What is the difference between Hot Rolled and Cold Formed Sheet Piling?

The main difference lies in the process of which the piles are being produced. Hot Rolled Sheet Piling are produced directly in hot form from a beam blank into its final shape. Cold Formed Sheet Piling on the other hand uses Hot Rolled Coils to roll them under pressure into its final shape in cold (room temperature) forming state. As Hot Rolled Sheet Piling are formed under heat, complex interlock shapes are therefore possible however for Cold Formed Sheet Piling, it will just be a simple hook and grip type interlock.

Due to the investment required for Hot Rolled Sheet Piling and its associated machinery, there are few mills in the world who can produce such sections. EN Standard Piles are mostly produced in Europe while JIS standard Hot Rolled Sheet Piling are produced in Asia.

Feedstock of Cold Formed Sheet Piling are Hot Rolled Coils and they are largely available worldwide. Due to this availability, Cold Formed Sheet Piling are normally more readily available in lead time and are produced closer to your project location. Furthermore, the ability to buy different types of width and thickness of coils, gives Cold Formed Sheet Piling the added ability to customize new sections and shape which could be optimized to save on weight.
