Solar Anchor Ground Screw – The Reliable Foundation for Solar Power Plants

Solar Anchor Ground Screw – The Reliable Foundation for Solar Power Plants

Q235B / Q355 • HDG 80μm • Diameters 48–114mm • Lengths 1.6–3.5m • Customization Available

Key Features

• Foundation for Solar Plants

The primary foundation for photovoltaic ground mounting systems – fast, reliable, and cost-effective.

• Easy Installation

Driven into soil using a drilling machine. In hard rocky soil, pre-drill and pour concrete for secure fixing.

• Multiple Lengths

Fixed standard 1.6m small leaf; custom lengths 2m, 2.5m, 3m, 3.5m based on soil N-value and wind requirements.

• Multiple Diameters

Standard 76mm; also available 48mm, 60mm, 89mm, 114mm.

• Material Options

Q235B standard, Q355 on request.

• Surface Protection

Hot-dip galvanized (HDG) 80μm standard, 100μm on request – 25+ year service life.

• Customization

Flange size (180mm, 200mm, 220mm), head shape, leaf type, length – all customizable to your project.

• Types Available

With plate or without; small leaf or large leaf (for soft soils like sand, beach, landfill); adjustable for uneven terrain; U-shape head as requested.

Types by flange

Flange Top (with plate): Most common, widely used – features a pre-drilled flange for bolted connections

Tube Top (without plate): Symmetrically welded with 3 or 6 M12 bolts (M16 on request) at the top

Standard Flange Sizes (76mm Diameter)-180mm – 8mm thickness/ 200mm – 8mm thickness (most common, 8 radiating elongated holes – default option)/ 220mm – 10mm thickness

Types by Leaf / Helix

Small Leaf: 10mm width, 2mm thickness – market standard, most common

Large Leaf: Outer diameter 176mm, 200mm, 250mm – for soft soils like sand, beach, landfill, agricultural areas

• Direct Manufacturer

Factory-direct pricing, full quality control, and fast delivery.

• Quality Assurance – Direct from HQ Mount

Raw Material Inspection: Certified Q235B / Q355 with mill test reports

Welding Quality: Helix blades welded with precision for consistent performance

HDG Coating Verification: Thickness testing (80μm average, minimum points checked with 3-point average)

Dimensional Inspection: Diameter, length, flange size, helix diameter all verified

• Soil Suitability

Suitable soils: Clay soil, sandy soil

• Not suitable:

Permafrost / frozen soil: Cannot be used during freeze periods – seasonal construction required

Very low N-value soil: N=1 soils can still use ground screws, but the required quantity increases dramatically, making the cost prohibitive

Large rock / boulder areas: Not recommended. For areas with small rocks, alloy drill bits can be welded to the screw head

• Pull-Out Capacity

Pull-out capacity is evaluated on two levels:

1. Screw itself: The tensile strength of the screw – design values available upon request

2. Screw + soil interaction:

Small projects: Based on experience values

Medium projects: Calculated based on client-provided N-values

Large projects: Calculated selection + on-site pull-out testing required
