Why HDPE
The data behind our material choice. Lighter, lifelong and lower-maintenance — by design, not marketing.
HDPE is immune to rust. There's no coating to fail. Over the life of a mine install, eliminating paint prep and periodic repaint cycles removes a significant recurring cost — and the downtime that comes with it.
Steel marine structures typically go into dry-dock every 2–3 years for inspection and recoating. HDPE can be visually checked on site, which changes the operating economics.
HDPE absorbs impact rather than denting permanently. That matters when barges, cranes and pump bodies come into regular contact with the structure.
Across the life of the asset, lifecycle cost for HDPE is typically lower than steel when maintenance and downtime are included — not just first-install capital.
HDPE resin is ≈ 3.1 kg CO₂e/kg. But because an HDPE float needs roughly 8× less mass than steel for equal buoyancy, net cradle-to-gate footprint drops roughly 55–80% — indicative, not a marketing claim.
