1. Treatment of water ingress into the whole piece: If the angle steel is waterlogged, it should be disassembled immediately and placed in a ventilated place to dry. If the rain exposure is short (within 1-2 days), closely monitor the surface for white rust and address it promptly.
2. Treatment of minor white rust: If minor white rust or spots appear on the surface, disassemble and let it dry until the white rust turns into powder, then wipe it off and cover it with hot-dip galvanized manual spray paint to avoid secondary moisture.
3. Treatment of severe white rust
If the white rust is severe, the white rust attached to the surface must be completely removed, and the surface should be re-sprayed with hot-dip galvanized spray paint to cover it. After drying, avoid getting it damp again.
4. Optimize the storage environment. During the rainy season, keep the storage environment ventilated and dry, and avoid direct contact with damp ground or soil. When storing outdoors, it is recommended to cover it with a rainproof cloth.
