Relevant Fields of Application

Potable Water
Potable systems must protect water quality from source to tap. Materials need to be lead free, non-leaching, corrosion-resistant and built to meet recognised standards. Long-term reliability isn’t optional, it’s expected.
Rainwater Harvesting
Rainwater systems manage variable water quality and environmental exposure. Long-term durability and reliable jointing underpin effective reuse.
Non Potable & Process Water
Non-potable and process water systems still demand durability and fit-for-purpose design. Variable water quality and reuse applications require corrosion-resistant, reliable, cost-effective materials.
Industrial Piping
Industrial systems operate under pressure, temperature fluctuation and continuous load. Performance depends on corrosion resistance, material compatibility and compliance with recognised standards.
