A steel pile is a long, slender column made of steel that is driven deep into the ground to support structures like buildings and bridges. These piles are used to transfer the load of a structure to deeper, more stable soil or rock layers, ensuring stability and preventing settlement. Steel piles are often chosen for their strength and durability, making them suitable for various soil conditions. They can be installed using different methods, such as driving or drilling, and are commonly used in construction projects where traditional foundations may not be effective, especially in areas with weak or unstable soil.
