General Info About CS Type A

CS Type A is a commercial galvanized cold rolled, low-carbon steel. It is intended for mild forming and bending. This carbon flat roll product designation suits projects where strength is more important that surface character, and where some amount of formability and corrosion resistance might be beneficial. Kloeckner Metals stocks cold rolled CS-A, galvanized CS-A, galvannealed CS-A, and galvalume CS-A.

More Details About CS Type A

  • Advantages/Disadvantages

    Commercial Steel Type A is an economical steel that offers strength and formability. It offers strengths between 25 and 55 psi (170-380 MPa) with elongation upwards of 20%. It also shows good resistance to corrosion. One of the main disadvantages is that this steel is not intended for applications requiring a smooth, pleasant surface finishing character.

  • Industries

    This commercial galvanized cold rolled, low-carbon steel is seen in many industries. As a designation for a grade of steel that is suitable for moderate forming processes, many industries might use CS-A for unexposed applications where good strength, corrosion resistance, and formability are needed. This may include architectural applications, building products, general construction, and others.

  • Applications

    CS-A is intended for moderate forming applications. You might see it in building materials for commercial and residential structures, including houses, canopies, carports, schools, and stores. Galvalume CS-A is used for metal roofing.

  • Machining

    CS-A can be machined.

  • Welding

    CS-A can be welded.

  • Heat Treatment

    CS Type A is heat treatable.

More Details About Each CS Type A Steel Product

  • Cold Rolled CS-A

    This carbon flat roll product is roll-formed at room temperature. It does not have any additional processing or heat treatment.

  • Galvanized CS-A

    This standard commercial steel format is first cold rolled and then exposed to a molten zinc bath. This improves corrosion resistance.

  • Galvannealed CS-A

    CS Type A steel that undergoes additional heat treatment has improved hardness and ductility, as well as better resistance to stress and cracking.

  • Galvalume CS-A

    Galvalume offers the most protection. By combining cold rolled steel, aluminum, silicon, and zinc, galvalume CS-A offers enhanced toughness, strength, self-mending properties, and improved corrosion resistance that surpasses both galvannealed and galvanized CS-A steel. CS-A galvalume is most commonly used for building products, including roofs, walls, and trim among other applications.

Frequently Asked Questions

  • What is the difference between galvanized and galvannealed CS-A?

    ANSWER:

    Commercial Steel Type A can be either galvanized (zinc-coated) or galvannealed (zinc-iron coated).

    To determine whether the additional heat treatment will benefit a desired project, consider the importance of surface finish quality, paintability, lifespan, and level of corrosion resistance.

    As a rule of thumb, annealing galvanized steel (i.e., galvannealed steel) will extend the life of the steel and improve corrosion resistance. Where galvanized steel takes on a shiny or spangled characteristic, galvannealed steel will have a duller quality that can be painted after fabrication.

  • What is the difference between CS-A and CS-B?

    The two main differences between these two commercial steels are the amount of carbon in their chemical composition (which indicates a difference in strength) and the formats in which they are available.

    CS Type B has a wider range of carbon content – both higher and lower than that of CS type A. This leads CS-B to show higher strength levels, typically around 205 to 380 MPa. CS Type B is available in hot rolled dry, hot rolled picked & oiled, cold rolled, galvanized, galvannealed, and galvalume formats. CS Type A is not available in hot rolled dry or HRPO formats.

  • What is the chemical composition of CS Type A?

    CS Type A has a chemical composition of carbon, phosphorous, manganese, sulphur, and iron.
