Galvanized Steel Sheet

Galvanized steel sheet is a welded steel sheet with a hot-dip galvanized or electro-galvanized layer on the surface. Gnee provides galvanized steel plain sheet, galvanized steel checker plate and corrugated sheet. It has good processing performance. The zinc layer has uniform thickness, strong adhesion, no peeling during processing and good corrosion resistance.

Gnee Steel is a leading manufacturer and exporter of galvanized steel products, specializing in high-quality galvanized steel sheets. Our galvanized steel sheets are available in various sizes, thicknesses, and coating weights to meet the specific needs of different applications. Our galvanized steel sheets can be easily bent, shaped, and fabricated without compromising the integrity of the zinc coating, making them ideal for various manufacturing processes.

  1. Cleaning: Before the galvanization process begins, the steel sheet is thoroughly cleaned to remove any impurities, such as rust, oil, or mill scale. This cleaning is typically done using a combination of acid and/or alkaline solutions.
  2. Pickling: The cleaned steel is then immersed in an acidic solution, usually a mixture of hydrochloric acid or sulfuric acid, to remove any remaining oxides and prepare the surface for zinc coating. This step is known as pickling.
  3. Fluxing: After pickling, the steel is fluxed to remove any residual acid and to promote the formation of a uniform zinc coating. Fluxing is often done by passing the steel through a flux solution or by applying a powdered flux.
  4. Galvanizing: The steel sheet is immersed in a bath of molten zinc at temperatures typically around 450°C (850°F). The zinc reacts with the steel surface to form a series of zinc-iron alloy layers, providing a durable and corrosion-resistant coating.
  5. Cooling: After the galvanizing process, the coated steel sheet is allowed to cool. This cooling can be done in the air or through a controlled cooling process to ensure the formation of a strong bond between the zinc coating and the steel substrate.
  6. Inspection: The galvanized steel sheets are inspected to ensure that the coating is uniform and meets the required standards for thickness and appearance.
