The most popular paint finish is flat black, but red oxide, grey primer, or unpainted finish are also available. All structural materials and fasteners are corrosion resistant, so the bare metal is always satisfactory outdoors. Unpainted bridges are cleaned before delivery, but customers who paint their bridges should ensure that the surface is clean and dry before painting - wash them in a strong detergent followed by thorough rinsing and drying. Use a primer formulated for aluminium alloy surfaces and allow ample drying time in a warm, dry environment before top coating.
