The SiteSee AI algorithms classify corrosion risk on a scale from 1 (low) to 4 (severe):
Level 1
Light surface rust, some gingering, scattered small corrosion spots:
Level 2
Moderate corrosion, heavy gingering, some larger rust spots, small spots of advanced corrosion, galvanising starting to peel:
Level 3
Deep corrosion, larger areas and bolts dark red, some flaking, galvanising peeling:
Level 4
Severe corrosion, erosion of metal, advanced flaking, rust has eaten through, scalloped edges and holes:
