CORROSION CONTROL
& COATINGS


Onsite corrosion control and protective coating services to extend asset life and maintain plant performance.

PROTECTING YOUR WATER TREATMENT ASSETS


Neumann Water provides onsite corrosion control and protective coating services that extend asset life and maintain the performance of water treatment facilities. Our coating services support maintenance and upgrade projects, addressing corrosion issues before they become critical failures and protecting newly installed or refurbished equipment.

For major coating works requiring specialist facilities, we leverage the comprehensive capabilities of Neumann Industrial Coatings. This includes hot-dip galvanising, abrasive blasting, powder coating and advanced industrial painting systems. This integrated approach provides complete corrosion protection solutions from field repairs through to factory-applied coating systems.

All coating work is performed to manufacturer specifications, Australian standards or client requirements, with appropriate surface preparation and quality control. We understand the demanding environments that water treatment equipment faces and select coating systems that provide long-term protection and performance.

ONSITE CORROSION CONTROL CAPABILITIES




SURFACE PREPARATION & COATING APPLICATION


We provide onsite surface preparation and coating application for equipment that cannot be removed for workshop treatment. This includes hand tool and power tool cleaning, spot repairs and touch-up coating, protective coating application to client specifications, and maintenance coating programs for structures and equipment. Our team uses appropriate surface preparation methods and coating systems matched to the service environment and expected performance.
