Bitumen Paint on Steel – Corrosion & Waterproof Protection
Gold Bitumen’s Bitumen Paint on Steel is a highly durable, solvent-based coating designed to protect steel 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 layer for other coating systems

No. Rust should be removed before application using wire-brushing or sandblasting to ensure proper adhesion and performance.
2. How many coats are needed for optimal protection?
Typically 2-3 coats are recommended, depending on exposure and environmental conditions.
3. What is the drying time and recoat interval?
Touch dry in about 4-6 hours at 25 °C. Recoat interval is usually 8-24 hours depending on temperature.
4. Is Bitumen Paint on Steel suitable for submerged or marine environments?
Yes. With proper surface preparation and sufficient film thickness, it is suitable for marine exposure and submerged steel components.
5. What packaging sizes are available for export?
Available in 10 kg plastic pails, 20-liter metal drums, and custom packaging for large or OEM orders.
