ALLWIN offers locking systems and lock cylinders for different clients’ needs. Whether in public institutions, commercial or residential, the locking system plays an important role in security and privacy.


Next, we will briefly introduce two common locking systems.


The deadbolt is a locking mechanism which provides stronger protection through its unique design.
When a door is closed with a deadbolt lock, there will be a solid steel cylinder stuck deep inside the door frame. Therefore, deadbolts can easily resist any physical attacks from people with bad intentions.


The mortise lock is a strong lock often used on security doors. This complicated lock system has recently become common in commercial and residential buildings in the United States and Europe.
