Frequently Asked Questions (FAQ)
What is the difference between SGCC and GI galvanized steel?
SGCC refers specifically to the Japanese Industrial Standard (JIS G3302 SGCC) for hot-dip zinc-coated steel sheets and coils, often detailing specific quality designations. GI (Galvanized Iron) is a more general term. When you source SGCC galvanized steel coil, you are getting a product that conforms to the precise chemical and mechanical properties outlined in the JIS standard, which is widely recognized and trusted in international trade.
Can you supply SGCC coils with a spangle surface finish?
Yes, as a professional SGCC steel supplier, we can produce coils with a regular spangle, minimized spangle, or extra-smooth finish based on your application needs. The spangle size and appearance can be controlled during the galvanizing process. Please specify your surface finish requirement when requesting a quote for your SGCC zinc coated material.
What payment terms do you accept for bulk orders?
For international B2B transactions, we offer secure and flexible payment terms, primarily by Telegraphic Transfer (T/T) and Letter of Credit (L/C). Our standard terms are 30% deposit with order confirmation and 70% balance against copy of shipping documents, though we can discuss other arrangements for established partners.
How do you ensure the corrosion resistance of your SGCC zinc coated coils?
The corrosion resistance is directly determined by the zinc coating mass, measured in grams per square meter (g/m²). Our SGCC galvanized steel coil is produced with precise control over the galvanizing bath and air-knife process to achieve a uniform coating that meets the specified weight (e.g., Z60, Z120, Z180 per JIS standard). A heavier coating provides longer-lasting protection against rust in harsh environments.
