Steel structure warehouses are constantly exposed to outdoor elements such as wind and rain, making them prone to rust over time. Today, steel structure experts will introduce several rust removal and prevention methods for steel warehouses to enhance understanding and guide effective treatment when corrosion occurs.

1. Sandblasting Rust Removal:
   This manual rust removal method uses compressed air to propel abrasives (typically quartz sand) onto steel surfaces. While effective, it has limitations such as a limited coverage area, lower surface roughness, and challenges in meeting friction coefficient requirements.

2. Non-Metallic Protective Coating:
   Spraying non-metal protective layers (e.g., specialized paints or coatings) onto the steel surface isolates it from environmental factors, achieving rust prevention. This method is cost-effective and easy to apply but requires reapplication every few years.

3. Acid Pickling Rust Removal:
   Acid solutions are used to dissolve rust and contaminants on the steel surface. After treatment, thorough rinsing with water is essential, followed by passivation to prevent future rust formation.

   
   

Steel structure warehouses typically employ the above methods for rust removal or prevention. Specific solutions and operational plans should be tailored to the actual conditions of the structure.
