Technical Chart Snap Ties summarizes the properties and specifications of steel formwork spreaders, also known as snap ties. The document details that snap ties are made of 5.8mm thick high carbon steel with polypropylene cones on each end to space formwork plates. It provides metrics such as yield strength, elastic limit, maximum tension and elongation. Snap ties are mostly used to maintain consistent spacing between formwork for walls and columns.
1. TECHNICAL CHART SNAP TIES
