Precision carbon steel hydraulic tube is galvanized to improve corrosion resistance, wear resistance and extend service life. Galvanized Steel Tube ## Phosphated Steel Tubes Phosphating is the process of forming a phosphate film on the surface of steel tubes. Phosphating allows subsequent coatings (such as paint, coatings or anti-corrosion coatings) to adhere better to the surface of hydraulic steel tubing. Thereby enhancing the adhesion of the coating and improving the surface protection effect. It can also improve corrosion resistance.
