If you want to buy padlocks to secure doors, gates, trailers, storage areas and other possessions, then there are lots of choices. For light security requirements, you can use small brass padlocks with either a key or a combination. These are excellent for tool boxes and lockers, as they are strong and easy to use every day. If you’re looking for high security padlocks, you could buy industrial locks which are very tough and resistant to tampering. Many padlocks that you might buy are rust resistant and weatherproof and come in either long or short shackles. You could buy padlocks made from steel, brass, aluminium or laminated material.
