Steel balustrades are a popular choice across the UK. They offer a sleek, modern look while being exceptionally strong; however, the often-damp weather makes corrosion a concern. Let’s look at how to keep your metal balustrades looking pristine for years to come.
1. Keep them clean
Regular cleaning is the simplest yet most effective way to prevent rust on metal balustrades. Every few weeks, use warm, soapy water and a soft cloth to remove salt, dirt, and pollutants.
2. Don’t use harsh cleaning products
Avoid bleach and abrasive chemicals, which can damage protective coatings and expose steel to oxidation.
3. Add protective coatings
Apply a powder-coated, galvanised, or clear protective finish to shield the surface from oxygen and moisture. This barrier extends the lifespan of your balustrade.
4. Check and maintain the steel regularly
Inspect every balustrade’s joints, welds, and fastenings every few months. If you spot scratches or small rust spots, treat them immediately to stop corrosion from spreading.
5. Improve drainage and ventilation
Good airflow helps moisture evaporate quickly, preventing trapped water from causing rust. Your balustrade’s design should also allow rainwater to run off easily, so always buy from a specialist such as https://donkeywellforge.co.uk/what-we-make/metal-handrails-balustrades/.
6. Use quality hardware
Even if your metal balustrades are made from high-grade steel, rust can start on inferior bolts, screws, or brackets. Always use stainless steel or galvanised fixings that match the corrosion resistance of the balustrade.
By following these steps, you will protect your investment and keep your steel balustrades strong and corrosion-free.
