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.
