Choosing between Grade 80 and Grade 100 lifting chains isn’t always straightforward and getting it wrong has real consequences for load capacity, worker safety, and legal compliance.
Grade 80 and Grade 100 chains are the two most widely used options across UK construction, warehousing, manufacturing, transport, and heavy engineering. Both are approved for overhead lifting, manufactured from heat-treated alloy steel, and meet EN 818 standards.
Even so, they are built for different lifting demands, one suited to routine warehouse work, the other to offshore lifting or heavy steel handling. The right choice depends on the load, working conditions, and how frequently lifts are carried out.
This article covers the key differences between Grade 80 and Grade 100 lifting chains and where each performs best.
Why Chain Grade Matters
Chain grade is a measure of strength and lifting performance, not a general indicator of product quality.
A higher grade delivers more load capacity from the same chain diameter, which affects the working load limit and the overall sling configuration.
Poor chain selection creates serious problems. A chain rated below the required load can fail under stress, while one that is unnecessarily heavy will slow down rigging work and increase physical strain over long shifts.
Chain markings also carry legal significance under UK lifting regulations. Every lifting chain should display the grade, working load limit, and manufacturer details, a requirement that forms part of LOLER compliance and supports accurate inspection records.
Grade 80 Lifting Chain
Grade 80 lifting chain has been used across UK industry for decades and remains one of the most trusted options for overhead lifting and rigging work.
Manufactured from heat-treated alloy steel, it is designed for use in lifting slings and a broad range of industrial lifting applications. Construction firms, warehouses, transport companies, recovery operators, and agricultural businesses use Grade 80 chains daily across a wide range of applications.
The reason is straightforward: Grade 80 handles the majority of industrial lifting jobs reliably, without excessive cost.
A correctly rated Grade 80 sling provides sufficient lifting capacity for routine industrial work
and performs reliably under repeated use in demanding conditions.
Heat resistance is another advantage. Grade 80 chains are tempered at higher temperatures during production, which helps them retain their strength in high-heat environments such as foundries, steel plants, and fabrication workshops.
Cost is also a factor. Grade 80 chain is widely available and straightforward to replace, and businesses running large lifting equipment stocks often remain with it because long-term replacement costs stay manageable.
Grade 100 Lifting Chain
The Grade 100 chain is engineered for higher-capacity lifting work, using a stronger alloy steel composition and a more advanced heat treatment process.
The most significant difference is strength. A Grade 100 lifting chain delivers around 25% more working load capacity than a Grade 80 chain of the same diameter.
That extra strength means smaller chain sizes can handle the same load, resulting in lighter sling assemblies that are easier to position and move throughout the shift.
This is particularly relevant where lifting takes place continuously throughout the day. Offshore operations, heavy fabrication, mining, quarrying, and large precast concrete projects frequently specify Grade 100 chain because lighter assemblies reduce physical fatigue across long shifts.
Grade 100 chain also offers superior abrasion resistance. In demanding environments where chains are subject to regular contact with rough surfaces, this can meaningfully extend service life and reduce replacement frequency.
For lifting teams working with heavy loads every shift, that combination of increased strength and reduced sling weight can make a genuine difference to day-to-day handling efficiency.
The Main Differences Between Grade 80 and Grade 100
Strength
Grade 100 chain delivers approximately 25% more lifting capacity than Grade 80 at the same chain diameter.
This allows lifting teams to use smaller chain sizes while still meeting the required working load limit, providing greater lifting headroom in high-capacity jobs without stepping up to larger, heavier assemblies.
That said, the Grade 80 chain provides more than adequate strength for the majority of everyday lifting tasks across warehouses, transport yards, and construction sites.
Weight and Handling
Because the Grade 100 chain carries more load at a smaller diameter, sling assemblies are correspondingly lighter.
Lighter lifting gear is easier to handle during repeated rigging operations, reducing the physical effort required to move and position assemblies throughout the shift.
Reduced sling weight also eases the load on crane hooks, shackles, and other rigging components during operations.
Grade 80 chain remains the practical choice where reduced assembly weight is not a primary operational requirement.
Cost
Grade 100 chain carries a higher unit cost, reflecting the stronger alloys, tighter manufacturing tolerances, and more rigorous testing involved in its production.
For moderate lifting work, the higher cost may not provide enough real benefit. Many businesses continue using Grade 80 because it gives reliable lifting performance at a lower price.
Grade 80 also costs less to replace as part of ongoing inspection and maintenance programmes.
Safety and Inspection
Both Grade 80 and Grade 100 chains are safe for overhead lifting when used correctly and inspected properly.
Safe lifting depends on more than chain grade. Inspection routines, operator training, and correct load control matter just as much.
Chains should be inspected before each use for cracks, stretched links, corrosion, gouges, and heat damage. Shock loading and incorrect rigging angles are among the most common causes of premature wear and chain failure.
Inspection markings must always remain legible. Any chain where the grade or working load limit cannot be clearly identified should be removed from service immediately.
Proper storage also helps extend chain life. Dry storage conditions and clean handling reduce corrosion and unnecessary wear.
Which Chain Grade Fits Best?
Grade 80 lifting chain works well for general construction lifting, warehousing, transport and recovery, farming, and standard industrial rigging work. It gives reliable lifting strength at a manageable cost.
Grade 100 chain becomes a better fit when lifting jobs involve very heavy loads, frequent rigging work, or harsh environments that create higher chain wear.
Mining operations, offshore lifting, heavy fabrication yards, ports, and large concrete lifting projects often benefit most from Grade 100 chains.
Neither chain is automatically better. The correct choice depends on lifting limits, work conditions, lift frequency, and operating budget.
Final Thoughts
The difference between Grade 80 and Grade 100 lifting chains is not only about strength. It is about using the right chain for the work being carried out.
Grade 80 delivers reliable lifting performance for a wide range of industrial jobs. Grade 100 provides extra lifting capacity and lighter assemblies where demanding operations require it.
Correct chain selection helps keep lifting operations safe, compliant, and cost-effective over the long term.
