Steel Pile Liners
Durable, lightweight and proven culvert solutions for New Zealand & Australia

SwiftSteel™ steel Pile Liners are designed for demanding civil, rural and infrastructure projects across New Zealand and Australia. Combining high strength-to-weight performance with rapid installation and long service life, they provide a cost-effective solution for drainage, stormwater, road, and rail projects where reliability and compliance are critical.
Why Choose Steel
Pile Liners?
Pile liners can look like a relatively simple component, but their job isn't always simple. They need to retain their shape during handling and installation, resist ground and concrete pressures, prevent fall-in and seepage, and provide a reliable form for the finished pile. In demanding civil and marine environments, the physical properties of the liner can therefore matter as much as its initial cost.
The spirally wound tubes produced by our tubeformers feature a patented seam cavity, which both stabilises the tubes and locks the seams into place, ensuring that tolerances are maintained even during handling and transport, and ensuring durability on site.

SwiftSteel™ Advantages Include:
Off The Shelf
SwiftSteel® pile liners from ARLO Express Sheetmetals are available off the shelf and come in a comprehensive range of stocked and minimal lead-time bespoke sizes. These lightweight piling liners can be quickly tailored to meet a wide range of construction and engineering needs.
...or Bespoke
We keep 3 and 4-meter lengths in stock for quick delivery or pickup and also provide custom fabrication to meet unique project requirements. Our manufacturing process means we can essentially provide any length of piling, for in-ground or above-ground piles, piers or columns.
All-weather - Easy Handling
SwiftSteel® pile liners are suitable for all weathers, are very cost-efficient and perfect where unstable soil conditions are present or there are unusual engineering specifications, such as in marine environments or earthquake regions. Handling on site is easy too as they weigh just 13kg for a 300mm x 3m tube.
Durable & Tough
They offer superior crush strength, durability, weather resistance, and versatility compared to other options on the market.
On-Site Durability
The spirally wound tubes produced by our tube-formers feature a patented seam cavity, which both stabilises the tubes and locks the seams into place, ensuring that tolerances are maintained even during handling and transport, and so ensuring durability on site.
Steel vs Plastic (HDPE) Pile Liners
Whilst plastic/HDPE has its benefits, steel brings a different set of advantages — rigidity, crush resistance, dimensional stability, adaptability and installation robustness — that can make it the better engineering choice for particular piling applications.
| Consideration | Steel pile liner | Plastic/HDPE liner |
|---|---|---|
| Rigidity | High | Lower/more flexible |
| Crush/impact resistance | Strong advantage | Depends on wall thickness/design |
| Dimensional stability | Strong | More susceptible to deformation |
| Corrosion | Requires appropriate specification/protection | Excellent inherent resistance |
| Marine suitability | Good when correctly specified | Good, particularly where corrosion resistance dominates |
| On-site modification | Straightforward with standard metalworking equipment | Possible, but different joining/cutting methods |
| Bespoke diameter/length | Excellent with SwiftSteel | Manufacturer dependent |
| Concrete placement/formwork | High rigidity is advantageous | Requires appropriate design |
| Recyclability | Steel has an established recycling stream | Material/recovery dependent |
Typical Applications

Permanent Pile Liners
Simplifies construction and reduces preparation time, preventing seepage and fall-in. Resists the distortions caused by the hydrostatic pressures of concrete.

Concrete Void Formers
Lightweight and economical for use in any concrete structure including buildings and bridges. When installed in bridges and concrete structures, it will not leach from surrounding concrete.

Column Formers
Simplified column forming in buildings over traditional and more costly methods. Just cut to length, position and pour.
Express SPIRO® System Guarantee
SwiftSteel® tubes are stamped with the trademark "Express SPIRO® System", guaranteeing the high-quality performance of the SPIRO® Pile Liners.
