Comparison table of structure qualities and functions compared to conventional technologies
| Flow rate | Iron structure (Conventional technology) |
Aluminum structure (Conventional technology) |
PGF light-weight structure (Developed technology) |
|---|---|---|---|
| Specific gravity | 7.85 | 2.8 | 1.85 |
| Tensile strength | 400Mpa | 170Mpa | 500Mpa |
| Corrosion resistance |
Durability concern including corrosion Repeated maintenance is required |
Good durability in wet environment Concerns about durability in salt environment |
Good durability in wet environment and salt environment |
| Constructability | Heavy equipment is required due to heavy weight Experienced engineers are required |
Good constructability Experienced engineers are required |
Construction can be performed by non-professional persons |
| Economics | Excessive floating bodies are needed Construction takes a long time |
Floating body requirements are reasonable, but material cost is high. | Mass production is possible and construction period can be shorten |
| Environmental safety | Necessity to review environmental properties such as corrosion | Conforming to Article 24 Sanitary and Safety Standards of Water Supply and Waterworks Installation Act | Conforming to Article 24 Sanitary and Safety Standards of Water Supply and Waterworks Installation Act |
