wire mesh Fence acceptance test item

The frame fence mesh is a flexible assembly product widely used in China's highways, railways, highways, etc.; it can be used as a mesh wall or as a temporary isolation network, which can be realized by different column fixing methods. .

 

The following are three items for the inspection and acceptance of the fence.

First, the fence network specification test

 

1, the size of the mesh. Mesh is also a factor affecting the quality of the fence, and it also affects the use of the product. This item can only be done with a ruler measurement.

 

2, the diameter of the wire. Wire diameter is a crucial factor affecting the quality of the fence network, and the price is different. Therefore, this item should be tested and the inspection tool uses a micrometer.

 

3. External dimensions. Everyone knows that only a steel tape can be used.

 

4. Other projects. There are also fences, columns, struts, etc. of the fence, which, regardless of the requirements in the drawings, have an impact on the quality of the fence.

 

Second, the fence surface detection

 

1. Whether there are any defects on the surface. Observe the phenomenon of broken wire, broken hole, and exposed bottom of the surface.

 

2. Coating process. Look at the coating is not what you want, the coating process is electroplated zinc, hot-dip galvanizing, spray, dip, spray paint and so on.

 

3. Coating color. Observe that the color of the coating is not correct, whether it is doped with other colors, the color is not bright, and there is no hair.

 

Third, the fence material testing

 

1, other materials size. Other materials involved are the size and thickness of the ear, the thickness and size of the fitting, and the like.

 

2, coating thickness. This item generally does not cause problems, mainly related to equipment and settings, but occasionally the coating becomes thicker or thinner or uneven.

 

3, the size of the inner wire. This is a problem that is easy to ignore, but it definitely has an impact on the price and quality of the fence. It is also a must for manufacturers to reduce costs.
