G80 vs G100 Lifting Chain: What's the Difference?
Chain grade is the single most important number on a lifting chain. G80 and G100 look similar, but the difference in strength changes what you can safely lift. This guide explains both grades and how to choose.
What Do Chain Grades Mean?
The grade number refers to the material strength. A higher grade chain is stronger for the same link size, so you can lift more with less weight, or use a smaller, lighter chain for the same load.
G80 Chain
Grade 80 chain is the standard for overhead lifting and chain slings. It is alloy steel, heat-treated, and widely used with grade 80 fittings and hooks. G80 is the default choice for most lifting operations.
G100 Chain
Grade 100 chain is roughly 25 percent stronger than G80 for the same size. That extra strength lets you use a smaller chain or lift heavier loads. G100 costs more but reduces weight and link size.
Key Differences
| Feature | G80 | G100 |
|---|---|---|
| Strength | Standard | About 25% stronger |
| Cost | Lower | Higher |
| Best for | General lifting | High-capacity or weight-sensitive lifts |
How to Choose
For general lifting, G80 is the proven, cost-effective choice.
If you need more capacity in the same link size, or want a lighter rig, choose G100.
Always match the chain grade to its fittings and hooks; never mix grades.
FAQ
Is G100 stronger than G80?
Yes. G100 is about 25 percent stronger than G80 for the same link size.
Can I mix G80 and G100 components?
No. Chain, hooks and fittings must be matched by grade to keep the system's rated strength.
