Kalbarri Skywalk , Photo © Dermot Boyle Bocol Constructions were performed to ensure a high level of corrosion resistance was delivered , in addition to the material ’ s durability , longevity and low cost of ownership and maintenance . Electropolishing further delivered an aesthetically pleasing finish , complementing the structure ’ s design and natural environment . Representative of a great design , the individual sections of the stainless steel handrails were bolted in place to avoid onsite welding and for future ease of maintenance . If any of the handrails require maintenance or replacement , the individual sections can simply be unbolted for offsite cleaning and surface treatment and re-installed . The skywalk attraction recognises the Nanda Aboriginal people and their heritage , as the traditional owners of the land . Interpretive information on all facets of the park ’ s culture and natural history , including artwork created by several local indigenous artists adds to the Skywalk experience .

of stainless steel by chemical means . The process leaves a slight matt finish and provides a passive surface immediately upon rinsing , maximising the ongoing performance , durability , and corrosion resistance of stainless steel . Passivation - The treatment of the surface of stainless steel , often with acid solutions ( or gels ), to remove contaminants and promote the formation of the passive film on a surface that was freshly created , e . g ., through grinding , machining , or mechanical damage . Electropolishing - A factory bath method of improving corrosion resistance and brightening the surface of components . It uses electrical current rather than chemical means to selectively remove peaks and reduce surface roughness to give a deep lustre . Electropolishing also improves corrosion resistance by thickening the protective passive film which delivers durability and performance in stainless steel for extended product life .
