There are four major processes for applying zinc to steel nails.
- Hot Dipping in Molten Zinc, (galvanized nails are double hot-dipped)
- Tumbler or Barrel Hot Galvanizing (also called hot-galvanizing)
- Mechanical Plating (also called peen-plating)
- Electro-Plating (which makes those pretty, shiny nails – often called “EG”)
Hot Dipping in Molten Zinc. (galvanized nails are double hot-dipped).
Hot dipping nails in Molten Zinc is acknowledged by most authorities as the best way to apply a heavy uniform coating to nails. In this process, the nails are completely immersed into a vat of molten zinc, similar to french-frying potatoes. This not only gives an outer coating of pure zinc, but also provides a tenacious inner coating of zinc-steel alloy. Our galvanized nails are further protected by a second dip into the protective zinc to preclude pinholes or imperfections – and to increase the amount of zinc on every nail. This exclusive processing by completely automated equipment insures both a heavy, uniform zinc coating and clean threads for high holding power.
Tumbler or Barrel Hot Galvanizing. (also called hot-galvanizing)
Hot-Galvanized nails (Tumble or Barrel Process) are the type most often produced by big steel mills. Hot-galvanized nails are coated by sprinkling zinc chips on cold steel nails in a barrel, then rotating the hot barrel in a furnace to melt and distribute the zinc.
Mechanical Plating. (also called peen-plating)
Mechanical plated nails, also called peen plated nails, are a relatively new development involving rolling cold nails around in a barrel with zinc dust, tiny glass “BB’s” and an activator fluid. The barrel rotates and the BB’s hammer or peen the zinc dust onto the nails.
Electro-Plating. (which makes those pretty, shiny nails)
Electro-plating of nails is performed by placing them in a basket into an electrolytic solution so that a thin film of zinc is deposited by an electrical current from zinc anodes onto the surface of the nails. electroplated nails are beautiful and shiny, plated nails have good holding power from clean threads, Although they do not have the heavy zinc coating needed to avoid rusting and staining.
