Introduction
A high-quality security chain is one of the simplest and most effective deterrents against theft. Whether you’re protecting bikes, motorcycles, gates, machinery or outdoor equipment, a strong chain paired with a reliable padlock provides robust, visible security.
At English Chain Direct, our Security Chains collection includes everything from lightweight chains for everyday use to heavy duty hardened steel chains for the highest levels of protection. This guide explains how to choose the right chain, what features to look for, and which models best suit your needs.
What Is a Security Chain?
A security chain is a specially hardened chain designed to resist cutting, sawing, prying or attack from bolt cutters and grinders. Unlike a standard link chain, a security chain uses alloy steel treated for exceptional hardness and often features oversized links to make cutting extremely difficult.
Most are used with high-security padlocks or ground anchors for maximum protection. Many chains also include protective sleeves to prevent scratches and corrosion.
You’ll find options in our range such as the Superquad Security Chain 14 mm Sleeve, the Stronglink Heavy Duty Security Chain, and the Quadlink Security Chain — all built for professional-grade security.
Types of Security Chain
Not all security chains are built the same. Below are the main types you’ll find in our collection.
Hardened Security Chains
These chains are heat-treated to increase resistance to cutting tools. They’re ideal for use with padlocks on gates, barriers, motorcycles or plant machinery.
Sleeved Chains
A sleeved security chain, such as the 14 mm Superquad Chain with Protective Sleeve, prevents scratching of paintwork and helps protect the links from moisture and rust. The sleeve also reduces noise when transporting or storing the chain.
Heavy Duty Chains
For maximum protection, heavy duty security chains feature large diameter links — often 10 mm, 12 mm or 14 mm — that resist most hand tools. See our Stronglink Heavy Duty Chain and Superquad Security Chain for top-end strength.
Galvanised and Coated Chains
Some chains, like our General-Purpose Galvanised Chain, offer protection from corrosion for outdoor use while maintaining flexibility for lighter-duty security applications.
Chain and Padlock Sets
For convenience, we also offer chain and lock kits, pairing premium hardened chains with equally strong padlocks. A great example is the Stronglink Chain and Lock Set, perfect for motorcycles, gates or machinery.
How to Choose the Right Security Chain
Choosing the right chain depends on what you’re securing, where it’s stored, and the level of protection required.
1. Identify the Risk Level
For high-value items like motorbikes, quads, and expensive tools, choose a heavy duty chain of 12 mm or thicker. For garden gates, sheds or general storage, a mid-weight hardened chain may be sufficient.
2. Consider the Environment
Outdoor and marine environments require corrosion resistance. A galvanised or sleeved chain will last longer and look better over time.
3. Match the Chain to the Lock
Always pair your chain with a closed-shackle padlock or armoured lock for maximum security. Our Padlocks Collection includes models designed specifically to fit large-link chains like the Superquad and Stronglink.
4. Choose the Right Length
Measure how much chain you need to wrap through or around your object and anchor point. Remember that thicker chains are less flexible — it’s often worth going slightly longer than you think.
5. Look for Quality Indicators
Features such as hardened steel construction, anti-corrosion coating, and sleeving all contribute to long-term performance. Products like the Quadlink Security Chain combine all of these for everyday strength and reliability.
Common Uses and Applications
Security chains are incredibly versatile. Some of the most popular uses include:
-
Motorcycles and Bicycles: Heavy duty sleeved chains like the Superquad 14 mm provide top-tier protection against bolt cutters and saws.
-
Gates and Driveways: Hardened chains such as the Stronglink Heavy Duty Chain are perfect for securing gates, barriers and access points.
-
Tools and Machinery: Shorter chains like the Quadlink Security Chain help lock equipment inside sheds, garages or trailers.
-
Charity Boxes and Cabinets: Light to medium-weight chains such as the Donation Box Chain Set help secure small but important items.
-
Marine and Outdoor Storage: Galvanised chains resist rust, ideal for moorings, docks or damp environments.
Fitting and Maintenance Tips
A strong chain is only effective if it’s used correctly.
-
Anchor securely: Loop the chain through solid fixed points — a ground anchor, wall bracket, or immovable post.
-
Avoid contact with the ground: Keeping the chain off the floor reduces leverage points for cutting.
-
Minimise slack: The tighter the chain, the harder it is to attack.
-
Keep it clean: Wipe down periodically and apply light oil to prevent corrosion.
-
Inspect regularly: Replace any chain showing signs of damage, rust or wear.
For a complete setup, pair your chain with a ground anchor and closed-shackle padlock from our Security Accessories range.
Frequently Asked Questions
What is the strongest security chain?
Our Stronglink and Superquad chains are among the toughest available, featuring hardened steel construction and extra-thick links for exceptional cut resistance.
Can I use a security chain outdoors?
Yes — many of our chains, like the 14 mm Sleeved Superquad, are designed for outdoor use with weatherproof coatings and sleeves.
Do I need a special padlock for security chains?
Ideally, yes. Use a high-security padlock with a shackle thick enough to fill the chain link but still allow smooth locking.
Are sleeved chains better?
Sleeved chains protect both the chain and your property’s surface from scratches, and they also help reduce rust formation.
What’s the best chain for motorcycles?
We recommend the Superquad 14 mm Sleeved Security Chain or the Stronglink Heavy Duty Chain, both designed to resist bolt cutters and grinder attacks.
