Product advantage
One of the main advantages of using large diameter piling pipes is their ability to withstand heavy loads. These pipes are designed to withstand tremendous pressure, making them ideal for deep foundation applications in large construction projects. Their large diameter also increases soil displacement, thereby enhancing stability and reducing settlement issues. In addition, the spiral welding process used in the manufacture of these pipes ensures a strong and durable bond, minimizing the risk of structural failure.
Product Shortcoming
The cost of producing high-quality large-diameter piling pipe can be higher than traditional options, which can affect project budgets.
In addition, the installation process can be more complex and time-consuming, requiring specialized equipment and a skilled workforce. If not managed properly, this can cause delays to project timelines.
