Frequently Asked Questions
Q: What is the difference between hot-dip and electro-galvanized steel plates?
Hot-dip galvanized steel plates are made by immersing the steel in a molten zinc bath, resulting in a thicker coating and superior corrosion resistance. Electro-galvanized steel plates have a thinner, electroplated zinc layer, which offers excellent processability but less corrosion resistance compared to hot-dip options.
Q: What are the standard dimensions available for galvanized steel coils?
Our galvanized steel coils come in thicknesses ranging from 0.12 mm to 5.0 mm and widths ranging from 90 mm to 1500 mm, fitting a wide variety of industrial and manufacturing requirements.
Q: What are the typical applications of these galvanized steel sheets?
They are widely used in home appliances such as refrigerators, washing machines, air conditioning units, microwave ovens, lighting fixtures, televisions, and audio/video equipment.
Q: How are the steel coils packaged for shipping and delivery?
The products are packaged securely in bundles, plastic bags, thin film, and wooden pallets to ensure standard seaworthy export packing. Custom packaging can also be arranged based on specific customer demands.
Q: Which container sizes do you offer for logistics?
We offer shipping in 20ft GP (capacity 24-26 CBM), 40ft GP (capacity 54 CBM), and 40ft HC (capacity 68 CBM) containers to accommodate different volume requirements.
Q: Why is element composition testing important for the steel sheets?
Testing the percentage of elements like Carbon, Chromium, Cobalt, and Nickel ensures the steel meets strict quality standards. This guarantees optimal hardness, tensile strength, corrosion resistance, and ductility for industrial use.
