Grade 80 Chain Fittings vs Grade 100 Chain Fittings

Grade 80 and Grade 100 chain fittings refer to different types of high-strength alloy steel chains and related components used in rigging, lifting, and various industrial applications. The grades indicate the strength and durability of the chains, with Grade 100 being a higher strength chain than Grade 80. Let's compare these two grades of chain fittings:

Grade 80 Chain Fittings:

  • Strength: Grade 80 chain fittings are made from alloy steel and are known for their high strength and durability. They are commonly used for lifting heavy loads and are suitable for a wide range of industrial applications.
  • Working Load Limit (WLL): Grade 80 chain fittings have a specific working load limit, which is the maximum load that the chain can safely lift under normal usage conditions. The working load limit is typically marked on the chain fittings.
  • Advantages: Grade 80 chains are strong and relatively lightweight compared to lower grade chains, making them easier to handle. They offer a good balance between strength and weight.
  • Applications: Grade 80 chain fittings are used in various industries, including construction, manufacturing, transportation, and more, where lifting, rigging, and load securement are required.

Grade 100 Chain Fittings:

  • Strength: Grade 100 chain fittings are even stronger than Grade 80 chains. They are designed to handle heavier loads and provide higher tensile strength and greater durability.
  • Working Load Limit (WLL): Grade 100 chain fittings have a higher working load limit compared to Grade 80 chains. This means they can lift heavier loads while maintaining safety.
  • Advantages: Grade 100 chains are particularly well-suited for applications that involve heavy lifting or where space and weight limitations are a concern. They allow for the same lifting capacity with a smaller diameter chain, which can be beneficial in certain situations.
  • Applications: Grade 100 chain fittings are commonly used in demanding industries, such as heavy construction, mining, offshore operations, and other heavy-duty applications where safety and strength are paramount.


When choosing between Grade 80 and Grade 100 chain fittings, several factors should be considered:

  • Load Requirements: Determine the maximum load you need to lift or secure. Choose the grade of chain fitting that provides a sufficient working load limit for your specific application.
  • Space and Weight Constraints: If you're dealing with limited space or weight restrictions, Grade 100 chains might offer an advantage due to their higher strength-to-weight ratio.
  • Industry Standards: Ensure that the chain fittings you choose comply with relevant industry standards and regulations for your region and application.
  • Safety: Safety is paramount. Always follow proper usage guidelines, inspect chain fittings regularly, and consult with experts if you have any doubts about the appropriate choice for your needs.

Both Grade 80 and Grade 100 chain fittings offer high strength and durability, but Grade 100 is designed for more demanding applications where heavier loads and increased strength are required.
