Surface treatment improves rust resistance, wear resistance and appearance of fasteners. Different processes fit different working environments and budget demands.
| Treatment | Rust Resistance | Wear Resistance | Appearance | Main Application |
| Electro-galvanizing | Medium | Normal | Bright silver | Indoor machinery & electronics |
| Hot-dip galvanizing | Good | Good | Thick zinc layer | Outdoor steel structures |
| Nickel plating | Good | Excellent | Bright metallic | Precision & decorative parts |
| Black oxide | Normal | Good | Matte black | Machine tools & high temp parts |
| Dacromet | Excellent | Good | Silver gray | PV & coastal facilities |
Electro-galvanizing is cost-effective for general indoor use. Hot-dip galvanizing works well for outdoor steel structures. Nickel plating is ideal for products with appearance requirements. Black oxide suits high-temperature mechanical parts. Dacromet is the best choice for highly corrosive environments.
