For construction and industrial projects operating in harsh corrosive conditions — coastal solar farms, marine structures, chemical processing plants and heavy infrastructure — standard galvanized steel and even regular ZAM grades often cannot deliver the required service life. CNB New Material is proud to introduce our flagship heavy-duty product: ZM600 ultra-high coating Zn-Al-Mg steel.
Why ZM600 stands out
As one of the first manufacturers in China to achieve mass production of 600g/m² zinc-aluminum-magnesium coated steel, we have engineered this product for maximum durability in extreme environments:
- Industry-leading corrosion resistance: 8–12 times the corrosion protection of conventional Z275 galvanized steel. The unique alloy composition forms a dense, stable corrosion product layer at cut edges and damaged areas, delivering excellent self-healing performance.
- Proven mechanical performance: Available in grades DX51D–DX57D and S220GD–S550GD, with good formability for bending, stamping and roll forming operations.
- Full specification range: Thickness 0.3–8.0mm, width 900–1600mm, coil ID 508/610mm, coil weight 4–12mt. Custom sizes and surface treatments (passivated, oiled, anti-fingerprint) are available on request.
Ideal applications
ZM600 steel is purpose-built for the most demanding scenarios:
- Coastal and offshore photovoltaic support structures
- Marine engineering and port facilities
- Chemical equipment and storage tanks
- Highway guardrails and bridge components
- Agricultural facilities in high-humidity, high-salt regions
By extending service life and reducing maintenance cycles, ZM600 steel significantly lowers the total lifecycle cost of your projects.
Quality & documentation
Every order comes with complete mill test certificates (MTC), and third-party SGS inspection is available. We also provide full CBAM documentation for EU-bound shipments.
