Importance of Corrosion and Fire Protection
Corrosion and fire protection are crucial for the safety and longevity of steel components. Proper maintenance not only prevents corrosion but also ensures cost savings in the long term. To address these needs, we offer comprehensive corrosion protection services from the early stages of construction.
Our Corrosion Protection Services
Blast Cleaning (Sa2 to Sa3)
- Sa2: Thoroughly removes oil, grease, dust, scale, rust, paint, and foreign contaminants, achieving an 80% removal rate of corrosion products.
- Sa2½: More intensive cleaning, removing 95% of corrosion products, with minimal residual contamination.
- Sa3: Achieves 100% removal of all contaminants, leaving a uniform metallic surface.
- Spray Painting with Hydrodynamic Units
Uses compressed air to apply paint uniformly, ensuring perfect coverage without streaks or runs. This method is fast, economical, and efficient, ideal for large areas.
Corrosivity Protection (C1-C5)
- C1 (Very Low): For interiors of heated buildings with a clean atmosphere (e.g., residential buildings, hotels, offices).
- C2 (Low): For unheated buildings and low-pollution areas (e.g., warehouses, countryside).
- C3 (Medium): For high humidity rooms with moderate pollution, urban and industrial atmospheres, and coastal areas.
- C4 (High): For chemical and industrial plants.
- C5-I (Very High Industrial): For industrial buildings with continuous condensation and high pollution.
- C5-M (Very High Marine): For buildings in highly corrosive coastal areas.
Fire Protection for Steel Structures
Steel structures can lose their load-bearing capacity quickly during a fire. The critical temperature at which steel loses half its strength can be reached within 10 minutes of a fire outbreak. To delay this process, we implement effective thermal protection, preventing the premature occurrence of the "limit temperature in steel."
