Heavy lifting at work advice

Hey, recently I've started to have to do a lot of heavy lifting at work and it's kinda messed up my lower back. I was wondering if anyone has any advice on maybe back support or something that would be appropriate?

A lot of them on Amazon look like cheap garbage (who would have guessed) so if anyone has any advice on some kind of back support for heavy lifting, that would be much appreciated.

My form is decent and I used to gym, but it's still pretty heavy solo lifting, and the lifts are a bit awkward too which is why I feel like maybe I need a support just help prevent any damage.
