Surface Treatment of Galvanized Steel: Phosphating vs. Passivation

The core objective of surface treatment for galvanized steel is to “play to its strengths while mitigating its weaknesses”—preserving its excellent rust prevention (red rust resistance) capabilities while overcoming drawbacks such as susceptibility to white rust and poor coating adhesion. Currently, Wanzhi Group’s primary surface treatments for galvanized steel include passivation, phosphating, coating, sealing, and

Steel and Steel Classification

Steel is a metallic material primarily composed of iron (Fe) with a carbon content below 2.11% (C<2.11%). Its carbon content typically ranges from 0.02% to 2.11%. Mechanical properties, machinability, and corrosion resistance can be enhanced by adding alloying elements such as manganese, silicon, chromium, and nickel. Steel can be classified based on chemical composition, smelting

Rust on PPGI Steel and Premium PPGI Steel

Causes and Solutions for Rust on PPGI Steel Paint Film Surface

One common issue with outdoor PPGI material is surface rusting. Some coatings labeled as rust-resistant for 10-25 years develop rust spots within less than a year. What causes this phenomenon? And how can we resolve or prevent it? Causes of Rust Formation on PPGI Steel Coatings Production-Related Factors Uneven or insufficient zinc coating thickness: The
