Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.

The custom application of hexagonal guardrail network plays a very important role in the channel slope protection work. According to the performance of the network, it can firmly grasp the soil so that it will not be lost, so the customized slope protection effect of hexagonal guardrail network is very significant, but also because of this advantage, it is widely used in such as channel protection, river bank protection, landslide protection. The custom structure of hexagonal guardrail is tightly combined, the appearance is not concave and convex, and it has satisfactory anti-corrosion, anti-oxygen and other capabilities. Construction without a lot of manpower and material resources, can be in the field of actual operation.
