Screw Pile / Helical Pile / Ground Screw for Foundation

Model No.: Ground Screw

Our galvanised screw piles secure your foundation with confidence, offering a high-performance ground mounting solution for a wide range of applications, designed for long-term performance in a wide range of ground mounting Applications. Manufactured from durable Q235 steel and finished with a hot-dip galvanised coating, these helical piles are built to resist corrosion and ensure structural integrity for up to 25 years.

Whether you're installing a portable cabin, setting up a deck, mounting solar panels, or building on uneven terrain, our ground screws offer a fast, clean, and reliable alternative to traditional concrete foundations. With no digging, no curing time, and no heavy excavation equipment required, you can have a stable, load-bearing foundation in place within hours rather than days — saving both time and labour costs on your project.

Why Choose Our Ground Screws?

Traditional concrete footings require excavation, formwork, and curing time that can stretch a project timeline by days or even weeks depending on weather conditions. Our screw pile system eliminates these delays entirely. The helical design allows the pile to be wound directly into the ground, creating immediate load-bearing capacity without disturbing surrounding soil or vegetation. This makes them especially valuable for sites with limited access, sloped terrain, or environmentally sensitive areas where minimal ground disturbance is a priority.

Key Features:

Material: Q235 Carbon Steel — a robust, high-tensile steel grade known for its strength and workability
Surface Finish: Hot Dipped Galvanized for superior corrosion resistance, ensuring the pile withstands moisture, soil chemicals, and weather exposure over decades of use
Wall Thickness Options: 2.75mm, 3.0mm, 3.5mm — allowing you to match pile strength to your specific load requirements
Length Options: 1200mm / 1600mm / 1800mm / Customised to suit your soil conditions and structural needs
Top Options: Flange Top or Tube Top, giving flexibility depending on the type of structure being mounted
Installation Site: Suitable for open ground applications across a variety of soil types
Standards Compliance: AS/NZS 1170, JIS C8955:2011 — meeting recognised structural and engineering standards
Warranty: 10 Years, giving you long-term peace of mind on your investment

Built for Longevity

Every ground screw is manufactured with corrosion resistance as a top priority. The hot-dip galvanised coating forms a protective zinc layer that shields the underlying steel from rust and environmental degradation, extending the usable life of the pile to up to 25 years even in challenging ground conditions. This makes our screw piles a genuinely long-term foundation solution rather than a short-term fix, particularly valuable for structures you intend to keep in place for years, such as cabins, sleepouts, or permanent decking.

Common Uses for Screw Piles

Our ground screws are versatile enough to support a wide range of residential, commercial, and agricultural applications, including:

Portable cabins & tiny homes – Strong, easy foundations that install quickly without concrete
Decks & patios – No digging or concrete needed, reducing installation time significantly
Fencing & posts – Great for uneven or sloped ground where traditional post-holes are difficult
Solar panels – A stable, level base for ground-mounted solar systems
Vineyards & farms – Reliable support for trellises, greenhouses, and other agricultural structures
Garden sheds & sleepouts – Quick setup for backyard buildings without heavy machinery
Temporary structures – Perfect for events, marquees, and stages requiring fast setup and removal
Walkways & boardwalks – Minimal ground disturbance, ideal for parks, reserves, and coastal areas

A Smart Choice for New Zealand Conditions

Given New Zealand's varied terrain — from sloped sections to soft or waterlogged ground — screw piles offer a practical, adaptable foundation solution where concrete pours aren't always feasible or cost-effective. Their ease of installation also makes them well-suited to remote or rural sites where access to concrete trucks and heavy equipment may be limited.

Whether you're a builder, contractor, or homeowner planning a DIY project, our screw piles provide a dependable, standards-compliant foundation system backed by a 10-year warranty and engineered for decades of performance.
