Corten steel Organic coatings

Non-porous materials are much better. Glass, stainless steel, glazed bricks and tiles, washable organic coatings and paints, aluminium (anodised or non-anodised), polycarbonates and neoprene remain unaffected or can be cleaned if necessary.

The rules that apply regarding the electrochemical series of metals should be observed. If dissimilar metals are to be placed in proximity to weathering steel, then good detailing practice should ensure the elimination of traps for water and / or the separation of the metal, with an inert material.

This will apply in some cases with fixing techniques. It is common to specify weathering steel nuts and bolts in conjunction with the main structure. It is also possible to use stainless steel or even galvanised steel fixings, providing the latter are isolated from the surface of the weathering steel. Welding poses no problem. Most manufacturers of welding materials provide consumables suitable for the fabrication of weather-resisting steel (see page 4).
