Plusfab -Â Ground Screw
Screw Piles, Ground Screws, and Helical Piles are all types of helical foundation systems that use spiral blades or threaded structures to anchor securely into the ground.
Screw Piles are structural helical piles commonly used for building foundations and load-bearing support systems.
Ground Screws usually feature threaded sleeve-style structures designed for fast installation in light construction and landscaping projects.
Helical Piles generally use welded helical plates to achieve higher load capacity and stronger uplift resistance.
Although their structures differ slightly, all three systems serve the same purpose:
- Fast foundation installation
- No concrete required
- Immediate structural support
- Reduced site disturbance
- Reusable and removable foundation solutions

A complete screw foundation system may include:
- Steel pile shaft
- Helical blade(s)
- Threaded section
- Top connection bracket
- Flange plate
- Pipe adapter
- Beam support connector
- Extension sections
Different top structures allow fast installation for wood beams, steel pipes, columns, and outdoor frameworks.
- Screw Piles
Heavy-duty helical foundation systems suitable for structural support applications.
- Ground Screws
Threaded screw foundations designed for fast and efficient installation in lighter structures.
- Helical Piles
Multi-helix structural piles used for higher load capacity and stronger uplift resistance.
- Spiral Piles
Continuous spiral structures offering stable soil penetration and reliable anchoring.
- Screw-In Piles
Flexible removable foundation systems for temporary or modular structures.
- Adapter Screws
Foundation systems with customized connection heads for specialized installations.
- Beam Screws
Designed for securing wood beams and steel beams in decks, pergolas, and outdoor platforms.
- Pipe Screws & Post Screws
Used for pipe columns, fence posts, lighting poles, and structural supports.
- Fast Installation
No excavation or concrete curing is required. Screw foundations can be installed directly into the ground.
- Immediate Load Bearing
Structures can often be installed immediately after pile installation.
- Strong Load Capacity
Helical structures provide excellent vertical load support and uplift resistance.
- Low Ground Disturbance
Installation creates minimal soil displacement and avoids large excavation work.
- Suitable for Various Soil Conditions
Can be used in soft soil, loose ground, and areas with shallow rock coverage.
- Flexible Structural Connections
Different head configurations allow easy connection to wood beams, pipes, columns, and steel structures.
- Reusable Foundation Solution
Most screw-in piles can be removed and reused in temporary projects.
- Reduced Construction Time
Fast installation significantly shortens overall project schedules.
The manufacturing process focuses on structural strength, welding quality, and corrosion protection.
- Main Manufacturing Steps
- Steel Tube Cutting
- Helical Plate Forming
- Position Welding
- Straightening & Alignment
- Shot Blasting
- Hot-Dip Galvanizing or Powder Coating
- Final Inspection
For Ground Screws, automatic thread-forming machines ensure consistent installation torque and stable threading quality.
Adapter Screws, Beam Screws, and Post Screws require additional precision machining for top connection structures.
- Hot-Dip Galvanizing
The most common surface treatment for outdoor corrosion resistance and long service life.
- Powder Coating
Provides additional appearance options and protective surface finishing.
- Custom Anti-Corrosion Systems
Available for marine environments or aggressive outdoor conditions.
These screw foundation systems are widely used in outdoor construction and light structural projects.
Common Applications Include
- Solar Mounting Systems
- Wooden Houses
- Deck Foundations
- Outdoor Platforms
- Pergolas & Gazebos
- Fence Systems
- Guardrails
- Sunrooms
- Temporary Exhibition Booths
- Small Warehouses
- Walkways
- Light Steel Structures
- Lighting Pole Foundations
- Signage Columns
- Pipe Support Systems
- Modular Buildings
Ground Screws are especially popular in landscaping and wooden structure projects, while Helical Piles are more suitable for higher-load structural applications.
Strict inspection procedures are applied throughout production.
Inspection Procedures Include
- Raw Material Inspection
- Chemical Composition Testing
- Yield Strength Testing
- Weld Integrity Inspection
- Dimensional Accuracy Inspection
- Helix Angle Inspection
- Shaft Straightness Inspection
- Galvanizing Thickness Testing
- Load Capacity Testing
- Thread Integrity Inspection
Connection components such as Adapter Screws and Beam Screws also undergo fitting and load verification tests.
