____ ornamental fence is most widely used material but requires the most maintenance.

• A. Galvanized steel
• B. Welded steel
• C. Aluminum
• D. Welded steel assembled

Answer: (B)

Welded steel is the material most commonly used for ornamental fences because it can reproduce the classic iron look with strong, decorative designs at a reasonable cost. The downside is maintenance: steel will rust where its coating is damaged, and welds are particularly vulnerable. To keep a welded-steel fence looking good and lasting, you need regular inspections for rust, touch-up painting, and re-coating as needed. Aluminum resists corrosion and requires less upkeep, and galvanized steel has protective zinc but still needs maintenance where coatings wear or are scratched. So, even though welded steel is the prevalent ornamental choice, it demands the most ongoing maintenance to prevent rust and preserve appearance.
