Weapon durability

[Nelris]

I’m fairly new to STW, been playing BR for some time now and bought a bundle about a year ago and decided it was time to get into the pve section. Seems to be a pretty fun game, though on my first match a veteran just handed me some golden weapons which is pretty nice. My only concern is what can I do about durability? Is there way to repair it since I imagine once it’s gone to 0 the weapon is gone?
