斤短两有一定的偏差，质量较轻。

2. Measurement. The guardrail with good quality is generally made according to the specified size, with small deviation and heavy quality; The guardrail with poor quality is generally short of weight, with certain deviation and light quality.

3、触摸。用手感触其涂层表面看是否光滑细腻，用指甲按压看其硬度。比较硬的是质量好的护栏网。

3. Touch. Touch the coating surface with your hand to see if it is smooth and delicate, and press it with your fingernail to see its hardness. The harder one is the high-quality guardrail.
