Bending Steel Ratings

This page lists many common sizes and types of bars, bolts, etc that are used in Grip Sport steel bending as well as the poundage that they have rated in direct testing.

Just a reminder that all steel is not the same and can vary in strength from batch to batch. This is especially true in 1018 CRS and Grade 2 bolts. Grade 5 and Grade 8 bolts will be much more consistent but can also vary.
