U-Bolt Plates

Add a mounting plate to your U-bolt for a more secure hold at the mounting surface.

Black-Oxide Steel—Black-oxide steel mounting plates have mild corrosion resistance.

Zinc-Plated Steel— Zinc-plated steel mounting plates have good corrosion resistance in most environments.

Galvanized Steel—Galvanized steel mounting plates have better corrosion resistance than black-oxide and zinc-plated steel mounting plates.

Aluminum—Aluminum mounting plates are lighter weight and more corrosion resistant than steel mounting plates, but aren't as strong.

304 Stainless Steel—304 stainless steel mounting plates have excellent corrosion resistance and good chemical resistance.

316 Stainless Steel—316 stainless steel mounting plates have excellent corrosion and chemical resistance.
