Galvanized steel strip refers to a type of steel strip that has been coated with a layer of zinc through a process called galvanization. Galvanization is a common method used to protect steel from corrosion and extend its lifespan.

The process of galvanization involves immersing the steel strip into a bath of molten zinc or applying a zinc coating onto the surface of the strip through other means, such as electroplating. The zinc coating forms a protective layer over the steel, acting as a barrier against corrosive elements like moisture and chemicals.

Galvanized steel strips are commonly used in various industries and applications, including construction, automotive, electrical, and manufacturing. They are valued for their corrosion resistance, durability, and versatility. Galvanized steel strips can be formed, bent, and shaped into different profiles, making them suitable for a wide range of uses, such as in the production of roofing materials, ductwork, automotive parts, and electrical enclosures.

The thickness, width, and other specifications of galvanized steel strips can vary depending on the specific requirements of the application. These strips are available in different grades and finishes to meet different performance and aesthetic needs.

◆ 1. Pre-Treatment Process

Some rolling oil and other contaminants remain on the surface of cold rolled steel sheets following processing. These are removed by passing the electrically charged sheet through an alkaline solution which induces an electrochemical reaction.

◆ 2. Annealing

The material properties of the pre-treated steel sheet can be altered and improved through recrystallization during the annealing process.

◆ 3. Hot-Dip Galvanizing

After passing through the annealing furnace, steel sheets are dipped into a zinc pot where molten Zn is coated onto the surface. The desired coating weight is achieved by removing excess zinc before solidification with high-pressure air from an air knife.

◆ 4. Galvannealing

The surface of a steel sheet, after the air knife, can be coated with a zinc compound prior to reheating in an annealing process. Zn atoms diffuse into the Fe to create a Zn-Fe series alloy.

◆ 5. SPM & Chemical Treatment

In order to achieve a flat surface and an elegant finish, the steel sheet is processed with a skin pass mill. In order to prevent the white rust, which often forms on the surface of activated zinc, and to improve corrosion resistance, the surface is coated with a Cr-free resin.

◆ 6. Inspection & Coiling

Located at the line’s exit section are a side trimmer, inspection table, oil coating machine and coiling equipment. At this station, all products are inspected and judged relative to material specifications required by the customer.
