Stainless steel is one of the most durable options for an internal or external handrail or balustrade system. However, to help maintain its appearance we do recommend that it will require some maintenance so as to keeps its initial appearance. Depend upon the location and application will determine what maintenance is requiring. For example, systems installed in areas with high levels of contamination (such as city centers or near the sea) or near water (swimming pools or boats) may require more frequent cleaning than those in a rural area. In all cases a chemical cleaner will remove any contamination that poses any potential affects to the durability of the steel.
