The high strength hot dip DX53D+Z galvanized steel coil is a very good product of hot-dip galvanizing metal. This kind of metal is very good regarding anti-corrosion together with metallic property preservation. To keep the base metal, which is steel, from rusting, it is dipped in molten zinc creating a zinc coating barrier over the surface. It is a high strength and good rigidity material that caters to the industrial processing requirement. The specifications for our galvanized steel coils can be customized as per the customer’s requirement. However, generally, we deal in thickness varying from 0.2mm to 4.0mm with a width range of 600mm to 1500mm.

 Surface Structure

The image in the Surface Structure section showcases the different spangle types available for Shunbei's Gi Coil DX53D+Z Galvanized Steel Coils. From left to right, the image displays no spangle, small spangle, regular spangle, and big spangle finishes. The varying spangle sizes are a result of the zinc crystallization patterns formed during the cooling process of the hot-dipped galvanizing procedure.

The no spangle finish exhibits a smooth, uniform surface devoid of any visible zinc crystal patterns. This finish is ideal for applications requiring a sleek and consistent appearance. The small spangle finish features a subtle and refined zinc crystallization pattern, offering a balance between aesthetics and corrosion protection. The regular spangle finish, the most common type, displays a moderate and uniform zinc crystal pattern, providing a classic galvanized look. Finally, the big spangle finish boasts larger, more prominent zinc crystals, creating a distinctive and visually striking appearance.

The cross-sectional view of the coil, presented in the lower part of the image, reveals the layers that make up the Gi Coil DX53D+Z Galvanized Steel Coils. The base metal, typically cold-rolled steel, forms the core of the coil. It is then coated with a layer of zinc, which provides the primary corrosion protection. An additional chromium-free passivation coating is applied over the zinc layer to enhance the coil's resistance to oxidation and corrosion, ensuring long-lasting performance in various environments.

 Product Process

the process of DX53D+Z Gi coil


  • Steel Making and Casting

  • Hot Rolling

  • Pickling

  • Cold Rolling

  • Annealing

  • Galvanizing

  • Post-Galvanizing Treatments

  • Quality Control

  • Slitting and Cutting

  • Packaging and Shipping


1.Steel Making and Casting

Raw Material Preparation: Iron ore, coke, and limestone are processed in a blast furnace to produce molten iron.

Basic Oxygen Furnace (BOF) or Electric Arc Furnace (EAF): The molten iron is converted into steel by removing impurities and adjusting the chemical composition.

Casting: The molten steel is then cast into slabs through a continuous casting process.

2.Hot Rolling

Reheating: The steel slabs are reheated to around 1200°C in a reheating furnace.

Rough Rolling: The reheated slabs pass through roughing mills to achieve preliminary thickness reduction.

Finish Rolling: Further rolling in the finishing mills reduces the thickness to the desired level, producing hot-rolled coils.

3.Pickling

Cleaning: The hot-rolled coils are cleaned in a pickling line using hydrochloric acid to remove the oxide scale formed during hot rolling.

4.Cold Rolling

Thickness Reduction: The pickled coils are cold rolled at room temperature to achieve precise thickness and improved surface finish. This process also enhances the mechanical properties of the steel.

5.Annealing

Batch Annealing or Continuous Annealing: The cold-rolled coils are annealed to restore ductility by recrystallizing the grain structure. Batch annealing is done in sealed furnaces, while continuous annealing involves passing the steel through a series of heating and cooling zones.

6.Galvanizing

Surface Preparation: The annealed coils are cleaned and prepped for galvanizing.

Hot-Dip Galvanizing: The steel passes through a molten zinc bath at temperatures around 450°C. This process coats the steel with a layer of zinc, providing corrosion resistance.

Air Knives: After exiting the zinc bath, the thickness of the zinc coating is controlled using high-pressure air knives.

7.Post-Galvanizing Treatments

Chromating or Passivation: To enhance corrosion resistance and adhesion properties for subsequent painting or coating, the galvanized steel may undergo chromatin or passivation treatments.

Oiling: Applying a thin oil layer helps protect the surface from corrosion during storage and transportation.

Skin Passing: A light rolling process improves surface finish and mechanical properties, reducing the appearance of defects such as fluting.

8.Quality Control

Inspection: The galvanized coils are inspected for coating thickness, surface quality, mechanical properties, and chemical composition to ensure compliance with standards.

Testing: Various tests, including tensile tests, elongation tests, and coating adherence tests, are conducted to verify the quality.

9.Slitting and Cutting

Slitting: The coils can be slit into narrower widths as per customer requirements.

Cutting to Length: The coils may also be cut into sheets of specified lengths.

10.Packaging and Shipping

Coil Packaging: The coils are carefully packaged to protect against physical damage and environmental exposure during transportation.

Shipping: The final products are then shipped to customers for various applications.
