A Comprehensive Guide to Galvanized Sheets in China
Galvanized sheets, also known as galvanized steel sheets, are essential materials in various industries due to their excellent corrosion resistance and durability. In China, several manufacturers and suppliers specialize in producing high-quality galvanized sheets, catering to both domestic and international markets. This guide will explore the technical features, types, and applications of galvanized sheets, providing insights into their significance in construction, automotive, and other sectors.
Technical Features of Galvanized Sheets
Galvanized sheets are made by coating steel with a layer of zinc to protect it from corrosion. The zinc layer acts as a barrier against moisture and environmental factors that can lead to rust. Below is a comparison table highlighting the key technical features of galvanized sheets:
| Feature | Description |
|---|---|
| Thickness | Ranges from 0.11 mm to 4.0 mm, depending on the application. |
| Width | Available in widths from 600 mm to 1250 mm. |
| Zinc Coating | Varies from 30 g/m² to 275 g/m², influencing corrosion resistance. |
| Spangle Type | Options include zero spangle, regular spangle, and big spangle. |
| Grade | Common grades include SGCC, DX51D, and others based on standards. |
| Surface Treatment | Treatments include chromated, oiled, and non-oiled finishes. |
| Standard Compliance | Meets ASTM, AISI, and other international standards. |
| Processing Services | Includes bending, welding, decoiling, cutting, and punching. |
Types of Galvanized Sheets
Galvanized sheets come in various types, each suited for specific applications. The following table outlines the different types of galvanized sheets available in the market:
| Type | Description |
|---|---|
| Regular Spangle | Features a visible spangle pattern, providing aesthetic appeal. |
| Zero Spangle | Has a smooth surface without spangle, ideal for painting and coating. |
| Prepainted Galvanized | Coated with paint before galvanization, offering additional protection. |
| Hot-Dip Galvanized | Steel is immersed in molten zinc, providing a thick and durable coating. |
| Electro-Galvanized | Coated with zinc through electroplating, offering a thinner layer. |
| Galvalume | Coated with a mixture of aluminum and zinc, enhancing corrosion resistance. |
