The application of aluminum profiles in bridge construction has gradually increased in recent years, mainly due to its light weight, high strength, corrosion resistance and easy processing. The following describes the application form, advantages and typical cases:
1. Main application forms of aluminum profiles
Bridge deck structure and pavement
Aluminum profiles can be used for bridge decks (especially pedestrian bridges or light vehicle bridges). Extruded aluminum alloy panels have good load-bearing capacity while weighing much less than traditional steel or concrete.
2. Advantages of aluminum profiles in bridge construction
1. Lightweight
The density of aluminum is about 1/3 of steel, which greatly reduces the weight of the bridge, thus:
Reduce base load
Easy to transport and hoist
2. Excellent corrosion resistance
Aluminum will form a dense oxide film in the air and has strong corrosion resistance. It is especially suitable for:
marine environment
Industrial pollution areas
3. High construction efficiency
High extrusion molding precision
Can realize standardized and modular design
Short installation cycle
4. Low maintenance cost
There is no need for frequent anti-corrosion coating, and long-term use costs are low
5. Highly recyclable
Aluminum is 100% recyclable and conforms to the green building concept
