Fence profile constitutes a very flexible assembly of products, the industry has been widely used. So does anyone know its process, what does? Let Xiaobian tell you it. 1 steel layer (Base steel): base rails, hardness value 159DPN. 2, zinc steel alloy layer (Zeta layer): the closest base layer of dense alloy layer structure is complicated, strong corrosion resistance. 3, sub-lead layer: significant monoclinic system columnar structure, Fe content of 6% non-toxic street rails, and corrosion resistance. 4, the pure zinc layer: dense hexagonal, deformation processing is not easily broken. 5, high temperature curing layer: excellent corrosion resistance and anti-impact performance, with excellent resistance to UV, antioxidant and surface self-cleaning properties. In the purchase of fence sections, you will find that some sections are after phosphate treatment. So community fence, what is phosphate treatment, why should its phosphate processing it? Phosphate is a chemical and electrochemical reaction to form a phosphate chemical conversion coating process, the phosphate conversion coating formed called phosphate coating. The main purpose of the phosphate is to: provide protection to the base metal, to a certain extent, prevent metal corrosion; used in high-grade primer before painting the fence, to improve adhesion and corrosion resistance of the film layer; the metal from the cold process friction lubrication. Usually after phosphate treatment profiles can enhance the coating layer (such as paints and coatings) and the binding force between the workpiece and improves its decoration and surface coating of corrosion resistance, but also enhance its corrosion-resistant protective.
