HOW TO REMOVE RUST FROM TMT BARS

Rust causes weakening of TMT bars through two destructive impacts on their concrete bond and their actual size dimensions. Following are several effective procedures for eliminating rust from surfaces.

• Wire brushing: A stiff metal brush removes loose rust, but it’s labour-intensive and only suitable for mild rust.
• Sandblasting: Sandblasting with high-pressure particles of sand or grit is an efficient method to eliminate heavy rust from surfaces. The method works quickly and achieves complete results which makes it suitable for big projects.
• Phosphoric Acid Cleaning: Converts rust into a stable black phosphate coating, preventing further corrosion.
• Vinegar or Citric Acid Soaking: Baths of vinegar or citric acid prove an environment-friendly rust removal technique that takes bars through 24-48 hours of soaking before scrubbing.
• Electrolysis: A low-voltage electric current runs through the electrolyte solution to treat a rusted bar submerged inside it. The effective rust treatment process requires proper attention throughout its implementation.
• Rust Converters: Rust converter liquids act as chemicals that convert rust into a protective polymer layer. The treatment method works well for locations that need on-ground bar maintenance instead of mechanical cleans.
• Ultrasonic Cleaning: This uses high-frequency sound waves in a cleaning solution to remove rust. Mostly used for small, critical components rather than construction bars.
