This discus lock from Brinks is made of stainless steel from top to bottom, and this includes both the body and the shackle. Stainless steel makes the lock thick and heavy-duty, providing a lot of protection towards impacts, sawing, and prying. 

Also, the rounded design helps to provide the shackle with minimum exposure, and it makes it hard for thieves to get good leverage on it. 

The fact that this lock is made of stainless steel also makes it resistant towards inclement weather, wet, hot, or cold. It comes complete with a rubber cover to minimize exposure to the elements, and it works great for indoor and outdoor applications.
