Open-Top Ground Screw



1. Product Overview
Chudu Metal Hot-Dip Galvanized Solar PV Open-Top Ground Screw Pile is a foundation component designed for ground-mounted photovoltaic systems, solar farms, and other ground solar support structures.
The ground screw features an open-top design without a flange plate, allowing a compatible solar mounting post or steel support tube to be inserted directly into the upper opening. The inserted post can then be secured through side bolts, set screws, or other customized mechanical connections.
The lower section of the pile features a continuous helical structure that allows the ground screw to be mechanically driven into suitable soil. This provides an efficient foundation solution for solar mounting structures and can reduce the need for conventional concrete foundation construction under suitable project conditions.
Manufactured from carbon steel with a hot-dip galvanized surface, the ground screw provides structural strength and corrosion protection for long-term outdoor applications.
Ground screw diameter, length, wall thickness, top opening size, helical dimensions, and connection details can all be customized according to customer drawings and project requirements.
2. Key Features
Open-Top Design
The open upper end is designed to receive a compatible solar mounting post or steel support tube, providing a practical connection between the foundation and the upper photovoltaic support structure.
Without Flange
This model does not use a welded top flange plate and is suitable for solar mounting structures using an inserted-post connection.
Reliable Mechanical Connection
The solar mounting post can be secured inside the ground screw through side bolts, set screws, or other customized fastening methods.
Helical Ground Installation
The lower spiral structure allows the ground screw to be mechanically rotated into the soil using suitable installation equipment.
Hot-Dip Galvanized Surface
The hot-dip galvanized coating provides corrosion protection for outdoor and underground applications.
Carbon Steel Construction
The steel structure provides the mechanical strength required for photovoltaic foundation applications.
Efficient Installation
Under suitable soil conditions, ground screws can reduce excavation, concrete pouring, and curing processes compared with conventional concrete foundations.
Customized Specifications
Diameter, length, wall thickness, helical structure, connection holes, and other dimensions can be manufactured according to project requirements.
OEM & Drawing-Based Manufacturing
OEM production, drawing-based manufacturing, and sample-based customization are available.

4.Open-Top Connection Design
The upper section of the ground screw is manufactured as an open steel tube without a flange plate.
After the ground screw is installed into the soil, a compatible solar mounting post or support tube can be inserted into the top opening.
The post is then mechanically secured using side bolts, set screws, or another connection method specified by the project design.
The top opening diameter, connection hole quantity, hole diameter, and hole position can be customized according to the matching solar mounting post.
5.Helical Ground Screw Structure
The lower part of the ground screw features a continuous helical profile designed for mechanical installation into the ground.
During installation, rotational force drives the screw pile into the soil while the helical section helps the pile penetrate and engage with the surrounding ground.
The helical blade diameter, pitch, number of turns, helical section length, and pile tip structure can be adjusted according to different project specifications.
6.Installation Process
1. Foundation Layout
Determine the ground screw positions according to the solar mounting system layout and engineering design.
2. Ground Screw Installation
Use suitable ground screw installation equipment to mechanically rotate the pile into the soil.
3. Depth & Alignment Adjustment
Control installation depth, verticality, and positioning according to project requirements.
4. Solar Post Installation
Insert the compatible solar mounting post or steel support tube into the open top of the ground screw.
5. Mechanical Fastening
Secure the post using bolts, set screws, or a customized fastening structure.
6. Mounting Structure Assembly
Install the solar mounting beams, purlins, rails, braces, and photovoltaic modules according to the system design.
