Ankena Commodities LLC exporting CR and HR coils from our manufacturing partners in China and Indonesia following global standards and customer requirements suitable for various applications in industries such as construction, automotive, and manufacturing. In summary, the choice between CR and HR coils depends on the specific requirements of the intended application, considering factors such as surface finish, dimensional accuracy, strength, and formability.

CR (Cold Rolled) and HR (Hot Rolled) coils are both types of steel coils that undergo different manufacturing processes, resulting in distinct characteristics suitable for various applications in industries such as construction, automotive, and manufacturing. Here’s a short description of each:

1. CR Coils (Cold Rolled Coils):
   • Manufacturing Process: Cold rolling involves passing hot-rolled steel through a series of rollers at room temperature to achieve a thinner and smoother product.
   • Surface Finish: Cold-rolled coils have a smoother and more polished surface compared to hot-rolled coils.
   • Dimensional Accuracy: Cold rolling provides tighter tolerances and precise dimensions, making CR coils suitable for applications requiring high precision.
   • Strength and Hardness: While CR coils generally have a higher strength and hardness than HR coils, they may be less ductile.
2. HR Coils (Hot Rolled Coils):
   • Manufacturing Process: Hot rolling involves heating steel above its recrystallization temperature and passing it through rollers to shape it. The process results in larger thicknesses compared to cold rolling.
   • Surface Finish: Hot-rolled coils have a rougher surface texture due to the rapid cooling process after rolling.
   • Dimensional Characteristics: HR coils are known for their wider tolerances and are often thicker compared to CR coils.
   • Formability: Hot-rolled steel tends to be more ductile and easier to form, making HR coils suitable for applications where precise dimensions are not critical.

Applications:

• CR Coils: Precision engineering applications, automotive parts, appliances, construction components requiring tight tolerances.
• HR Coils: Structural components in construction, manufacturing of welded steel tubes, general fabrication where dimensional precision is not critical.

In summary, the choice between CR and HR coils depends on the specific requirements of the intended application, considering factors such as surface finish, dimensional accuracy, strength, and formability.
