They are reversible keys, in some cases even impossible to duplicate without a special authorisation. The locking mechanism is usually double, and the keys also have a special feature to prevent undesired unlocking. In the case of the high security padlock, the main characteristic is that they are made of hardened and tempered steel, in addition to a coating, thus protecting it from rust. We can find high, medium and low security padlocks. This factor is one of the most relevant when selecting the type of padlock we are going to choose, as it will define the degree of security we need. Is what we are going to protect very valuable? And what should we take into account when choosing a padlock? These are some of the factors to consider. The first thing we have to do to decide which type of padlock is ideal for the situation we are facing is to analyse the situation. Their most common uses are to protect access to land, homes, premises, boats, bicycles, valuables, lockers, suitcases, etc. There are different types of padlocks for different needs and situations. Even so, nowadays we can also find the use of other materials, such as aluminium and steel, among others. In terms of material, it is true that some of the materials that were originally used are still in use today. Over the years, the padlock has evolved, improving its security through different locking systems. It was in the year 1000 that this security system as we know it today was called a padlock. Later, in the year 850 in England, padlocks with spring-barbed mechanisms were used. This type of padlock was made of materials such as bronze, silver and brass. We also find the presence of padlocks in China from the 25-220s, which operated with split springs. These padlocks consisted of a box, a fixed sleeve and a bent rod which was inserted to lock and unlock the system. The first padlocks date back to Roman times (500-300 BC). This makes the padlock a really versatile security system. As they are available in various shapes, sizes and materials, they are able to adapt to different situations and needs. The padlock is a very common element in everyday applications and uses. ![]()
