Do steel and aluminum carabiners have the same minimum strength rating?

• A. Yes
• B. No
• C. Only steel
• D. Only aluminum

Answer: (A)

The main idea here is that safety ratings are standardized to a common minimum across materials. In our ropes course context, carabiners—whether steel or aluminum—must meet the same minimum strength rating to be approved for use. That means, for the purpose of the course, both types are considered capable of the required minimum load, so they’re treated as having the same minimum rating.

In practice, steel carabiners are inherently stronger, but the published minimum strength that matters for safety certification and usage on the course is set to the same level for both materials. The other options imply that only one material meets the rating or that there isn’t a shared minimum, which isn’t how our safety standards are applied.
