Hot-dip galvanization significantly enhances the durability of Bailey bridges by providing several key benefits:
1. **Metallurgical Bond and Bond Strength**:
The galvanizing process creates a strong metallurgical bond between the zinc coating and the steel, resulting in a bond strength of approximately 3,600 psi. This bond ensures that the coating becomes an integral part of the steel, rather than just a surface treatment, providing long-lasting protection against corrosion.
2. **Uniform Protection and Complete Coverage**:
The galvanized coating grows evenly across the entire surface of the steel, including edges and corners, ensuring uniform protection. This uniformity is crucial for maintaining the structural integrity of the bridge, especially in harsh environments.
3. **Abrasion Resistance**:
The galvanized coating consists of hard intermetallic layers (Gamma, Delta, and Zeta) that are harder than the underlying steel. These layers provide exceptional resistance to abrasion and impact, protecting the steel from damage during transportation, installation, and service.
4. **Predictable Coating Thickness**:
The thickness of the galvanized coating is directly proportional to the thickness of the steel being galvanized. This predictability ensures consistent protection and helps in estimating the service life of the bridge components.
5. **Long-Term Corrosion Protection**:
The galvanized coating provides long-term corrosion protection, with the corrosion rate slowing down over time. In some cases, the coating can last up to 40 years before requiring maintenance.
6. **Environmental Resistance**:
Hot-dip galvanized steel can withstand continuous exposure to temperatures up to 20°C and occasional excursions up to 275°C without affecting the coating. This makes it suitable for various environmental conditions, including marine and industrial atmospheres.
By using hot-dip galvanization, Bailey bridges manufactured by Jiangsu Zhonghai Bridge Equipment Co., Ltd. achieve enhanced durability, ensuring they can withstand harsh conditions and heavy loads while maintaining a long service life.
