Abstract
Fifteen different types of commercial precoated sheet steels have been investigated from the corrosion viewpoint. Of the coatings four are hot-dipped, seven are electrolytic and four with an organic composite coating. The sheet materials are commercially available and intended primarily for the automotive industry. The sheet materials have been examined both with an electro-coat primer and with a full-paint system. The test plates have been exposed during two years in industrial and marine atmospheres, in outdoor scab-testing and in mobile exposure. The corrosion attack has been evaluated by assessment of spread of defects from scribes, blistering and propagation of rust from stone chipped areas.
