Galvanized steel strip is a versatile and corrosion-resistant material produced by coating cold-rolled steel strip with a protective layer of zinc. This process, known as galvanization, creates a durable product ideal for applications where rust prevention is critical. At ChinaCNU Steel, a leading zinc steel strip factory in Qingdao, we specialize in manufacturing high-quality galvanized steel strip, including narrow GI strip and slit galvanized coil, for a global industrial clientele. Our products are engineered to meet rigorous international standards, offering superior performance and longevity in demanding environments.

FAQ
What is the typical lead time for a 50-ton order of galvanized steel strip?
For a standard 50-ton order of galvanized steel strip, our typical production and shipping lead time is between 15 to 25 days from receipt of deposit and confirmed specifications. This efficient timeline is possible because we are a direct factory with controlled production lines. For custom requirements like specific narrow GI strip dimensions, we will provide a precise schedule with your quote.
Can you supply small quantities of slit galvanized coil for testing or a pilot project?
While our standard Minimum Order Quantity (MOQ) is 25 tons for bulk commercial orders, we understand the need for sample testing. We can often arrange smaller quantities of slit galvanized coil for trial purposes. Please contact our sales team with your detailed requirements, and we will strive to find a feasible solution to support your project development.
What are the main differences between standard GI strip and prepainted (PPGI) strip?
Standard galvanized steel strip (GI) has a zinc coating for corrosion resistance. Pre-painted galvanized steel strip (PPGI) undergoes an additional process where a colored paint or polyester coating is applied over the zinc layer. This provides enhanced aesthetics, additional protection against weathering and chemicals, and eliminates the need for post-fabrication painting, making it ideal for visible architectural applications.
What payment terms do you accept for international buyers of zinc steel strip?
For international buyers, we offer secure and flexible payment terms to facilitate smooth transactions. We commonly accept Telegraphic Transfer (T/T) with a deposit against proforma invoice, with the balance paid before shipment or against copy of shipping documents. We also accept Letters of Credit (L/C) at sight for established business partners. Our sales team will work with you to agree on the most convenient terms.
