Steel Coils

OfBusiness’ steel coil range helps you select products that suit your requirement. The steel coils sold on OfBusiness.com have excellent strength, ductility, weldability, and bendability. You can find Hot Rolled coils between 2 ­- 7 mm thick and Cold Rolled coils between 0.15 ­- 3 mm. Read more about the differences, applications and features of CR and HR coils.
HR Coils
Hot rolled coils are more malleable and perfect for industrial applications. Generally, hot rolled has a blue­ grey appearance and a rough feel once it completes the rolling process. Hot rolled coil is broadly known for its exceptional quality and consistency.
Features of HR Coils
● High tensile strength
● Abrasion resistance
● Durability
● Excellent finish
● Lower cost as it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required.
Where Should You Use HR Coils?
● Pipes
● Tanks
● Railway cars
● Bicycle frames
● Ships
● Engineering and military equipment
● Automobile and truck wheels frames and body parts
● Feedstock for cold rolling mills
● Feedstock for higher value­added steel products
● Process industry
● Marine environments
● High­end construction
CR Coils
Cold rolled coil has higher strength and hardness, but it’s not that ductile. It is suitable for outer parts of automobiles which require anti­dent properties. Unlike HR coils, CR coil is rolled to its final dimensions below scaling temperatures.
Features of CR Coils
● Greater degree of ductility
● High tensile strength
● Excellent dent resistance quality
● Good magnetic properties
● Welding properties
Where Should You Use CR Coils?
● Precision tubes
● Steel containers
● Bicycle frames
● Furniture
● Automobile and truck wheels frames and body parts
