FAQ

What is the difference between DX51D and DX52D galvanized steel?

Both are grades under EN 10346, but DX52D offers improved ductility and is more suitable for severe forming operations compared to DX51D, which is designed for normal forming. The choice depends on the specific forming requirements of your application, such as when manufacturing complex deep drawn components.

What does the “Z100” designation mean in DX51D Z100 zinc coating?

The “Z100” refers to the total zinc coating weight on both surfaces of the steel sheet. Specifically, DX51D Z100 means the coil has a minimum total coating mass of 100 grams per square meter (e.g., 50g/m² per side). This is a standard coating class that provides a good balance of corrosion protection and cost for many applications.

Can you supply DX51D galvanized steel coil with a painted finish?

Yes, absolutely. Our factory can further process DX51D GI coils into pre-painted galvanized steel (PPGI) by applying color coatings on the galvanized surface. This provides enhanced aesthetics and additional corrosion resistance, making it ideal for architectural building panels and premium appliance exteriors.

What is your packaging for export to ensure the coils don’t rust during sea shipment?

We use robust, weather-resistant packaging to protect the coils. Each coil is wrapped with multiple layers of waterproof paper and a final outer cover of steel wrapper or plastic film. They are then securely fixed on wooden pallets or in steel cradles to prevent movement during transit. This method is standard for protecting galvanized steel coil for export and has proven effective for shipments worldwide.
