·Galvanized steel coil
·Process: A uniform zinc layer is formed on the surface of the steel through hot-dip galvanizing or electroplating.
·Advantages: Strong corrosion resistance, long anti-oxidation life, high cost-effectiveness, widely used in outdoor scenes.
·Common specifications: thickness 0.2-3.0mm, zinc layer weight 60-275g/m ², supports customization.
·Tin plated steel coil
·Process: Adopting electroplating tin technology to endow the steel with excellent sealing and surface smoothness.
·Advantages: Non toxic and environmentally friendly, acid and sulfur resistant, excellent welding performance, suitable for food grade packaging scenarios.
Main specifications: Thickness of 0.15-0.5mm, adjustable tin layer thickness (such as 1.1g/m ²~15g/m ²).
