Choices, choices
Steel and aluminum alloy are the two most common materials used for carabiners used in rope access work. Each has its pros and cons in terms of strength, weight, durability, and corrosion resistance.
Steel Carabiners
Steel carabiners are known for their high strength and durability. They are able to withstand heavy loads and frequent use without deforming. However, steel carabiners tend to be heavier than aluminum alloy options.
Aluminum Alloy Carabiners
Aluminum alloy carabiners are lighter weight, making them ideal for applications where weight is a concern. However, they are not as strong as steel and can deform more easily under heavy loads. Aluminum alloy carabiners are more corrosion resistant, especially in wet environments.
Recommendations for Rope Access Technicians
For most rope access work, aluminum alloy carabiners are recommended due to their lighter weight. Brands like Rock Exotica and Petzl offer high quality aluminum alloy carabiners specifically designed for rope access.
Steel carabiners are best suited for applications involving very heavy loads or where durability is critical. They are a good option for rescue work and other demanding tasks where weight is not an issue.

In summary, while steel carabiners are stronger, aluminum alloy options are a better choice for most rope access technicians due to their lighter weight and greater corrosion resistance. High quality brands offer specialized aluminum alloy carabiners designed specifically for rope access work.
