When talking about chain used within the rigging industry, graded welded chain is the only appropriate chain. Weldless chain is not permitted for rigging applications. The grade of chain is included in the title of the welded chain ie. Grade 30, Grade 40, Grade 70. The higher the number, the stronger the chain is resistant to bending and breaking.
| Grade 30 | General-purpose chain, the low-carbon chain used in industrial and agriculture applications including load securement, logging, and guard rails. *Not to be used for overhead lifting. |
