Flat Rolled Steel Products
Curtis Steel carries a full line of sheet and coil ranging in thickness from ¼” to 30 gauge. Products include Galvanized, Cold Rolled, Galvannealed, Bonderized/Phosphatized, Galvalume, Electrogalvanized, HRP&O, and Stainless. While we maintain a large inventory of “stock sized” sheets and coil on the floor available for immediate pick-up or next day delivery, our in house processing equipment also enables us to produce custom sizes quickly and efficiently. With no order too small, and no order too large, Curtis Steel welcomes the opportunity to meet all your flat-rolled steel needs.
Galvanized sheet or coil is defined as a carbon steel sheet coated with zinc on both sides. Continuous hot dipping or electro-galvanizing are the two processes used to produce galvanized sheet and coil.
Cold Rolled Steel
Cold Rolled Steel is a mill product made with a high degree of gauge accuracy and uniformity of physical characteristics. The deoxidized finish gives an excellent base for paint, lacquer, and enamel.
Galvannealed Sheet is carbon steel sheet coated with zinc on both sides. Immediately as the strip exits the coating bath, the coating is subjected to a heat treatment that converts it to a zinc-iron alloy.
Bonderized steel is galvanized steel put through a phosphate bath and chromate dry. This produces the dull grey color characteristic which provides an excellent "primer" for painting applications.
Hot Rolled Steel (HRP&O)
Hot rolled steel is an all purpose steel product used for roll-formed shapes, pipe, tubing, industrial storage racks, automotive and other stampings, air compressor housings, and much more.
Electro galvanized (EG) sheet is manufactured by electroplating a pure zinc coating on a carbon steel sheet and coil. This coating process applies the coating with an exceptionally uniform thickness.
Galvalume Steel Sheet is carbon steel sheet coated with aluminum-zinc alloy by a hot dip process similar to galvanizing. The nominal coating composition is 55% aluminum and 45% zinc.
The alloy's metallurgical characteristics are established primarily by the nickel content, which also extends resistance to corrosion. Carbon is held at a level that is satisfactory for most applications.
