They provide a solid and reliable foundation that can withstand any challenge, ensuring the safety and comfort of the occupants.

applications of Steel Screw Piles

Construction Foundation Engineering
In construction foundation projects, steel screw piles are widely used for high-rise buildings, bridges, and industrial facilities. Their high strength and excellent load-bearing capacity effectively enhance foundation stability and reduce settlement risks. Especially in soft soil areas, steel screw piles can quickly penetrate various soil layers through their unique rotary drilling method, providing reliable support.

Marine Engineering
In the field of marine engineering, steel screw piles are commonly used for the construction of docks, breakwaters, and offshore wind power foundations. Due to their superior corrosion resistance, they can be used for long periods in harsh marine environments. Additionally, the fast installation speed and minimal environmental impact of steel screw piles make them suitable for construction in sensitive sea areas.

Road and Railway Engineering
In road and railway projects, steel screw piles are used for subgrade reinforcement and bridge foundations. Their efficient construction speed and low disturbance to the surrounding environment allow for construction in busy traffic areas or ecologically sensitive regions. Moreover, steel screw piles can adapt to different geological conditions, ensuring the stability and safety of roads and railways.

Energy Industry
In the energy sector, steel screw piles are utilized for the foundation construction of solar power plants and wind farms. Since these projects are often located in remote areas, the rapid deployment capability and adaptability of steel screw piles make them an ideal foundation material. Furthermore, the recyclability of steel screw piles aligns with the sustainability requirements of the energy industry.

Hydraulic Engineering
In hydraulic engineering, steel screw piles are employed for the foundations of dams, levees, and pump stations. Their excellent waterproof performance and durability ensure the long-term stable operation of hydraulic facilities. Additionally, the flexibility of steel screw piles allows engineers to design appropriate foundation structures based on terrain and flow conditions.

Steel Screw Piles Buying Guide

Understanding Project Requirements
Before purchasing steel screw piles, it is essential to clarify the specific demands of the project. This involves understanding the required load-bearing capacity, geological conditions, environmental factors, and expected lifespan. For instance, in regions prone to earthquakes, selecting steel screw piles with enhanced seismic resistance may be necessary. Additionally, consider the transportation situation and equipment accessibility at the construction site to ensure smooth delivery and installation of the steel screw piles.

Selecting Appropriate Material
Steel screw piles are typically made from various grades of steel, such as Q235 and Q345. Choosing the right grade based on the project's load requirements and budget is crucial. For instance, high-strength Q345 steel might be necessary for bridge projects with substantial load-bearing demands. Moreover, considering the long-term underground usage of steel screw piles, their corrosion resistance is an important factor that cannot be overlooked.

Determining Dimensions
The diameter and length of steel screw piles should be determined according to the foundation depth and load requirements. Common diameters range from 200mm to 1200mm, with lengths reaching up to several tens of meters. When choosing, consult professional engineers or sales advisors to ensure the selected dimensions meet the project's needs. For example, a high-rise building may require larger diameter and longer steel screw piles to ensure stability.

Considering Installation Method
The installation method of steel screw piles significantly impacts their performance and cost. Traditional piling rigs may offer lower costs but could cause considerable disturbance to the surrounding environment. In contrast, static pile drivers allow for installation without disturbing the surrounding soil layers, making them suitable for projects with stringent environmental standards. Therefore, when purchasing, consider the specific circumstances of the project and budget constraints to choose the appropriate installation method.
 

frequently asked questions

1. How are steel screw piles manufactured?

Helical piles are created by welding a couple of steel thread threads on the shaft to present adequate downward pressure to the soil as it's screwed to the ground.

2. What materials are used to make steel screw piles?

Screw piles are typically manufactured from high-strength steel using varying sizes of tubular hollow sections with helical flights.

3. What is the load-bearing capacity of steel screw piles?

As a foundation to support vertical column loading, steel screw piles are typically used for working (or serviceability) loads of up to 1000kN.3

4. How deep can steel screw piles be installed?

The depth of screw piles can vary from a minimum of 8 feet to over 30 feet, depending on the project's requirements. The requirements will specify a load capacity in which the pile has to hold. The screw piles are installed until the applied torque indicates if this minimum specified pile capacity has been achieved.

5. What are the benefits of using steel screw piles over traditional foundations?

Screw pile foundations are considered environmentally friendly due to their minimal site impact during installation. They cause less soil disruption than traditional digging and excavation methods, as they are simply screwed into the ground without needing large-scale trenching or earth removal.

6. Can steel screw piles be used in areas with poor soil conditions?

Helical screw piles are commonly used in residential construction to provide a sturdy foundation for homes and small buildings. They are beneficial in poor soil conditions where traditional foundations might struggle.

7. Are steel screw piles resistant to corrosion?

All Postech Screw Piles® are hot-dip galvanized according to ASTM A123M. This metallurgical process protects the pile against corrosion, resulting in an estimated minimum useful life of 75 years.

8. How long does it take to install steel screw piles?

In many cases, screw piles can be installed in a matter of hours, significantly reducing construction time compared to other foundation methods, on average 20 minutes per pile to install.

9. What equipment is required for installing steel screw piles?

The piles are installed with a mini excavator. They are driven into the ground much like a wood screw. The screw pile rotates in the ground until it is well anchored. Our certified installers have state-of-the-art equipment to calculate the torque, or the strength achieved.

10. Can steel screw piles be reused or recycled?

A significant advantage of screw pile foundations over traditional concrete foundations is their reusability and recyclability. Screw piles are made from steel, which is a highly recyclable material. At the end of their use, screw piles can often be unscrewed and either reused at a new location or recycled.
