Product Description

DX56D+Z galvanized steel sheet is created through an advanced hot-dip galvanizing process, where a steel sheet is submerged in molten zinc to form a protective zinc layer on its surface. This continuous process ensures a uniformly coated, high-quality galvanized steel sheet with excellent durability.For enhanced performance, our alloyed galvanized steel sheet undergoes an additional step: after the initial zinc coating, it is heated to approximately 500°C, allowing the formation of a zinc-iron alloy layer. This alloy layer significantly improves the coating’s adhesion and the sheet’s weldability, making it a reliable choice for demanding applications.

Application

the DX56D galvanized sheet for wedded pipeline

DX56D GALVANIZED SHEET FOR WElDED PIPELINE

“DX56D galvanized sheet” can be used to manufacture various types of pipelines, such as water supply pipelines, oil pipelines, natural gas pipelines, etc. Its corrosion resistance can effectively extend the service life of pipelines.

GALVANIZED CORRUGATED SHEET

GALVANIZED SHEET FOR ROOFING PLATE 

After being pressed by abrasive tools, “DX56D+Z galvanized plate” can be used to make Gi corrugated sheet , which are widely used in building roofs, walls, isolation boards, and other products. This galvanized sheet has excellent waterproofing and durability properties and can effectively protect buildings from moisture intrusion and environmental corrosion. Its corrugated design also adds to the structural strength and aesthetics of the building.

DX56D GALVANIZED SHEET FOR OIL TANK

DX56D GALVANIZED SHEET FOR OIL TANK

DX56D+z galvanised sheet is an excellent metal material that can be used to manufacture various types of containers, such as storage tanks, barrels, etc. Oil tanks are made of DX56D galvanized sheets. Due to the corrosion resistance of the galvanized layer, it can effectively protect the contents inside the container from the external environment. The protective layer formed by the zinc coating on the surface can prevent the erosion of oxygen, moisture, and other corrosive substances, thus extending the service life of the container and ensuring the safety of stored items. Therefore, in the industrial field, DX56D galvanized sheet containers can provide reliable anti-corrosion protection to ensure the quality and stability of stored items.

Production Process

THE PRODUCTION PROCESS OF DX56D GALVANIZED SHEET

  • Preparation of the Steel Coil
    The process begins with a steel coil, which is carefully cleaned and prepped to remove any impurities. This ensures the steel surface is optimal for zinc adhesion and prevents defects in the final coating.
  • Continuous Annealing
    The steel coil is heated to a specified temperature to adjust its mechanical properties. This annealing step makes the steel softer and enhances its formability, which is ideal for applications requiring deep drawing.
  • Hot-Dip Galvanizing
    The steel strip passes through a molten zinc bath in a continuous process. This hot-dip coating forms a strong, corrosion-resistant zinc layer on the surface. For DX56D+Z, this layer is evenly applied and has excellent uniformity.
  • Alloying Treatment
    After the initial zinc coating, the steel is immediately heated to about 500°C. This additional heating step allows the zinc and iron to bond, forming a zinc-iron alloy layer. The alloyed layer improves the coating’s durability and provides enhanced adhesion, making it ideal for painting or welding.
  • Cooling and Passivation
    The galvanized sheet is rapidly cooled to solidify the coating and then treated with a passivation layer. This helps prevent oxidation and maintains the sheet’s surface appearance during storage and transportation.
  • Quality Inspection
    Each coil undergoes strict quality control tests to ensure coating thickness, adhesion, and surface finish meet DX56D+Z specifications. Only sheets that pass inspection proceed to packaging and distribution.
