Introduction

INTRODUCTION TO A109 COLD ROLLED STRIP STEEL

Cold rolled steel is a low-carbon steel that is finished at room temperature. Due to its processing, cold rolled steel sheets are typically more durable than hot rolled steel, and have a better-looking finish which makes it a prime metal for applications such as automotive and appliances, where finish matters in both form and function.

Additional variables apply depending on material thickness, width, and additional processing.

Production Process

740x455_0005_Cold-Rolled
1

Steel is hot rolled to reach ideal malleability in order to increase its functionality & intended use

2

Steel is pickled to remove surface impurities—like rust & scale to restore ideal corrosion-resistant properties

3

Steel is cold rolled & finished at room temperature for optimal finish and durability

Pros/Cons

Pros:

  • Available in tight tolerances
  • Lightweight
  • Provides surface uniformity
  • Works well for products that will be chrome- or nickel-plated
  • Typically more durable than hot rolled steel
  • Has one of the best looking finishes
