Rust on the Roof of Container Panel Houses

Rust on the roof of container panel houses can be addressed through methods such as rust removal by grinding, application of anti-rust coatings, replacement of roofing materials, or the use of waterproofing systems.

Rust Removal by Grinding and Cleaning

For rusty roofs of container panel houses, first use professional tools to grind the rusted areas, thoroughly removing the rust and restoring the metal surface to a smooth state. After grinding, clean off any oil and dust from the surface to ensure it is clean and dry, providing a good foundation for subsequent anti-rust treatments.

Application of Anti-Rust Coatings

• Lobar Cold Galvanizing Coating: This coating offers anti-rust performance comparable to hot-dip galvanizing, with a relatively simple application process that does not require the cumbersome steps of primer, intermediate coat, and topcoat. Simply apply the Lobar Cold Galvanizing Coating directly onto the properly prepared steel structure surface. After the coating dries, perform a film thickness test to ensure uniformity and compliance with standard requirements. Once applied, it forms a dense zinc powder protective film on the steel structure surface, significantly enhancing corrosion resistance. It is expected to require no refinishing for up to 10 years, greatly reducing long-term maintenance costs and frequency.
• Water-Based Rust Converter Anti-Rust Paint: Applying water-based rust converter anti-rust paint to rusted areas can effectively improve construction efficiency and reduce labor and material consumption. However, since container panel houses are made of iron, their adhesion to paint is not ideal. After being washed by rain and decomposed by acid-base oxidation, rust may reappear soon, necessitating repeated maintenance.

Replacement of Roofing Materials

If a significant portion of the roof of a container panel house has developed rust spots and the condition is severe, it is advisable to directly replace the roofing materials. For example, PVC anti-corrosion tiles or synthetic resin tiles are both excellent choices. These tiles offer outstanding corrosion resistance, with a smooth, dense surface that does not absorb water, providing excellent waterproofing and moisture resistance. They will never rust and also offer better heat insulation and sound insulation compared to color-coated steel tiles.

Use of Waterproofing Systems

The SYR Metal Roof Seamless Waterproofing System is specifically designed for metal roofs. It uses high-quality polymer emulsion as the base material, paired with specialized woven polyester fabric. Through a standardized construction process of 'one fabric, three coats,' it forms a continuous and complete waterproofing and anti-corrosion system. This system can precisely adapt to different climatic conditions, effectively solving the problem of rust and leakage on roofs.
