{"product_id":"galvanised-steel-c-posts","title":"Galvanised Steel “C” Posts","description":"\u003cp\u003eHYBUILT's galvanised steel C posts are the end posts in a post and panel retaining wall. The single sided channel lets the wall finish neatly at each end, at a step, or hard against a structure, where an H post would leave an open slot.
