Galvanized steel sheet, also known as GI plain sheet or zinc coated sheet, is a cold-rolled steel substrate coated with a protective layer of zinc to prevent rust and corrosion. This essential construction and manufacturing material offers superior durability and longevity, making it a fundamental choice for a wide range of industrial and architectural applications. As a leading galvanized iron sheet factory in Qingdao, ChinaCNU Steel produces high-quality galvanized steel sheets for export to global markets, ensuring consistent performance and reliability.
Our galvanized steel sheets are manufactured to exacting standards, available in a comprehensive range of specifications to meet diverse project requirements. Below is a detailed overview of our standard product specifications.

The versatility of galvanized steel sheet makes it indispensable across numerous sectors. Its corrosion resistance and strength are utilized in:
Selecting the right supplier for your galvanized iron sheet is critical. Here’s why global buyers trust ChinaCNU Steel:
Pricing for our galvanized steel sheet (GI) and color-coated galvanized sheet (PPGI) is based on current raw material costs, zinc coating weight, dimensions, and order volume. We offer competitive FOB Qingdao pricing, providing a significant logistical advantage for global shipping. For the most accurate and up-to-date quote tailored to your specific grade, thickness, and coating requirements, please contact our sales team directly. We provide free, no-obligation quotations within 24 hours.
GI sheet refers to the standard galvanized steel sheet with a zinc coating for corrosion protection. PPGI (Pre-Painted Galvanized Iron) is a GI sheet that has undergone an additional process where a colored paint or polyester coating is applied on top of the zinc layer. This provides both corrosion resistance and an aesthetic finish, making PPGI ideal for architectural applications like roofing where color is important.
Common zinc coating weights, expressed in grams per square meter (g/m²), range from Z60 (light coating) to Z275 (heavy coating). For instance, a Z120 coating is a standard choice for general construction, while Z180 or Z275 is specified for more corrosive environments like coastal areas or industrial zones. We can produce according to ASTM, EN, and JIS standards.
From our Qingdao factory, the total lead time—including production and shipping—for galvanized sheet orders to the Middle East is typically between 15 to 25 days. This timeframe can vary slightly based on the specific port of destination and current vessel schedules. We provide detailed logistics planning upon order confirmation.
Yes, absolutely. As a certified manufacturer, we provide full Mill Test Certificates (MTCs) or Material Test Reports with every shipment. These documents verify the chemical composition, mechanical properties, and coating weight of the galvanized steel sheets, ensuring they meet the specified international standards. SGS third-party inspection can also be arranged.
