Product core value: a revolutionary breakthrough of zinc-free flower coating

Smooth Surface Galvanized Steel is the benchmark product of the new generation of high-end anticorrosive steel. Through innovative process, we eliminate the zinc crystal on the surface of traditional galvanized sheet, create a smooth metal surface like a mirror, and set a new standard in the field of industrial anticorrosion, precision machining and high-end coating.

Why choose zinc-free flower design?

Zero visual interference: the surface texture without crystal particles perfectly fits the minimalist aesthetic needs of modern architecture.Coating revolution: The density of zinc layer is increased by 15%, providing "zero defect" substrate for color coating/fluorocarbon spraying, eliminating the problem of coating foaming and peeling.Process universality: compatible with laser cutting, deep stamping, high frequency welding and other advanced processing technology, breaking through the limitations of traditional galvanized sheet processing.

Whole process intelligent manufacturing system: closed loop from steelmaking to finished product quality

As a source plant with independent steelmaking capacity, we realize full link control from raw materials to finished products:

Production Stage	Technical Highlights
Raw Material Refining	Utilization of ultra-low carbon steel (C≤0.02%) smelting to ensure substrate ductility and weldability .
Galvanizing Process	Air knife precision control of zinc coating thickness (dual-side adjustable range: 60-275g/m²), with zinc purity ≥99.995% .
Surface Treatment	Optional chromate passivation or eco-friendly chromium-free passivation, compliant with RoHS directives .
Intelligent Slitting	Laser width measurement system achieves ±0.5mm cutting accuracy; coil weight tolerance ≤1% .

Global standard adaptation: seamless connection to the international market

"One Single Pass Global" solution:

European and American markets: meet ASTM A653/A653M (American standard) Grade G60-G300 zinc layer standardCommonwealth countries: meets BS EN 10346 DX51D+Z series specificationsEnvironmental protection certification: through the REACH regulation SVHC 239 test, support the export of EU environmental protection certification

Customization ability for special scenarios

Zinc aluminum magnesium coating (ZAM) enhanced version: corrosion resistance increased to the ordinary galvanized sheet 5-8 timesFingerprint resistant surface treatment: suitable for precision electronic equipment shell manufacturingLong service life: excellent quality, normal life can reach 20-25 yearsDifferentiated packaging scheme: moisture-proof paper + steel tape binding /PE film vacuum packaging is optional

Industry solutions: from infrastructure to high-end manufacturing
