DENSO SURFACE PREPARATION

For onshore and offshore pipelines, welded joints, fittings, and all civil and marine structures, abrasive blast cleaning is not always desirable or possible due to access or environmental restrictions. For 90 years Denso has been a world leader in providing innovative and permanent corrosion prevention solutions over hand tool cleaned steel surfaces whilst reducing applied coating costs and meeting the most stringent health & safety requirements.

Look out for the minimum surface preparation icons on our product pages.
