DX52D+ZF Galvannealed Steel Coil
Product Description
DX52D+ZF Galvannealed Steel Coil is a zinc-iron alloy coated steel product designed for drawing applications and general cold forming. Manufactured through continuous hot-dip galvanizing followed by an alloying heat treatment, DX52D+ZF features a metallurgically bonded zinc-iron coating that supports subsequent painting, resistance spot welding, and metal fabrication.
Also referenced as DC52D+ZF in some material specifications and procurement inquiries, this steel grade is suitable for manufacturers requiring improved forming performance compared with general forming grades. DC52D+ZF combines a drawing-quality steel substrate with a galvannealed coating, making it a practical material option for automotive components, appliance panels, and formed sheet metal parts.
For buyers comparing DX51D+ZF and DC52D+ZF, the main consideration is the substrate's forming capability. DX52D+ZF is intended for drawing applications where greater deformation capability is required. Rosen supplies DX52D+ZF Galvannealed Steel Coil with different coating specifications and dimensions, subject to production availability.

Product Features
DX52D+ZF features a ZF coating formed through hot-dip galvanizing and subsequent alloying heat treatment. Iron diffuses into the zinc layer to create a zinc-iron alloy coating with a characteristic matte gray appearance.
Compared with general forming grades such as DX51D+ZF, DX52D+ZF is designed for drawing applications. Its mechanical properties support forming operations that require greater deformation capability.
The galvannealed surface provides favorable characteristics for subsequent painting and powder coating. Appropriate cleaning and surface pretreatment should be selected according to the final coating system.
The zinc-iron alloy coating is suitable for resistance spot welding. Welding current, electrode pressure, welding time, and electrode maintenance should be adjusted according to the actual coating specification and production conditions.
The zinc-containing alloy coating provides sacrificial corrosion protection to the steel substrate. Coating mass, surface treatment, and additional painting systems should be considered together to meet the corrosion protection requirements of different applications.
Multiple Steel Grades and Coating Options
Rosen supplies galvannealed steel in different forming grades, including DX51D+ZF, DX52D+ZF, DX53D+ZF, and DX54D+ZF. Customers can select suitable material specifications according to their forming and manufacturing requirements.
Steel Coil and Sheet Processing
Rosen supports steel coil supply as well as slitting and cut-to-length processing to accommodate different production requirements.
Specification-Based Material Selection
Our team can review steel grade, coating weight, thickness, width, surface treatment, and intended forming process to help customers identify suitable material specifications.
Flexible Supply Arrangements
Both stock supply and customized production arrangements are available. Delivery schedules depend on material specifications, stock status, and order quantity.
DX52D identifies a drawing-quality steel grade under EN 10346, while ZF indicates a zinc-iron alloy coating. DX52D+ZF is therefore a drawing-quality steel substrate with a galvannealed coating.
DX52D+ZF is designed for drawing applications and offers greater forming capability than general forming grade DX51D+ZF. For demanding deep-drawing operations, higher-formability grades such as DX53D+ZF or DX54D+ZF may be considered.
Both grades use zinc-iron alloy coatings, but their substrate forming classifications differ. DX51D is intended for general cold forming, whereas DX52D is designed for drawing applications. The appropriate grade depends on component geometry and forming requirements.
Rosen's published galvannealed steel range includes double-sided coating weights of 80–120 g/m². The specific coating weight should be confirmed according to the application and order requirements.
Yes. DX52D+ZF can be considered for automotive components, appliance panels, and other formed metal parts requiring drawing performance, a zinc-iron alloy coating, and subsequent surface finishing.
Please provide the required steel grade, coating weight, thickness, width, coil inner diameter, surface treatment, quantity, and intended application. This information helps Rosen review material availability and prepare an accurate quotation.
