How to avoid such localized corrosion damage

This type of corrosion-induced fracture at the root of the steel pipe is mainly caused by the prolonged contact of the bottom part with moist ground, along with the accumulation of rainwater and dew. The solution is quite simple: 1. **Prevent direct contact with the ground at the bottom**: When installing, keep the bottom of the steel pipe a few centimeters above the ground, or use a concrete block to raise it, so as to avoid water accumulation. 2. **Proper anti-corrosion treatment**: The surface of the steel pipe can first be coated with rust-proof paint, followed by a layer of topcoat with good weather resistance (such as epoxy resin paint), with special attention paid to the area near the ground. 3. **Regular inspection and maintenance**: Check the bottom of the railing every one or two years; if the paint has worn off, repaint it to prevent rust from spreading. 4. **Improve drainage**: The surrounding ground can be made sloped to allow rainwater to flow away quickly, preventing it from accumulating at the base of the steel pipes. By paying attention regularly and performing some minor maintenance, the lifespan of the railings can be significantly extended. .
