Product Description
Comparison of Raw Materials
Type | Base Material (Grade) | Core Features | Surface Condition | Main Advantages | Main Disadvantages |
Cold Rolled Steel | Low Carbon Steel (SPCC) | Requires coating for rust prevention | Smooth, can be painted with various colors | Low cost, aesthetic, easy to process | Rust protection relies on coating |
Galvanized Steel | Low Carbon Steel (DX51D+Z) | Comes with zinc coating for rust prevention | Silver-gray spangle pattern, paintable | Best overall rust resistance and cost-performance ratio | Slightly more expensive than cold rolled steel |
Stainless Steel (304) | Chromium-Nickel Alloy Steel (SUS304) | Excellent intrinsic corrosion resistance | Metallic color (silver/rose gold) | Extremely durable, maintenance-free | Expensive, limited style options |
Stainless Steel (201) | Chromium-Nickel Alloy Steel (SUS201) | Relatively poor corrosion resistance | Metallic color | Cheaper than 304 | Prone to rust, substandard performance |
