What is the Strongest Security Chain?

In our daily lives, the demand for safety protection is increasing day by day. Whether it is the motorcycles, the various cranes on construction sites, or the valuable goods in warehouses, all of them require reliable protection. The security chain, with its excellent strength and reliability, has become one of the most popular and widely used means of protection. So, what kind of security chain is the strongest security chain? This article will provide a detailed explanation for you in all aspects.
Types of the Strongest Security Chain
The strongest security chain can be divided into two major categories based on different usage environments and purposes:
- Anti-theft Security Chain: Mainly used for various locks, such as motorcycles, warehouse doors, etc.
- Industrial Security Chain: Used for lifting, transportation, and the binding of heavy equipment or goods.
The Strongest Security Chain for Anti-Theft
Anti-theft chain is strong in excellent cut resistance, therefore, STRONGEST SECURITY CHAIN not only needs to be made of hard material, but also needs to be able to withstand all kinds of damages including hydraulic shears, angle grinders and so on by using various production processes to improve the strength and adaptability to the environment.
- High Strength Material and Heat Treatment Process
Such as boron steel, manganese steel, etc., the hardness of the security chains that made of these materials can reach HRC 45-55 after heat treatment, much higher than the hardness of ordinary steel chain (HRC 20-30), which can effectively resist the cutting damage of Angle mill and other equipment. - Use Wire Rods of Different Shapes
The wire with square or hexagonal cross-sections can improve the strength of the security chain and increase the difficulty of cutting and destruction. - Welding Process
The strongest security chain requires the use of a higher strength full weld process, ensuring no pores, cracks, or other defects to improve overall strength.

In addition, international certification organizations (such as Sold Secure in the UK) set security chain levels by simulating real theft:
- Sold Secure Diamond: Must resist angle grinder cutting for at least 5 minutes.
- ART 5-Star (Netherlands): Must withstand hydraulic cutter pressure of at least 12 tons and resist angle grinder cutting for at least 3 minutes.
The Strongest Security Chain for Industry

The standard of STRONGEST SECURITY CHAIN used in industry lies in its maximum load capacity, which is measured by tensile strength and breaking tension, we take the lifting chain as an example, this is a kind of welded chain made of alloy steel, which has extremely high strength and working tension:
- G80 Grade: Minimum breaking strength of 800MPa. Typically, these chains have a safety factor of 4:1, but in extreme conditions, the safety factor may be increased.
- G100 Grade: Minimum breaking strength of 1000MPa, able to withstand extreme tension in applications such as large ship anchor chains.
How to Choose the Strongest Security Chain for Different Applications

- For Anti-Theft Applications
A 14-16mm security chain is already the strongest security chain for motorcycle and bicycle theft prevention. Tuohai’s 16mm security chain has been heat-treated and specially surface-treated, can effectively resist angle grinder cutting for up to 5 minutes without breaking. If it is larger, it will be very inconvenient to use. - For Industrial use
In industrial lifting applications, the strongest security chain is the G100 or G120 grade alloy chain, and G80 is the lowest standard. This type of chain can withstand a load of more than 100 tons without breaking, such as the anchor chain of large ships, and has a higher safety factor.
Conclusion
The strongest security chain changes with the application requirements.
For ordinary anti-theft applications, a 14mm security chain certified by Sold Secure can be called the strongest security chain. But for large industrial applications, such as ships and ports, just the alloy chains above G80, such as G100 Chain, G120 Chain, etc., can be called the strongest security chain.
Therefore, when choosing the strongest security chain, you need to consider the strength, cost, and actual application requirements to choose the most suitable strongest security chain.
