The PUW post base provides a clean look while providing a 45mm stand off height above the ground. reducing the potential for decay at the post end. The PUW can be fixed to a concrete base with M10 resin anchors. All PUW bases are hot dip galvanized. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel. Galvanizing is probably the most environmentally friendly process available to prevent corrosion. Hot dip galvanizing is the process of coating iron or steel with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F). During the process, a metallurgically bonded coating is formed which protects the steel from harsh environments, whether they be external or internal.
