galvanized steel coil
Looking for trusted galvanized steel coil manufacturers in China? You've come to the right place. As a direct factory with 20 years of structural steel experience, GNEE Steel supplies high-quality coils at factory prices. In this guide, we'll detail the specifications of S350GD galvanized steel coil and help you understand its applications and advantages.
Galvanized steel coil
Galvanized steel is a type of steel with a protective zinc coating to prevent rusting. This coating extends the material's lifespan significantly compared to regular carbon steel.
S350GD galvanized steel coil is widely used in construction, automotive manufacturing, and home appliances. Its excellent corrosion resistance makes it ideal for outdoor and humid environments.
Common galvanized steel grades include S250GD, S350GD, S450GD, each differing in strength and application scenarios.
Chemical Composition of S350GD Galvanized Steel Coil
The chemical composition of S350GD galvanized steel coil directly affects its performance. The following table outlines the standard chemical components:
| Element | Content (Max, %) |
|---|---|
| C | 0.12 |
| Si | 0.50 |
| Mn | 1.60 |
| P | 0.035 |
| S | 0.035 |
| Al | 0.020 |
| Ti | 0.22 |
This composition ensures the steel coil has both high strength and good formability, suitable for various processing needs.
