How to fix corrosion around base plates?

Corrosion is usually caused by galvanic corrosion between dissimilar metals, combined with crevice corrosion in gaps around fasteners.

White rust is a powdery corrosion product that forms on aluminium, often near stainless steel bolts and galvanised plates.

Yes, but only if the coating is intact. Defects around edges, holes, or joints can let moisture in, allowing corrosion to start.

Use non-aggressive abrasives to remove corrosion, then wash with an alkaline cleaner and rinse with fresh water.

Apply an aluminium conversion coating or etch primer, then a high-build epoxy primer and a polyurethane topcoat for long-lasting protection.

Isolate metals with insulating washers, seal joints with polyurethane sealant, use a zinc-rich epoxy primer, and maintain regularly.

Yes. Crevices and tight gaps can trap water and salts, causing localized corrosion beneath coatings.

Absolutely. Coastal and industrial environments with salt or pollutants accelerate galvanic and crevice corrosion.

They can be used if metals are isolated with washers or gaskets. Direct contact in the presence of moisture can cause galvanic corrosion

Annual inspections are recommended, especially around base plates and fasteners, to catch early signs of corrosion and coating defects.
