Solar Mounting Systems
Screw piles can be a candidate foundation for ground-mounted photovoltaic arrays where loads, soil conditions, access, corrosion exposure, installation controls and testing are suitable.
Screw Piles
Steel screw foundations for suitable ground conditions, with pile geometry, material, corrosion protection, installation criteria and testing confirmed from project loads and site data.

What They Are
A faster, cleaner alternative to concrete foundations.
Screw piles can provide a practical ground-anchoring route for solar, light construction, fencing, signage and temporary structures when the loads, soil, access, corrosion exposure and installation controls are suitable.
For suitable ground and access conditions, screw piles can reduce excavation, spoil and concrete curing activities. Capacity, corrosion protection and acceptance criteria still require project-specific verification.

Technical data framework
Project-specificGround Screw Pile Technical Data Template
Use this template to define a project-specific pile schedule. Dimensions shown in a catalog are indicative until the reactions, ground, durability and connection requirements have been reviewed.
Required design inputs
- Compression, uplift, shear and moment reactions
- Geotechnical profile, groundwater, frost and obstructions
- Pile-head interface, tolerances and supported-system geometry
- Design life, soil/atmospheric corrosivity and inspection access
- Installation equipment, test locations and acceptance plan
Decision boundaries
- Not selected from soil description alone
- Installation torque is a control only where a project-specific relationship is approved
- Capacity requires design and the agreed verification method
- Coating and sacrificial thickness follow the exposure and design-life assessment
| Parameter | Published value status |
|---|---|
| Shaft type and diameter | By approved pile schedule |
| Wall / bar thickness | By structural and durability design |
| Length and extensions | By ground profile and installation criteria |
| Helix geometry | By load-transfer design |
| Material grade | By drawing and material specification |
| Head / coupling detail | By supported-system interface |
| Corrosion protection | By exposure and design life |
| Installation / test criteria | By approved method statement and test plan |

Request project data sheetWhy Screw Piles
Engineered advantages over poured concrete.
Construction Sequence
Follow-on work can begin after installation acceptance without concrete curing
Corrosion Route
Material, sacrificial thickness and coating selected for the site exposure and design life
Capacity Verification
Compression, uplift and lateral criteria confirmed by design and the agreed test plan
Site Disturbance
Excavation and spoil can be reduced where ground conditions permit direct installation

04BAOYU Ground Screw Pile 1
Foundation options that may support later removal where the design and ground conditions permit.
View Details
05BAOYU Ground Screw Pile 2
Low-disturbance pile foundations for decks, walkways and sensitive terrain.

06BAOYU Ground Screw Pile 3
Fast steel screw foundations for cabins, modular units and small structures.
View DetailsApplications
Where screw piles are used.
Lightweight Structures
For decks, gazebos, cabins, fences and other light structures, pile geometry and acceptance criteria must be verified from the actual reactions and site information.
Temporary & Modular Structures
Temporary and modular projects may benefit from a reduced-wet-trade foundation route. Later removal or reuse depends on the design, site conditions, installation records and component condition.
How It Works
Four Steps to Quality Foundation
01
Requirements & Technical Inputs
We review loads, site data, installation method, standards, corrosion exposure and acceptance criteria, then identify assumptions and missing information.
02
Proposed Production Route
The quotation and drawings define pile geometry, material, fabrication, coating, tolerances and the applicable inspection plan.
03
Inspection, Packing & Logistics
Inspection and release follow the agreed ITP and order scope; packing and export documents are coordinated for the destination and shipment route.
04
Installation Information & Support
Installation remains the responsibility of the appointed site contractor. Available manuals and remote technical support are provided within the agreed supply scope.
