Temporary Steel Pedestrian Bridge/temporary Steel Modular Bridge
Common protective coatings used for steel bridges include several types of multi-layer systems designed to provide long-lasting protection against corrosion and environmental degradation. Here are the most widely used coating systems:
1. **Zinc-Rich Primer Coatings**:
- **Inorganic Zinc (IOZ)**: These primers use zinc metal powder mixed with an inorganic silicate binder. They provide excellent cathodic protection and are often used in highly corrosive environments, such as coastal areas.
- **Organic Zinc (OZ)**: These primers contain zinc metal pigment mixed with organic resins like epoxy or polyurethane. They are easier to apply and cure compared to inorganic zinc primers.
2. **Three-Coat Systems**:
- **Zinc-Rich Primer**: Provides sacrificial protection to the steel.
- **Epoxy Midcoat**: Adds thickness and durability, enhancing the barrier properties against moisture and corrosive agents.
- **Polyurethane or Fluoropolymer Topcoat**: Provides UV resistance, weather protection, and excellent gloss and color retention. Fluoropolymer-based topcoats, such as those using FEVE (fluoroethylene vinylether), offer superior durability and longevity.
3. **Metallizing and Galvanizing**:
- **Metallizing**: Involves applying a layer of zinc or a zinc-aluminum alloy to the steel surface using thermal spraying. This method provides excellent corrosion protection and can be further enhanced with a sealer and polyurethane topcoat.
- **Hot-Dip Galvanizing**: Immersing steel structures in molten zinc to form a protective coating. This method offers superior corrosion resistance and has the highest practical maintenance times, often exceeding 70 years in moderately corrosive environments.
4. **Weathering Steel**:
- **Uncoated Weathering Steel**: Contains small amounts of alloying elements like copper, nickel, chromium, and silicon. These elements form a protective patina that adheres tightly to the surface and provides corrosion resistance. However, this method is less effective in highly corrosive environments and may require additional coatings or thickness.
5. **Alkyd Systems**:
- These systems are less commonly used due to their lower protection levels compared to zinc-based coatings. They typically consist of alkyd-based primers and topcoats and are suitable for less aggressive environments.
The choice of coating system depends on factors such as the environment, expected durability, and life-cycle costs. Zinc-rich primers and multi-coat systems with polyurethane or fluoropolymer topcoats are widely used for their robustness and long service life.
