Corrosion is one of the most challenging issues facing industries that rely on fastening solutions. Fasteners exposed to harsh environmental conditions, such as construction, roofing, and marine applications, are particularly vulnerable to corrosion. That’s why understanding the different corrosion classes is crucial to choosing the right fasteners for your projects.
At Engineering Edge (Singapore), we specialize in producing high-quality fasteners designed to withstand various levels of corrosion, and we understand that selecting the right product requires in-depth knowledge of corrosion classes. Corrosion classes are a standardized system used to categorize the severity of corrosion exposure based on environmental factors like humidity, salinity, and temperature. By selecting the right fasteners for each corrosion class, businesses can avoid costly repairs and improve the longevity of their structures.
Class 1 - Very Low: Fasteners intended for indoor environments with low humidity and minimal risk of corrosion, such as heated buildings with clean atmospheres. Examples include offices, shops, schools, and hotels.
Class 2 - Very Low: Environments with low pollution levels, typically found in rural areas or unheated buildings where condensation may occur, such as depots and sports halls.
Class 3 - Medium:Environments with urban or industrial atmospheres, moderate sulfur dioxide pollution, or coastal areas with low salinity. This class also includes production facilities with high humidity and some air pollution, such as food processing plants, laundries, and breweries.
Class 4 - High: Industrial environments and coastal areas with moderate salinity, including chemical plants, swimming pools, coastal shipyards, and boatyards.
Class 5 - Very High: Industrial environments with high humidity and aggressive atmospheres, as well as coastal areas with high salinity. Includes buildings or locations with near-constant condensation and extreme exposure to moisture.
Class 5 - Extreme: Offshore environments with high salinity, industrial areas with extreme humidity and aggressive atmospheres, as well as subtropical and tropical climates.
CORROSHIELD® fasteners are designed with advanced coatings that offer superior corrosion resistance, ensuring long-term durability even in extreme environments. Whether your project requires Class 1 or Class 4 fasteners, CORROSHIELD® products are engineered to provide unmatched protection against rust and wear.
When selecting fasteners for your projects, it’s important to consider the corrosion class of the environment. Fasteners used in higher-class environments, such as marine or industrial areas, should be made of materials with high corrosion resistance, like stainless steel or specialized coatings. CORROSHIELD® fasteners meet these requirements, providing reliable solutions for construction, roofing, and cladding applications.
Understanding corrosion classes and choosing the right fasteners for your specific needs is critical for ensuring the longevity and integrity of your structures. At Engineering Edge, we’re committed to providing fasteners that meet the highest standards of quality and performance, no matter the environment.
