What Is The Best Padlock To Defend Against Forced Entry and Theft? 

Padlocks are an extremely versatile piece of equipment which can be used for securing personal property against theft, vandalism, unauthorised use and forced entry. At Security 201, our experienced staff are able to advise and supply the right size model, locking mechanism and design features to suit your requirements.

We stock a range of Banham padlocks, all of which are designed to offer the utmost protection from attack and natural corrosion. Furthermore, they use the patented Banham dimple key and registration system, allowing you to restrict who can duplicate the keys. These padlocks can be made to operate on the same key as any Banham Door Lock.

But beyond a brand name, what should you look for from a high security padlock?


How big should a padlock be?

Unfortunately, there is no one-size solution; the best padlock will be the one which is the appropriate size to secure the item in question. Padlock size is simply one of a variety of concerns to consider—from the material from which the body is constructed to the type of shackle itself. However, there are also a range of padlock body shapes beyond the standard, recognisable padlock design, which best suit certain applications.

For example, anvil locks are commonly used to provide an additional level of protection to security shutters, whilst people frequently purchase circular padlocks as a method of locking sheds and outhouses. These two also have extremely short shackles, which make them difficult for any intruders to cut open.


What metal is the padlock made from?

There are four main materials which the body of a padlock is usually made from:

  • Solid brass

Padlocks made of solid brass are the least sturdy, due to how soft the metal is. Solid brass padlocks are cheap to manufacture and consequently sold equally cheaply. This means that they can be drilled open easily, so they are consequently not recommended for protecting your valuables.


  • Solid steel alloy

Solid steel padlocks are far tougher than brass padlocks, involving far more work to manufacture and consequently retailing for higher prices. These locks have been treated to minimise rust, as well as to make them more difficult to pick or drill.

Steel is also the metal used for the top layer of an armour-encased padlock, the interior of which is made from solid brass. By reinforcing this weaker material with the sturdier steel casing, it renders it harder for an intruder to drill the lock open and offers a greatly improved protection in comparison with a regular solid brass padlock.


  • Laminated steel

Whilst both are made of steel, laminated steel padlocks are made from separate sheets of steel which have been pressed together, as opposed to a solid block of metal. Consequently, these are cheaper to make and sold at lower cost, and do not offer the same level of high security due to the tops of their fastening rivets being left bare, making them easy to drill.


  • Pressed steel

A pressed steel padlock is a more secure version of laminated steel padlocks, being made up of only two sheets of steel rather than several. These two sheets are then welded around the shackle, which has two separate locking points, making it one of the best padlocks for general security purposes.

For further reinforcement and weather resistance, a casing of zinc, chrome or plastic is also recommended on any bare padlock to prevent rust or corrosion.


What should I look for from a padlock shackle and locking mechanism?

The main rule when it comes to padlock shackles is that the thicker the shackle itself, the more secure it will be. Likewise, a longer shackle will make it easier to cut open compared with a shorter one. High security padlock shackles will be made from hardened alloy steel, which is reinforced against being sawn or cut open. Stainless steel shackles are also available, in both hardened and unhardened makes, and are often applied to padlocks used for garden sheds and other outdoor buildings.


The locking mechanism of the best padlocks will have at least four pins. These are contained within the body of the padlock itself and are the feature which offers the main mechanical security of the padlock. The pins determine the number of key differs for the padlock; this term is used to describe the number of discrete key patterns that particular lock can generate, meaning that the higher the number of key differs, the better the padlock.
