What Is The Average Lifespan Of A Metal Fence?

Metal Mates • January 8, 2025

Have you ever thought about how long a metal fence will last before needing replacement? For property owners, developers and facility managers, a fence isn’t just about appearance—it’s about durability, longevity and value. Metal fences are known for their strength and can last for decades, but how long exactly? In this blog, we’ll explore the average lifespan of a metal fence and the key factors that affect it.

Material Matters

The metal used in your fence significantly impacts its lifespan. Common materials like aluminium, steel and wrought iron each differ in strength, corrosion resistance and durability.

Aluminium fencing: Lightweight, corrosion-resistant and low-maintenance fences can last 30+ years with proper care. While not as strong as steel, aluminium won’t rust, making it ideal for coastal areas.
Steel fencing: Extremely durable and strong, galvanised or stainless steel fences can last 20 to 50 years, making them suitable for high-traffic or industrial spaces.
Wrought iron fencing: Known for its classic, ornamental appearance, wrought iron fences are durable but require regular maintenance to prevent rusting.

Weather Conditions

Your property’s location greatly impacts the lifespan of your metal fence. Weather conditions can speed up wear and tear, even on durable materials. For example, coastal areas expose fences to salty air, leading to corrosion over time. High humidity and frequent rain can also cause rust if the fence isn’t properly treated.

Metal fences tend to last longer in dry, temperate climates as they face fewer rust-inducing conditions. If your property is in a rainy or coastal area, consider using corrosion-resistant metals like aluminium or ensuring your fence is properly galvanised to prevent rust.

Installation Quality

Even the highest-quality metal fence won’t last long if poorly installed. Professional installation ensures the fence is secured properly, preventing issues like sagging, leaning or gaps. Misaligned posts or improper anchoring can compromise the integrity of the fence, leading to premature wear.

Hiring an experienced professional to install your fence ensures that it’s done correctly the first time, maximising its lifespan and saving you from costly repairs down the line.

Maintenance

Maintenance is key to extending the lifespan of a metal fence. Although metal fencing requires less upkeep than wood, periodic care is still necessary. Regular inspections catch small issues before they escalate.

Here are some tips to prolong your fence’s life:

Clean regularly: Use water and mild soap to remove dirt, debris and salt buildup, especially in coastal areas.
Inspect for rust: Check for rust and apply a rust inhibitor or touch-up paint when needed.
Trim vegetation: Keep plants away from the fence to prevent trapped moisture and rust.
Repair promptly: Fix loose posts, bent sections or broken parts immediately to avoid further damage.

Cost Vs Longevity

While metal fences tend to be more expensive upfront compared to wood or vinyl, their long lifespan makes them a worthwhile investment. When you factor in the low maintenance requirements and durability, a metal fence can often end up costing less over time than fences made from less durable materials. A well-maintained metal fence can last multiple decades, far outlasting other options and offering better value in the long run.
