Hot Rolled
Hot Rolled, pickled, and oiled coil or sheet steel that has been descaled of oxide film by either a chemical method, mechanical method, or a combination of both and oiled to help retard corrosion during storage and after descaling. "HRPO" is available in various gauges, widths, and cut lengths or coil.

Cold Rolled
Cold Rolled, commercial quality sheet or coil steel supplied for either exposed or unexposed applications where bending, welding, forming, or moderate drawing is involved. "CRCQ" is available in coil, sheet or strip formed with various gauge ranges, widths, and hardness.

Electro Galvanized
Electro Galvanized sheet steel in coil and cut lengths that is zinc coated by electro-deposition for a light or thin coated mass. This product is manufactured for use as formed or miscellaneous parts where corrosion resistance is necessary as opposed to an uncoated sheet.

Hot Dipped Galvanized
Hot Dipped Galvanized sheet or strip steel bathed in a molten solution containing not less than 98% pure zinc to uniformly coat for corrosion resistance. The coating is not intended to withstand outdoor exposure without chemical treatment or painting. Sheets are produced as commercial quality, drawing quality, drawing quality special killed, structural, physical quality, and are available in regular spangle, minimized spangle, and zinc-iron alloy.

Aluminized
Aluminized is a type 1 and is hot dipped coated with an aluminum-silicon alloy (5%-11%) silicon for better adherence. This product is intended for heat-resisting applications and where corrosion resistance and heat are involved.

Galvanneal
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

Galvanneal, a Hot Dipped Galvanized Steel can be used rather than Cold Rolled Steel with factory applied primers. Galvanneal was developed for the automotive industry by the steel mills to combat the ravaging effects of corrosion most common on vehicles in the 1960's. Most automobile manufactured today do not rust as quickly as older vehicles because automobile manufacturers today uses Galvanneal or a sister product Galvalume for body & body parts.

Paintable Galvanneal is a Hot Dipped Galvanized specially processed steel that receives a mill coating of chromate and phosphate at the steel mill to ensure the maximum in finish paint adhesion and low maintenance operation.

Independent laboratory testing to strict ASTM test criteria has proven that Galvanneal Steel outperforms traditional cold rolled and factory primed painted with regard to corrosion resistance and finish paint film adhesion.
