How to Paint Steel Structures with Long Lasting Protection
Understanding Steel Corrosion
Steel corrodes when exposed to oxygen and moisture. Industrial settings accelerate this process through chemical fumes and abrasion.
Preparing the Steel Surface
Steel should be abrasive blasted or mechanically prepared to achieve a clean, roughened profile for maximum adhesion.
Choosing a Steel Coating System
Zinc rich primers provide sacrificial protection. Epoxy intermediates offer strong chemical resistance. Polyurethane topcoats add a durable, UV stable finish.
Correct Application and Inspection
Apply each layer at the correct dry film thickness. Inspect between coats to ensure cleanliness and adhesion.
