Who It Is For
Buyers Who Specify Grade 80 Links
- Rigging fabricators building custom chain slings and lifting sets
- Lifting service companies replacing worn master links across a fleet of chain slings
- Marine and offshore contractors needing galvanised Grade 80 links for deck and mooring applications
- Steel fabricators and precast plants integrating chain fittings into lifting anchors and rigging points
- Industrial maintenance teams sourcing replacement links for high-duty chain assemblies
Problems Solved
What Grade 80 Links Solve on the Job
- A chain sling missing the correct master link because the size or grade was not in stock at the supplier
- A master link arriving with a plain finish when the application requires corrosion resistance for outdoor or marine use
- A mismatched grade between the chain and the link, leading to a weak point in the lifting system
- No working load limit marked on the link, making it impossible to verify compliance with the lifting plan
- A link with a non-standard size that does not match the chain diameter, causing a loose or unsafe connection
- Small orders for a specific master link pattern being rejected by a forge that only takes bulk production runs

Where Grade 80 Links Are Used
- Connecting two chain segments into a lifting sling on a fabrication yard where the master link must match the chain grade and diameter
- Rebuilding a chain sling on a crane hook where the original master link is worn and needs replacement
- Deck rigging on a vessel where a galvanised Grade 80 master link is required for corrosion resistance
- Lifting a heavy steel beam in a construction site where the master link must handle dynamic loads and remain secure
- Installing a chain anchor point in a temporary structure where a ring connector is used to tie off the chain

Answers
Grade 80 Links FAQ
What is the difference between a master link and a coupling link?
A master link is a specific type of coupling link used to join two ends of a chain. It is often designed with a removable pin or bolt for assembly and disassembly. All master links are coupling links, but not all coupling links are master links.
How do I know which grade of master link to use?
Match the master link grade to the chain grade. For example, use a Grade 80 master link with a Grade 80 chain. Using a lower grade link reduces the overall strength of the chain assembly.
What does WLL mean on a Grade 80 link?
Working Load Limit is the maximum safe load the link is designed to carry. It is calculated by dividing the minimum breaking load by the design factor, which is 4:1 for most rigging hardware unless otherwise stated.
Can I use a Grade 80 link with a Grade 70 chain?
No. The link grade must match the chain grade. Using a Grade 80 link with a Grade 70 chain creates a mismatch that reduces the system’s strength and may violate safety standards.
Do you supply Material Test Certificates for Grade 80 links?
Yes. A Material Test Certificate to EN 10204 3.1 is issued with the batch on request. Every batch undergoes proof load testing and dimensional inspection before release.
Can you custom stamp tonnage and brand on the link?
Yes. Custom tonnage stamping private label marking and custom packing are available. Send the marking layout and pack configuration you need.
What is the smallest order you will accept?
We accept small top-up orders as part of a mixed rigging order. There is no minimum order quantity for Grade 80 links when included in a larger purchase.
