Hot Dipped Gi Steel Sheet Zinc Coated Galvanized Plain Steel Sheet Galvanized Steel Plate
A galvanized steel roll refers to a continuous coil of galvanized steel that is wound onto a spool or roll. It is a long, continuous sheet of steel that has been coated with zinc through the process of galvanization.
The galvanization process involves immersing the steel roll in a bath of molten zinc or applying a zinc coating onto its surface. This zinc coating provides protection against corrosion, making the steel more resistant to rust and extending its lifespan.
Galvanized steel rolls are commonly used in various industries and applications. They are particularly valued in construction, where they are used for roofing, siding, and structural components. Galvanized steel rolls are also used in manufacturing processes for products such as pipes, tubes, HVAC systems, automotive parts, and electrical enclosures.
The dimensions and specifications of galvanized steel rolls can vary, including the thickness, width, and length, depending on the specific requirements of the application. These rolls are available in a range of 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.
