Composite toe and shank boots instead of steel. The steel will conduct cold to your feet. They might not even be needed, soft toes might be fine. Might need to be a half size bigger than normal because:

Layered socks. Thick polypropylene from WalMart work fine. Thin inner socks, polypro if you can stand the feeling, cotton otherwise. Change inner socks at break.

Long underwear bottoms and your work pants should be OK.

Layers for the torso. I always use a vest for one of my layers at work because it keeps my core warm and lets my arms move better.

Hat. A thin beanie, called a “watch cap”. You might need to wear a hardhat and the thin cap that doesn’t cuff will fit under it.
