Metal privacy fences are favored for their durability, security, and low-maintenance needs, but their lifespan varies greatly depending on the material. While ordinary carbon steel fences may only last 5-15 years, high-quality Corten steel screensstand out for their extraordinarily long lifespan. In this article, we will explore the general lifespan of metal privacy fences, with a focus on analyzing why Corten steel screens are the preferred choice for long-lasting performance.
What Factors Affect the Life Expectancy of a Metal Fence?
Materials
Plain carbon steel: no protective layer, prone to rust, service life of 5-15 years.
Galvanized steel: zinc layer protects against corrosion, service life of 15-25 years, but the coating may gradually peel off.
Stainless steel: due to its high chromium content, it has good rust resistance and service life of 20-50 years, but the price is higher.
Corten Steel Screen: forms a protective rust layer and can be used for more than 30 years even in harsh environments.
Environmental Conditions
Humidity and precipitation: excessive moisture will accelerate the rusting of unprotected metal. Corten steel privacy screensalso perform well in alternating dry and wet environments, forming a stable rust layer.
Salt spray exposure (coastal areas): Salt spray will corrode most metals. In this environment, corten steel screen is more durable than galvanized steel, but require additional maintenance.
Industrial pollution: High concentrations of sulfur can damage paint, but the natural oxide layer on weathering steel resists this attack better than painted metal.
Design and Installation Quality
Drainage: Poorly designed bases can trap water and shorten service life. Weathering steel screens with proper drainage design (such as embossed plates) can avoid this problem.
Material thickness: Thicker steel plates (2 mm and above) are more corrosion-resistant. Weathering steel screens are generally made of 2.5-4 mm thick plates to extend service life.
Installation: Direct contact between dissimilar metals (such as galvanized bolts) can cause galvanic corrosion. Corten steel garden screens should be used with matching fasteners.
Corten laser cut screens form a dense, self-repairing layer of rust within 6-12 months, preventing further corrosion. This rust layer evolves with the environment, enhancing durability without the need for paint or chemical treatments.
Typical Service Life of Corten Steel Screens
Urban / Suburban: 30-50+ years with minimal maintenance.
Coastal / high salt environments: 20-30 years with regular cleaning (to remove salt buildup).
Industrial areas: 25-40 years due to high resistance to corrosion caused by pollution.
What are the Signs that a Metal Fence Needs to be Replaced?
Rust Penetration: The presence of holes or thinning of steel (especially non-Corten steel) indicates structural failure.
Bending / panel damage: deformation due to weather or impact can compromise security.
Loose Fasteners: Rust-damaged bolts or hinges can weaken the integrity of the fence.
Coating discoloration / peeling: painted metal exposing steel will accelerate decay (Corten steel screens do not have this problem because the rust layer is its characteristic).
How Can You Extend The Life Expectancy of A Metal Fence?
For Corten Steel Screens
Annual cleaning: Rinse with water to remove salt, dust or debris (avoid harsh chemicals that can damage the rust layer).
Check drainage: make sure water does not pool at the base and raise the panel if necessary.
Check fasteners: tighten or replace rusted bolts and use fasteners compatible with Corten steel.
For Other Metals
Repaint Every 3-5 Years: Use rust-resistant paint on carbon / galvanized steel.
Galvanized or powder-coated: adds a protective coating, but is not as effective as a rust coating on Corten steel.
