Production Process

HRC (Hot Rolled Coil)

HRC is made through a rolling process at a high temperature of above 927°C. This process produces steel with a rough and oxidized surface. HRC products themselves usually consist of low or medium carbon (C), iron (Fe), manganese (Mn), and a small mixture of other elements, such as silicon and others.

Use of HRC:

• Structural pipes for piling
• Oil and gas pipes for oil and gas industry projects
• Water pipes for water circulation systems in buildings or water treatment plants

CRC (Cold Rolled Coil)

Unlike HRC, CRC is produced through the cold rolling process of HRC. Rolling is done at room temperature to achieve higher thickness and precision. This process produces steel with tight control of impurities and a smoother surface.

Uses of CRC:

• Mechanical tubes for automotive parts
• Appliance tubes for broom handles or stove components
• Stainless steel pipes for kitchen sets, wheelchairs, and stair railings

Characteristics & Advantages

HRC

• Rough and oxidized surface
• Less precise dimensions
• Advantages: more resistant to deformation

CRC

• Smooth and aesthetic surface
• More precise thickness and dimensions
• Suitable for finishing such as painting and coating
• Easy to mold after heating, ideal for applications with tight tolerances

Conclusion

Each type of coil has its own advantages and disadvantages, depending on the application needs. HRC is suitable for structural applications that require deformation-resistant materials, while CRC is more suitable for high-precision and aesthetic requirements.
