In the purchase of municipal fence profiles fence, you will find that some sections are after phosphate treatment. So, what is the 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 before painting base, improve the adhesion and corrosion resistance of the film layer; cold working process from metal friction lubrication. Usually after phosphate treatment may enhance the profile between the coating layer (such as paints and coatings) and workpiece binding yard barrier, and improve its decoration and surface coating of corrosion resistance, but also enhance its resistance Corrosion protective. Contrast profiles including color, thickness, texture, and its interface will face: generally inferior profiles, it's back to the filler material or excessive use, rough surface, color gray rail fence, crisp texture difference, a relatively short time on It will fade aging. The high-profile, its color more positive, soft, and smooth surface, good texture, strong toughness fence, bright colors not faded. Yard barrier super hardness steel installation, cut pile post links embedded, no welding, anti-theft screws overall interpretation. Firm does not break, not easy to destroy, railing spacing options, high density, can not drill more. In the rainy season to maintain their special.
