Product Types and Description: Galvanized Steel Ground Screw Varieties
Galvanized Steel Ground Screw and ground anchor screw come in multiple types, each tailored to specific project needs. Below are the most common varieties, their features, and ideal applications:
1. Helical Galvanized Steel Ground Screw
This is the most widely used type ofGalvanized Steel Ground Screw, featuring a helical blade welded to a steel shaft. The blade design ensures the ground anchor screw penetrates the soil smoothly and creates a tight bond, distributing load evenly. It is ideal for light to heavy-duty applications, including solar panel mounts, outdoor structures, and temporary construction sites. The hot-dip galvanized coating enhances its durability in outdoor and humid environments.
2. Threaded Ground Anchor Screw
The threaded ground anchor screw is a specialized Galvanized Steel Ground Screw with a full-length thread, designed for quick installation and precise positioning. It is often used in projects requiring adjustable height or easy removal, such as temporary fences, event stages, and garden structures. The galvanized steel construction ensures it resists corrosion even when exposed to frequent handling and outdoor elements.
3. Flanged Galvanized Steel Ground Screw
Equipped with a welded flange at the top, thisGalvanized Steel Ground Screw simplifies attachment to upper structures like steel frames, concrete slabs, and wooden beams. The flange provides a large contact area for secure bolting, making it a preferred ground anchor screw for permanent buildings, carports, and industrial warehouses. Its direct sales availability makes it a cost-effective choice for large-scale projects.
4. Double-Helix Ground Anchor Screw
For projects in soft soil or areas requiring maximum stability, the double-helix Galvanized Steel Ground Screw is unmatched. With two helical blades of different diameters, thisground anchor screw increases soil engagement and load-bearing capacity significantly. It is commonly used in wind turbine foundations, retaining walls, and coastal construction, where corrosion resistance and structural strength are critical.

Customer Design
Our engineers design efficient ground screw anchors to have certain attachments or have specialized ends to penetrate hard surfaces for your outdoor space.
Ground Screw is widely used in medium to large-scale solar farm installation. Material of ground screw is Q235B steel. The hot-dip galvanized treatment over ground screw surface ensures the ground screw to be anti-corrosive.
