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

一、原材料1、 Raw materials

金屬護欄網的原材料是低碳鋼絲，一般是從3.0-6.0mm，是用盤條經過處理而成的；金屬柵欄的原材料是熱鍍鋅方管，一般是從16*16mm-100*100mm，厚度從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

金屬護欄網的做工過程是先把低碳鋼絲校直截斷，然后進行焊接成網片，有需要再進行焊接上邊框；金屬柵欄的做工過程是 先截斷熱鍍鋅方管，豎管然后開始沖孔，再進行沖壓槍頭，橫梁先沖豎管大小的方孔，然后沖穿防盜螺絲的圓孔。

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、表面處理3、 Surface treatment

金屬護欄網的表面處理有三種：熱浸塑、靜電噴涂、鍍鋅，其中鍍鋅又分為兩種：電鍍鋅和熱鍍鋅；金屬柵欄的表面處理只 有一種：靜電噴涂，因原材料已是熱鍍鋅方管，所以不用再進行熱鍍鋅處理。

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、安裝方式4、 Installation mode

金屬護欄網的安裝方式是把網片和立柱連接起來就可以；金屬柵欄則是需要把豎管和橫梁進行組裝成型，還要用到幾種鐵藝 柵欄配件。

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.

如何區分護欄網質量的好壞？

How to distinguish the quality of guardrail?

護欄網質量好的通常使用純料進行加工，成本要高一些。

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

1、觀察。通過表面塑粉顏色和平整程度的觀察可以看到兩種不同的現象：護欄網差的表面沒有光澤，顏色暗淡，用手觸摸如橡皮條；護欄好的表面光滑平整，顏色鮮艷動人，而且硬度比較好。

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、測量。質量好的護欄網一般都按照規定的尺寸做，偏差較小，質量較重；質量差的護欄網一般都要缺斤短兩有一定的偏差，質量較輕。

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、觸摸。用手感觸其涂層表面看是否光滑細膩，用指甲按壓看其硬度。比較硬的是質量好的護欄網。

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.
