Manufacturing and Anti-Corrosion Process

Our welding procedures are approved by major classification societies. The surface treatment reaches Sa2.5 blasting standard, followed by an anti-corrosion coating system consisting of zinc-rich epoxy primer, epoxy micaceous iron oxide intermediate coating, and high-build aliphatic polyurethane topcoat, with a total dry film thickness of no less than 250 μm. This coating system provides 5–10 years of corrosion protection.

For selected products, hot-dip galvanizing (HDG) is also available, improving corrosion resistance by up to 300% and offering more comprehensive protection for harsh marine environments.
