DX52D galvanized steel coil overview

DX52D galvanized steel coil is a highly formable steel designed for deep drawing and other demanding applications. It is made from a cold-rolled steel coil, hot-dip galvanized to enhance corrosion resistance. After galvanizing, the coil undergoes tempering/quenching and passivation to further enhance corrosion resistance and prepare it for painting or coating.

Benifits

Strong Corrosion Resistance

The zinc coating isolates corrosive media, providing 3-5 times the rust resistance of ordinary steel. It is suitable for humid and salt spray environments.

Easy to Process

It has low yield strength and good toughness, and can be easily deep drawn, bent, and stretched. It can accurately form special-shaped parts such as car doors and home appliance housings without cracking.

Easy to Paint

The smooth and flat surface allows for direct painting or color coating, reducing defects and eliminating secondary processing.

Easy to Weld

The low carbon content (C ≤ 0.12%) makes welding less prone to cracking. No zinc coating removal is required, simplifying the joining process.

High Cost-Effective

With a cost 30%-50% lower than stainless steel, it is a high-quality alternative to stainless steel, offering the quality of stainless steel at a lower cost.

Application

Automotive Industry

Used in the manufacture of vehicle doors, hoods, and other components, require complex curved surfaces. It is also used for interior trim and structural reinforcement, balancing lightweighting with durability.

Home Appliance Manufacturing

Used in appliance housings, refrigerator side panels, washing machine tubs, and other applications, the smooth surface facilitates painting and laminating, enhancing the aesthetics of the exterior.

Architecture and Decoration

It can be processed into lightweight building structures such as wall panels, roof gussets, decorative items, ventilation ducts, and furniture frames.

Hardware and Daily Necessities

Used in the production of hardware accessories, shelves, filing cabinets, household clothes drying racks, storage racks, and other metal products, thanks to its excellent formability.

Agriculture and Animal Husbandry

Select specifications can be used to manufacture agricultural greenhouse supports, fences, granary baffles, and other products. It is corrosion-resistant, adaptable to humid environments, and reduces maintenance costs.

Recommended Configurations by Application

Construction Industry (Roofing/Curtain Wall)

• Recommended Thickness: 0.4- 1.2mm
• Zinc Coating Requirements: Z180-Z275 (double-sided)
• Reasoning: Thicknesses below 0.6mm are suitable for curved roofs, while thicknesses above 1.0mm are suitable for load-bearing structures. High zinc coatings resist rain and salt spray corrosion.

Home Appliance Manufacturing (Refrigerators/Washing Machines)

• Recommended Thickness: 0.5 – 1.0mm
• Zinc Coating Requirements: Z60-Z120
• Key Points: Use Z60 for interior components (e.g., refrigerator back panels); choose Z120 with passivation treatment for exterior components, preferably zero-sparkle coatings.

Automotive Parts (Seats/Fuel Tanks)

• Recommended Thickness: 0.8 – 2.0mm
• Zinc Coating Requirements: Z100 – Z150
• Special Requirements: Welded components must have a zinc coating ≤ Z140 to reduce zinc vapor. A combination of 1.2mm and Z120 is recommended for structural components.

Furniture/Warehousing (Shelves/Display Cabinets)

• Recommended Thickness: 1.0 – 2.5mm
• Zinc Coating Requirements: Z90 – Z150
• Balance: Choose Z90 for indoor environments (e.g., supermarket shelves); use Z150 for high-humidity warehouses.
