Coatings and corrosion control engineering

GRIT has industry-leading experience in industrial coatings and corrosion protection. Our team includes senior AMPP (NACE) coating inspectors, corrosion specialists and degree-qualified engineers with extensive corrosion and coatings knowledge. Working closely with our network of trusted and highly skilled suppliers, contractors and technical experts, we deliver practical corrosion control solutions that maximise economic, operational and ESG benefits.

With a focus on fact-based risk management, we help asset owners develop practical corrosion protection solutions aligned with relevant requirements. Our capabilities include specialist corrosion protection system design and coating specification, scope preparation, contractor engagement, quality control and independent inspection.

Our recommendations are based on transparent testing, condition data and engineering analysis. By explaining the basis for our advice, we help you make fully informed corrosion protection and maintenance decisions that support asset lifecycle value.

GRIT’s coatings and corrosion control engineering services include: 

• Condition assessment, corrosion risk evaluation and modelling for tanks, concrete and steel structures, including corrosion under insulation (CUI), stress corrosion cracking, concrete deterioration and spalling, dew point corrosion and other process-related corrosion risks.
