Minor ATON structures are commonly made from what materials?

• A. Wood or concrete piles, steel piles, or other steel structural shapes
• B. Plastic only
• C. Glass fiber only
• D. Stone blocks

Answer: (A)

Minor ATON structures rely on driven supports that must stand up to wave action, ice, and saltwater over long periods. The best materials for these piles are wood, concrete, or steel (including various steel structural shapes) because they offer the right balance of strength, rigidity, and durability, and they’re practical to drive into the seabed or install where the structure sits. Wood and concrete piles work well in lighter or more sheltered installations, while steel piles provide higher strength for harsher conditions or heavier structures. Plastic, glass fiber, and stone blocks don’t fit these typical needs. Plastic ages and degrades in saltwater, glass fiber isn’t usually used for core load-bearing piles in marine environments, and stone blocks aren’t practical as driveable supports or as durable, long-term structural foundations for ATONs.
