What are the advantages of hot-dip galvanized bridges?
Publish Time: 2025-01-03
Hot-dip galvanized bridges have many significant advantages compared to ordinary bridges, mainly in terms of corrosion resistance, solid stability, comprehensive protection, workmanship and appearance. The following is a detailed analysis of these advantages:
1. Corrosion resistance
Durable: The anti-corrosion performance of hot-dip galvanized bridges is very good. The zinc layer can resist natural wind and rain erosion for a long time, effectively extending the service life of the bridge. In suburban environments, most hot-dip galvanized bridges can last for more than 50 years without repair, showing extremely strong corrosion resistance.
Hot-dip galvanizing specifications: The specifications of hot-dip galvanizing are generally implemented in accordance with relevant standards, such as BS EN ISO 1461, to ensure that the thickness of the zinc layer meets the rust-proof requirements, and its rust-proof period and performance are reliable and predictable.
2. Solid and stable
Metallurgical bonding: A metallurgical bonding is achieved between the galvanized layer and the steel, making the zinc layer become part of the steel surface, enhancing the overall strength and stability of the bridge.
Enhanced toughness: Over time, the surface of the galvanized layer can form a special metallurgical structure, which further improves the toughness of the bridge and makes it more resistant to external impact and damage.
3. Comprehensive protection
Comprehensive galvanizing: Every part of the hot-dip galvanized bridge can be protected by galvanizing, including recesses, sharp corners and hidden places, ensuring that the entire bridge is protected from corrosion.
4. Advantages of craftsmanship and appearance
Advanced technology: The hot-dip galvanizing process is mature and advanced, which can ensure the uniformity and adhesion of the galvanized layer on the bridge surface and improve the anti-corrosion performance and service life of the bridge.
High surface quality: The surface of hot-dip galvanized bridges is flat and smooth, without scratches, bumps or bumps, which not only improves the aesthetics of the bridge, but also reduces the risk of corrosion caused by surface defects.
High gloss: Hot-dip galvanized bridges usually have a smoother, silver-gray surface with high gloss, which improves the overall texture of the bridge.
Hot-dip galvanized bridges have become the preferred material in bridge construction due to their excellent corrosion resistance, solid stability, comprehensive protection, and process and appearance advantages. These advantages enable hot-dip galvanized bridges to maintain long-term and stable performance in various environments, providing a strong guarantee for people's travel safety.
