Plated steel hardware is designed for use in arid environments where corrosion is not a major factor or as Individual Protection Equipments (rather than C.P.E.) such as, indoor climbing gyms or artificial walls, and routes that are unlikely to be repeated (short sighted in today's growing sport).  Plated bolts should be equipped with Plated anchor systems so that any oxidization will to be equally apparent on both bolts and hangers.  Plated steel anchors need to be inspected regularly in order to asses the integrity of the placement.  Plated Steel Anchors will eventually need to be replaced. 

Always Inspect Anchors!

Important Safety Note:  The use of top anchors for top roping should be questioned. At many sportclimbing areas the top anchors are used repeatedly for toproping. Visible wear can be seen and climbers still top rope directly from the top anchors. This is a Lazy Practice that should be stopped! It takes only moments for the leader to set up the top rope using quickdraws. This saves the anchors, saves time and money and it could even save someone's life! As the last climber, take the time to rappel verses being lowered down, rappelling will help save the anchors.Please help by setting an example.
