Surface Finishes & Coatings
-
Natural / Black As-rolled with mill scale, often requiring secondary cleaning before any further industrial processing operations.
-
Coated / Galvanized Zinc coating for corrosion resistance, providing a highly durable barrier against harsh environmental weather conditions effectively.
-
Primed / Painted Shop-applied primer or paint coating, intended to protect structural components from oxidation during storage and transportation.
-
Shot Blasted / Pickled Cleaned surface for further treatment, ensuring that all loose contaminants are removed for superior bonding performance.
-
Sand Blasting Surface preparation for painting or inspection, creating a uniform texture which maximizes adhesion for heavy duty coatings.
