Oil and Wax finish. Galvanised and acid etched (100% rust proof). Handmade by Stephen McRae so dimensions, colour and shape may vary. Just like the Wrought Iron Wren the galvanised Wren has been individually heated in a gas fired forge to around 1000 degrees Celsius. Each 3mm thick steel cut out is forged and formed over the anvil using a handheld cross pein hammer. Therefore, each wren despite its uniform cut out shape is given its own individual 3-dimensional shape. It is then welded onto a 6mm diameter round steel rod 1200mm long which has previously been forged to have a hook ideal for hanging birdfeeders (coconuts, fat balls) and small lanterns from. Unlike the wrought Iron Wren it is then Galvanised in its entirety. If looked after and not bent, this Galvanised version of the wren offers maintenance-free 100% corrosion protection from rust for up to and over 20 years.
