Systems Scaffolding is a fast-erecting modular scaffolding system made of galvanized steel. It provides an opportunity to achieve high-productivity on irregular structures and restricted entry situations. Posts and horizontals make up the two principle components and their connecting hardware is permanently set in place. Each post is fitted with 360° ring sets spaced 21″ apart. Systems can utilize OSHA grade wood plank and/or its own steel hook on plank that comes in lengths from three feet to 10 feet.
