Screw piles (also referred to as screw anchors, helical piles, or helical anchors) are a steel screw-in piling and ground anchoring system engineered for deep building foundations. Manufactured from tubular hollow sections in varying sizes, these piles provide reliable load-bearing support for structural projects.
The pile shaft transfers a structure's load into the pile. Helical steel plates are welded to the pile shaft in accordance with the intended ground conditions. Helices can be press-formed to a specified pitch or simply consist of flat plates welded at a specified pitch to the pile's shaft.
The number of helices, their diameters and position on the pile shat as well as steel plate thickness are all determined by a combination of :
Screw pile foundations are widely used across a broad range of industries, from lighthouses, rail, telecommunications, and roads to solar PV mounting and perimeter fencing, making them ideal for projects that demand fast installation or construction work in close proximity to existing structures. They offer a host of key benefits, including shorter project timelines, ease of installation and site access, a reduced carbon footprint, straightforward removal when foundations are no longer required, enhanced safety for the on-site workforce, and lower overall construction costs.
Enables fast, equipment-driven setup without concrete pouring or deep excavation, ideal for tight deadlines and restricted-access sites.
Can be efficiently extracted and reused or repurposed when decommissioned, minimizing waste and simplifying site restoration.
Eliminates concrete and excavation expenses, cuts labor hours, and lowers long-term maintenance costs compared to traditional foundations.
How are they installed?
Powerful hydraulic motors are used to apply the large torques that are required to screw a screw pile into the ground. The motors are fastened onto handling machines that range in size from ½ T Bobcats, 20T Excavators, or up to 100T mast mounted crane rigs. The combination of hydraulic motor and handling machine is determined by:

PROFENCE.ENERGY supplies the ground mount structure for the installation of bifacial module, which is fabricated from S350GD carbon steel with a Zn-AI-Mg surface treatment, providing excellent corrosion and oxidation resistance. Unlike conventional installation methods, this design positions the beams between the module panels and utilizes cross beams to connect the vertical beams for load-bearing purposes, thereby minimizing shading caused by the support structure. This configuration maximizes the exposure of the bifacial module's underside to sunlight, thereby enhancing daily power generation.
