What is EN 10305-4 E235+N phosphate tubes?

Phosphate-coated EN 10305-4 E235+N tubes are engineered to offer enhanced corrosion resistance. The application of a phosphate coating forms a protective barrier on the tube surface, effectively preventing the onset of rust and other corrosion types. This safeguard guarantees the longevity and reliability of your hydraulic steel tubes, even when exposed to demanding environmental conditions.
