The main differences between hot-rolled and cold-rolled steel sheet piles lie in their manufacturing process, structural strength, interlock quality, and cost. Here’s a detailed comparison.

1. Manufacturing Process
Hot Rolled Steel Sheet Piles
Manufactured by heating steel billets and rolling them into shape at high temperatures (above 1,000°C).
The interlocks are formed during the rolling process, resulting in a more precise and durable connection.
Cold Rolled Steel Sheet Piles
Produced by bending or pressing steel plates at room temperature into the desired shape.
The interlocks are created after rolling, making them slightly less robust compared to hot-rolled piles.
2. Structural Strength & Performance
Hot Rolled Steel Sheet Piles
Have better structural integrity and higher bending strength due to the continuous grain structure.
Suitable for heavy-duty applications, deep foundations, and marine environments.
Cold Rolled Steel Sheet Piles
Slightly lower strength due to the bending process, but still sufficient for many applications.
Best suited for temporary structures, cutoff walls, and light to medium retaining walls.
3. Interlock Quality
Hot Rolled Steel Sheet Piles
Tighter and more durable interlocks, providing better water-tightness.
Ideal for projects requiring seepage control.
Cold Rolled Steel Sheet Piles
Looser interlocks, which may require additional sealing (e.g., welding, sealants) for water resistance.
4. Availability & Cost
Hot Rolled Steel Sheet Piles
More expensive due to the high-temperature rolling process.
Available in standardized profiles based on JIS, ASTM, or EN standards.
Cold Rolled Steel Sheet Piles
Generally cheaper due to a simpler manufacturing process.
Offers more profile flexibility, allowing customization based on project needs.
