Bitumen Coating for Steel Pipes and Tanks | Iran-Made Bitumen Paint
Bitumen Paint on Steel
Bitumen paint on steel is a highly durable, solvent-based coating designed to protect metal surfaces from corrosion, moisture, and harsh environmental conditions. Manufactured in Iran using premium-grade bitumen and refined solvents, this paint forms a thick, water-resistant film that adheres strongly to galvanized and raw steel. It is widely used in industrial, marine, and underground applications.
Why Use Bitumen Paint on Steel?
- Provides long-term corrosion protection
- Excellent waterproofing for exposed or buried metal
- UV resistant – suitable for outdoor steel structures
- Compatible with industrial steel, pipes, and tanks
- Cost-effective alternative to epoxy and polyurethane systems
Applications
- Steel storage tanks (internal and external)
- Underground pipelines and steel pilings
- Bridges, docks, and marine structures
- Industrial structural steel exposed to moisture
- Protective primer for other coating systems
