Drawing Steel showcases advanced ability to be drawn. It is characterized by less than .05% carbon, making it very soft, easily bent and shaped in the manufacturing process. It is suitable for applications requiring superior drawing capabilities. Kloeckner Metals supplies DS cold rolled, galvanized, and galvannealed.
Deep Drawing Steel is intended for severe drawing applications. Its drawing capabilities are nearly equivalent to that of aluminum 1100. Kloeckner supplies DDS in galvanized and galvannealed formats.
Extra Deep Drawing Steel offers the highest formability and the lowest strength reserved for deep drawing applications. Kloeckner Metals stocks EDDS cold rolled, galvanized, and galvannealed.
Kloeckner Metals supplies 33-SD in cold rolled format.
Kloeckner Metals supplies 33-55 in galvanized and galvannealed formats.

G50 and G80 are double-sided zinc-coated steels commonly used for building products. The amount of zinc coating is measured by the coating weight using the unit ounces per square foot (oz/ft2) and signaled by the numbers 50 and 80. A higher number indicates greater corrosion resistance due to a thicker protective coating. Kloeckner Metals supplies these two grades in galvalume format.
These hot dip galvanized steel grades are intended for applications requiring corrosion resistance and moderate bending and forming capabilities. G90 is growing in popularity in the solar industry.

Prepainted steel is popular across industries for widespread applications including roofs, doorways, and interiors, insulation, automotive, and solar reflective paneling. With nearly an unlimited number of color and texture options, prepainted steel provides superior adhesion and more reliable surface consistency that can be cut, bent, and generally worked without damaging the finished coating. Kloeckner Metals supplies prepainted steel in hot rolled dry, HRPO, cold rolled, galvanized, galvannealed, and galvalume formats.

ANSWER:
Carbon flat roll products undergo a hot or cold rolling process to achieve a flat, rectangular cross section, and are wound into coils with select thicknesses.
Hot rolling steel occurs while the steel is at 1700 degrees Fahrenheit where the steel is malleable enough to be formed flat. Running the hot steel through compression rollers produces a flat-rolled sheet. Then the steel is wrapped into a coil and left to cool. Blemishes and roughness are common as the steel cools. This simple, highly popular manufacturing method benefits applications where a smooth surface quality remains insignificant.
Cold rolled steel involves passing room temperature steel through high pressure rollers. Room temperature steel allows fabricators greater control and consistency while rolling. While the cold rolled steel processing is more extensive when compared to hot rolling steel, the main advantages are a more refined surface character and improved durability.
Once hot or cold rolled, the metal may receive additional treatments to improve surface character, resistance to corrosion, extend longevity, and more.
ANSWER:
It’s typical for oxides to form on the surface after steel is hot rolled and has cooled. In the hot rolled dry process, the dry steel sheet’s oxide surfaces are removed in an acid bath, then rinsed. Unlike HRPO, rolled dry steel is not oiled after it has been rinsed.
ANSWER:
Hot rolled pickled and oiled steel (HRPO) improves protection against corrosion. Pickling steel refers to an acid bath that removes surface oxides on the steel’s surface. Once this oxide film has been removed from the steel, it is rinsed and finished with an anti-rust protective oil coating.
ANSWER:
Cold rolled steel involves passing room temperature steel through high pressure rollers. This allows for greater control and consistency to achieve smooth surface quality and even thickness throughout. However, the processing for cold rolled steel tends to be more extensive when compared to hot rolling steel. The main benefits for cold rolling steel are more refined surface character and improved durability.
ANSWER:
Galvanized steel refers to cold rolled steel that has been hot-dipped in a zinc bath. Galvanization is the process of exposing metal to a zinc bath.
Once removed from the bath, the steel, now coated with zinc, chemically reacts to oxygen in the air. This bonds the zinc to the steel and forms a protective, more corrosion-resistant product. Different thicknesses of this protective zinc coating can be achieved, and are included in the conventional naming system for galvanized metal products. The standard guideline equates a heavier coating with higher durability.
ANSWER:
Galvannealing begins by galvanizing steel. Once galvanized (i.e., placed in a zinc bath), the steel is annealed. Adding this heat treatment results in a zinc-iron alloy coating. The addition of iron hardens the surface, gives it a matte aesthetic, and makes it more scratch resistant than galvanized steel. Galvannealed steel can be painted after the fabrication process. This is one of the main differentiators between galvanized steel and galvannealed steel.
ANSWER:
Galvalume combines zinc, aluminum, and silicon. This combination forms a high-performing protective layering. Cold-rolled carbon steel sheet gets continuously hot-dipped with aluminum and zinc alloys. Galvalume gives the best characteristics of each metal, surpassing the corrosion resistance of galvanized steel by up to four times. It is especially popular for metals used in outdoor metal roofing, metal paneling, and other metal building products.
ANSWER:
Pre-painted metal–also referred to as coil coated metal–is an alternative to post-painting metal that produces a higher integrity, more corrosion resistant top coat of nearly any color imaginable. Pre-painted metal is produced by a highly automated process made possible by accumulators. The cold rolled and galvanized sheet metal is uncoiled at a prescribed rate to receive alkaline degreasing, cleaning, treatment, sealing, curing, and cooling until a paper-thin coating of paint has adhered to the metal. Once the final layer has adhered and dried, the metal can be further processed without risk of damaging the painted top coat. Pre-painted steel or aluminum is very common for metal roofing, the automotive industry, and household appliances.
