The difference between metal guardrail and metal fence

1. Raw materials
The raw materials of metal guardrail net are low-carbon steel wire, generally from 3.0-6.0mm, which is processed by wire rod; the raw materials of metal fence are hot-dip galvanized square tubes, generally from 16*16mm-100*100mm, and the thickness ranges from 0.8mm-3.0mm.

2. Workmanship
The workmanship process of metal guardrail net is to straighten and cut the low-carbon steel wire first, and then weld it into mesh, and then weld the upper frame if necessary; the workmanship process of metal fence is to cut the hot-dip galvanized square tube first, then punch the vertical tube, and then punch the gun head, and punch the square hole of the vertical tube size on the crossbeam first, and then punch the round hole of the anti-theft screw.
3. Surface treatment

There are three types of surface treatment for metal guardrail nets: hot dip plastic, electrostatic spraying, and galvanizing. Among them, galvanizing is divided into two types: electrogalvanizing and hot dip galvanizing; there is only one type of surface treatment for metal fences: electrostatic spraying. Since the raw materials are hot dip galvanized square tubes, hot dip galvanizing is not required.

4. Installation method

The installation method of metal guardrail nets is to connect the mesh and the column; metal fences need to assemble the vertical pipes and beams, and also use several iron fence accessories.
