High Security Padlocks | Heavy Duty & ABS Padlocks
Our range of high security padlocks is built for environments where standard locks simply aren’t enough. Designed to resist cutting, drilling, picking and physical attack, these heavy duty padlocks provide dependable protection for commercial, industrial and high-risk applications.
Whether you're securing gates, roller shutters, warehouses, storage units or high-value equipment, choosing a high security padlock significantly reduces vulnerability to forced entry.
What Makes a Padlock “High Security”?
A true high security padlock goes beyond basic locking mechanisms. Key features typically include:
Hardened steel or reinforced alloy bodies
Anti-drill and anti-pick cylinders
Hardened boron steel shackles for anti-cut resistance
Precision key systems
Weather-resistant coatings for outdoor use
If asset protection is critical, upgrading to a high security ABS padlock provides superior strength and durability compared to standard padlocks.
ABS High Security Padlocks
This collection includes and will continue expanding with a full range of ABS high security padlocks, engineered for strength, reliability and resistance to attack.
Available in multiple sizes and shackle configurations, ABS padlocks are ideal for:
Industrial gates and perimeter fencing
Commercial units and warehouses
Shipping containers and storage facilities
Garages and roller shutter doors
Construction sites and high-value equipment
Their solid body construction and hardened shackles make them a trusted solution for demanding environments.
Heavy Duty Padlocks for Outdoor & Commercial Use
Many of our heavy duty high security padlocks are suitable for outdoor use, offering corrosion resistance alongside enhanced physical security. For exposed locations or high-traffic access points, choosing a hardened, attack-resistant padlock is essential.
Choosing the Right High Security Padlock
When selecting your padlock, consider:
Required shackle clearance and diameter
Indoor or outdoor exposure
Keyed alike or keyed different options
Required security level

Hardened boron alloy shackles, closed-shackle bodies that deny bolt croppers a purchase, anti-drill and anti-pick cylinders, and independent certification — Sold Secure ratings or CEN grades. Body size alone means little; the shackle material and the test rating are what stop an attack.
Match the rating to the risk: Sold Secure Silver suits sheds and garden gates, Gold suits vans, containers and commercial gates, and closed-shackle Gold or Diamond suits high-value storage. Always pair the padlock with an equally strong hasp — a Diamond padlock on a flimsy hasp protects nothing.
Sold Secure is an independent UK testing house operated with the Master Locksmiths Association. Products are attack-tested with real tools and rated Bronze, Silver, Gold or Diamond by the time and equipment needed to defeat them. It's the most trusted padlock benchmark for UK insurers.
Yes — many of our padlock ranges offer keyed alike sets so one key operates every padlock on your site, van and gates. It's a big time-saver for tradespeople and anyone running multiple secured areas.
Outdoor-rated models feature stainless or marine-grade internals, drainage and covered keyways for year-round exposure. For coastal or permanently outdoor use, choose a weatherproof-rated body — a corroded cylinder fails long before the shackle does.
