The particularities of industrial safety padlocks

The safety padlock can be used in different ways depending on its composition, shape and strength. Often “standard” for individuals, it is equipped with various options when it secures industrial products and sites. Here are some examples of safety padlocks and their particularities.

Security seal

The padlock seal is often composed of a wire clasp and a plastic body. While it does not completely block an opening or access, it is nevertheless effective in providing proof of break-in if it is damaged. Seals can also use bar codes to record and track goods equipped with them. Light and practical, it is an excellent alternative to the classic padlock when there is no need to physically block access.

Safety padlock with steel, nylon or aluminum shackle

The security of the padlock can be reinforced by the presence of a hardened steel shackle. It is also possible to choose a nylon body in order to cut off the flow of electrical current between the shackle and the key. The aluminum shackle is used to reduce the total weight of the lock. Finally, the stainless steel shackle provides maximum corrosion resistance.

brass safety padlock

The solid brass lock body and shackle provide numerous advantages. First of all, brass has “anti-spark” properties. It is therefore ideally suited to flammable environments. Second, it is a material that resists corrosion. This provides additional security in the long term.

Small, lightweight and compact padlocks

Their body is made of non-conducting nylon and their shackle is made of aluminum. Perfect for visual identification, they are small in size and available in various colors.

Nylon-coated padlock

Insulating aluminum and/or steel from the body and shackle of a padlock with nylon isolates it from electric shocks. This coverage also reinforces the solidity of the device by improving in particular the resistance to corrosion.

Rolled steel padlock

Applied to the body of the padlock, laminated steel provides excellent protection against rust. It is often used in humid environments. To obtain optimal protection, the ideal is to choose a stainless steel shackle.Options for secure padlocks

Padlock labels

There are consignment/conviction labels, which allow you to display warnings such as “danger” or “property of”, for example.

The keys

Each lock can have a unique key. However, there are plenty of options when it comes to organizing key sets. For example, it is possible to choose a group of padlocks that can be opened with the same key, using a master key. It is even possible to opt for a master key capable of opening several groups of padlocks. For greater security, padlocks are often equipped with a key retention device: it is impossible to remove the key if the lock handle is not properly closed.

Laser engraving

More effective than a label, laser engraving is ideal for naming a lock without taking the risk of the information being erased. Businesses that want to equip themselves with security locks must take into consideration many parameters before validating their purchase. The environment, the weather, but also access to sites and products are all factors that are of paramount importance.
