The so-called fixed type, that is, the net guardrail is produced in one piece during the production process. From the production of different parts to the assembly of the parts, the products are all integrated, only through the corresponding Equipment technology, network guardrails can be applied to practice as a whole product. It can also be said that this kind of net guardrail is seeking permanent.
It is not necessary to replace the net body and the column permanently. It is assumed that the net guardrail is damaged and the overall replacement is performed. Such a net guardrail is superior in the quality of the product, and it is not easy to appear that the net body and the column are respectively used for a long time, and have a long service life.
However, although the permanent net guardrail has a relatively good degree of stability, this kind of interest is actually a shortcoming. Since the overall characteristics are now available after the end of the device, the entire network guardrail has to be replaced in the event of damage to the mesh.
