Welded chains are widely used in industries requiring strength, durability, and safety. The two most common types are G80 and G100 chains, which serve different lifting, hoisting, and securing functions. Learning their applications, differences, and ideal use cases helps in selecting the right chain for the job.
1. Overview of G80 and G100 Chains
What is G80 Chain?
G80 chains are made from high-strength alloy steel and had heat treated for enhanced durability. The “G” stands for Grade, and 80 refers to the chain’s minimum tensile strength of 80 kN per link. G80 chains are widely used in industrial lifting and hoisting applications where moderate to heavy loads need to be handled safely.

What is G100 Chain?
G100 chains are an upgraded version of G80 chains, offering higher tensile strength (100 kN per link). These chains are also made from high-strength alloy steel but incorporate additional nickel, chromium, and manganese elements for greater durability and load-bearing capacity.

2. Applications of G80 and G100 Chains
G80 Chain Applications
G80 chains are strong and flexible, making them ideal for various industries:
·Construction: Lifting steel beams, concrete blocks, and heavy machinery.
·Marine & Offshore: Used for anchor chains and mooring systems.
·Mining: Handling and lifting mining equipment.
·Logistics & Warehousing: Cargo handling, lifting, and securing loads.
·Agriculture & Forestry: Used in logging and farming equipment for load restraint and hauling tasks.
G100 Chain Applications
G100 chains provide higher strength and enhanced load capacity, making them suitable for:
·Heavy-Duty Lifting: Industrial lifting in construction, mining, and manufacturing.
·Offshore & Marine: Mooring systems and anchor chains for oil rigs and ships.
·Cranes & Hoists: Lifting extremely heavy objects in industrial environments.
·Automotive & Aerospace: Used for lifting aircraft components and heavy machinery parts.
·Military & Defense: Often used in high-load applications requiring superior safety.
- Key Differences Between G80 and G100 Chains
Feature | G80 Chain | G100 Chain |
Strength | 80 kN per link | 100 kN per link |
Material | Alloy steel (20Mn2 25MnV) | High-strength alloy steel (8620D) |
Load Capacity | 500 kg – 63,000 kg | 600 kg – 39,300 kg |
Diameter | 4 mm – 45 mm | 4 mm – 32 mm |
Surface | Self color Black oxided Plastic power coated Black Electrophoresis | Self color Black oxided Plastic power coated Black/Blue Electrophoresis |
Packing | Steel drums Plastic pail Wooden box | Steel drums Plastic pail Wooden box |
Cost | More affordable | More expensive due to higher strength |




- Choosing the Right Chain for Your Needs
·For general lifting and secure load handling, G80 chains are a reliable choice.
·For extremely heavy loads requiring extra strength and durability, G100 chains are preferred.
·For marine and offshore applications, both chains work, but G100 offers better performance in high-load conditions.
·Cranes, hoists, and heavy machinery lifting benefit more from G100 chains due to their higher load-bearing capacity.
·Cost-sensitive projects may opt for G80 chains as a more budget-friendly solution without compromising safety.
5. Industry Standards and Certifications
To ensure safety, G80 and G100 chains must comply with international regulations:
·ISO 3076: Specifies the properties of welded lifting chains.
·DIN EN 818-2: European standard for Grade 8 and Grade 10 lifting chains.
·NACM1996/ NACM2010/ NACM2016 : U.S. safety standard for hoisting and lifting chains
·DIN 5687/DIN 5688: German standard governing quality and load capacity requirements.

6. Maintenance and Safety Tips for G80 and G100 Chains
To ensure longevity and optimal performance, proper maintenance is essential:
·Regular Inspections: Proof load test for all chain link and random breaking load test, Check for cracks, wear, and deformations before use
·Lubrication: Apply anti-corrosion grease to prevent rust.
·Storage: Keep chains in a dry, controlled environment to avoid moisture damage.
·Proper Load Handling: Never exceed the working load limit (WLL) specified for the chain.
·Replacement: If signs of damage appear, replace the chain immediately to prevent accidents.

Conclusion
G80 and G100 chains are essential for lifting, hoisting, and securing heavy loads. While G80 chains provide a balance of strength and flexibility, G100 chains are designed for more demanding, heavy-duty applications. Selecting the right chain ensures efficiency, safety, and reliability in various industrial environments. For applications that require maximum strength, durability, and enhanced safety, G100 chains are the best choice. However, G80 chains remain a cost-effective, versatile option for everyday lifting and hoisting needs.
By understanding the differences, applications, and industry standards, businesses can make informed decisions and optimize their lifting operations for safety and performance.
