A Zinc Plating Scaffolding Bottom Cup is a type of scaffold fitting used to secure the scaffold structure to the ground or other surfaces. The bottom cup has a cylindrical shape with a flat base and is designed to fit over the end of a vertical scaffold tube. It is typically used in conjunction with a base plate and a jack to provide a stable and level foundation for the scaffold structure. The zinc plating of the Zinc Plating Scaffolding Bottom Cup helps to protect it from rust and corrosion.
