Hot-dip galvanized coils: These coils are dipped into molten zinc, resulting in a thicker coating that provides superior protection against rust and corrosion. They are ideal for heavy-duty, outdoor applications.
Electro-galvanized coils: These coils are coated using an electrolytic process, which results in a thinner, more uniform coating. They are typically used in applications requiring smoother finishes, such as in electronics or automotive components.
The main benefit of galvanized coil over regular steel coil is its corrosion resistance. The zinc coating protects the steel from rust and deterioration caused by exposure to moisture, chemicals, and extreme weather. This results in a longer lifespan and lower maintenance costs compared to uncoated steel.
Yes, many suppliers, including Baiyoung, offer custom lengths and thicknesses for galvanized coils to meet specific B2B requirements. Custom orders are ideal for projects that need specific measurements to reduce material wastage and improve efficiency. Typically, orders in bulk allow for more flexibility in customizing coil dimensions.
Yes, certain grades of galvanized coils are designated based on the thickness of the zinc coating and the steel’s mechanical properties. For instance:
Grade 230: Common for medium thickness applications, offering good corrosion resistance.
Grade 450: Often used for thicker, high-strength galvanized coils with enhanced durability for heavy-duty uses like industrial equipment and structural components.
