When it comes to extreme environments, few places on Earth are more demanding than Antarctica. With sub-zero temperatures, severe wind exposure and corrosive coastal conditions, the Scott Base water tank replacement project was a true test of engineering resilience. And Moddex passed — with flying colours.

Selected for their lightweight design, corrosion resistance and fast installation, Moddex’s modular aluminium handrails and accessways were used atop four 40,000-litre emergency water tanks. With zero tolerance for error and no ability to “cut on site,” Moddex's pre-engineered systems arrived fully configured and ready to install, streamlining works in a tight seasonal window.

But the benefits extend far beyond the ice.

For architects and designers working in New Zealand’s high wind, coastal and corrosion zones, Moddex barrier systems offer peace of mind. Their products are rigorously tested and meet key NZBC durability and safety requirements including Clause B2 (Durability) and F4 (Safety from Falling). Whether it's aluminium for coastal zones or hot-dip galvanised steel for high-impact public infrastructure, Moddex can specify to suit your project environment.

Benefits for NZ projects:

• No on-site welding or hot works
• Engineered for compliance from the start
• Materials and finishes suited to high-wind and coastal zones
• Proven performance in environments more extreme than any in New Zealand

Whether you’re building at the beach or above the bushline, Moddex makes it easy to specify systems that last.
