ISO 9227 Aluminum Fence Salt Rating
SLEEKFENCE™ aluminum fencing systems are widely specified for their durability, low maintenance, and refined architectural appearance. However, in high-exposure environments, long-term performance is directly influenced by resistance to corrosion—particularly from salt.
Salt corrosion can originate from natural sources such as coastal air and seawater, as well as from urban conditions like road de-icing salts. These environments can accelerate deterioration in many exterior materials. This document outlines the ISO 9227 salt spray performance of SLEEKFENCE™, providing a clear benchmark for corrosion resistance in demanding conditions.
What is the ISO 9227 Salt Spray Test?
The ISO 9227 salt spray test is an internationally recognized standard used to evaluate the corrosion resistance of metallic materials and coatings.
The test exposes material samples to a controlled saltwater mist environment over a defined period. This accelerated testing method simulates long-term exposure to salt-laden conditions and measures how effectively a material resists corrosion and coating breakdown.
SLEEKFENCE™ Test Result:
After 1000 hours of salt spray exposure, SLEEKFENCE™ demonstrated a maximum 16 mm² infiltration over a 10 cm scratch length.
This result provides a measurable indication of how the system performs when the protective surface is compromised, offering insight into real-world durability.
Why the ISO 9227 Salt Rating Matters
The ISO 9227 salt spray rating confirms that SLEEKFENCE™ aluminum fencing systems are engineered to resist corrosion and material degradation in high-salinity environments.
This is particularly important for projects where exposure to salt is unavoidable, including coastal developments and regions with frequent road salting.
For architects, developers, and contractors, this rating supports:
• Confidence in material longevity in aggressive environments
• Reduced maintenance requirements over the lifecycle of the system
• Preservation of architectural appearance in high-visibility applications
• Reliable performance even when surface damage (e.g., scratches) occurs
SLEEKFENCE™ is designed not only to meet performance expectations—but to maintain its visual and structural integrity over time.
Conclusion
The ISO 9227 salt spray performance of SLEEKFENCE™ demonstrates a high level of corrosion resistance under prolonged exposure to salt-laden conditions.
This makes SLEEKFENCE™ aluminum fencing systems a strong choice for:
• Coastal and waterfront properties
• Urban environments exposed to de-icing salts
• Commercial, residential, and institutional applications requiring long-term durability
For projects where environmental exposure is a critical factor, SLEEKFENCE™ provides a balance of performance, longevity, and architectural consistency.

Frequently Asked Questions
What is the ISO 9227 salt spray test?
ISO 9227 is an internationally recognized corrosion testing standard that evaluates how metallic materials perform when exposed to salt-rich environments. It is widely used to assess durability for exterior applications.
Why is salt spray testing important for aluminum fencing?
Salt exposure is one of the leading causes of premature deterioration in exterior metal systems. Salt spray testing provides a reliable benchmark for how well an aluminum fence will perform in coastal regions, urban environments, and areas with heavy road salt use.
Is SLEEKFENCE™ suitable for coastal environments?
Yes. Based on its ISO 9227 test performance, SLEEKFENCE™ aluminum fencing systems are well-suited for coastal and other high-salinity environments where corrosion resistance is critical.
What does “16 mm² infiltration over 10 cm” mean?
This measurement indicates the extent of corrosion spread from a controlled scratch after testing. Lower infiltration values reflect stronger resistance to corrosion beneath the coating.
Does salt spray testing reflect real-world conditions?
Salt spray testing is an accelerated method designed to simulate long-term exposure to salt-laden environments. While conditions vary by project, it is a widely accepted standard for evaluating comparative material performance.
What happens if the fence coating is damaged?
The test result includes evaluation of a controlled scratch, providing insight into how the system resists corrosion even when the surface coating is compromised—an important factor for long-term durability in real-world conditions.
