Galvanized Steel
Steel coated with a thin layer of zinc to provide corrosion resistance in underbody auto parts, appliances, metal buildings, or storage tanks. Sheet steel normally uses cold rolled but can use hot rolled as a base prior to the galvanizing stage.

Hot-Dipped
Steel is run through a molten zinc coating bath, followed by an air stream "wipe" that controls the thickness of the zinc finish.

Continuous Sheet Galvanizing
A continuous process used to produce a zinc coating on steel sheet by immersion in a bath of molten zinc.

Galvanized Plus

Galvanized Plus begins with our standard high-quality bare galvanized sheet and goes a step further. As a final step in our hot-dip coating process, a very thin acrylic coating is applied to both sides of the sheet using a sophisticated reverse roll coater. This acrylic coating eliminates the need for conventional chemical treatment and vanishing oil.

 

Key advantages of Galvanized Plus are:

  • Galvanized Plus can be roll formed or fabricated in other mild forming operations in the dry condition with no vanishing oil applied in our coating line or at the forming line.
  • Galvanized Plus building panels will be delivered to the jobsite dry, with no vanishing oil on the surface. For other applications, the formed parts will be dry, with no post forming cleaning required to remove residual oil.
  • Galvanized Plus resists fingerprinting and smudging during handling and installation.
  • Galvanized Plus provides excellent resistance to storage stain and transit corrosion.
  • Galvanized Plus provides a bright appearance which will weather uniformly.

Galvanneal Steel

Galvanneal is a hot-dip coated sheet product in which the zinc coating has been changed into a zinc-iron alloy coating for improved paintability. This is done in the hot-dip process by taking the zinc-coated sheet as it leaves the bath of molten zinc and immediately subjecting it to a heat treatment that causes the zinc to alloy with the iron and become a zinc-iron alloy coating. Galvanneal has a dull matte appearance compared with the shiny bright surface of hot-dip galvanized. This matte surface is excellent for painting. In fact, Galvanneal is recommended only for painted applications.

The iron-zinc alloy coating is harder and more brittle than the soft zinc coating of hot-dip galvanized. This harder coating is more resistant to scratches during handling, but also may show a greater tendency toward "powdering" of the coating during difficult forming operations. Careful process control during the production of Galvannealed coatings combined with proper forming practices during part fabrication can minimize the powdering and achieve excellent results.

Electro galvanize

Zinc plating process whereby the molecules on the positively charged zinc anode attach to the negatively charged sheet steel. The thickness of the zinc coating is readily controlled. By increasing the electric charge or slowing the speed of the steel through the plating area, the coating will thicken. Zinc-nickel alloy coatings may also be applied.
