A jig ( 10 ) is provided for holding an elongate member ( 56 ) to be surface treated. The jig ( 10 ) comprises a beam ( 12 ) and a plurality of hangers 14 spaced apart along the beam ( 12 ). The hangers ( 14 ) have supports ( 90 ) with retaining springs ( 96 ) thereon which are arranged to support and grip the elongate member ( 56 ). The beam ( 12 ) has hook-like members ( 18 ) for engagement with a lifting bar ( 30 ) of a crane ( 28 ). The crane ( 28 ) is used to transport the jig ( 10 ) to an anodising station ( 60 ) and subsequently to transport the jig ( 10 ) still with the anodised elongate member ( 56 ) thereon to a painting station. In that way, an elongate member to be surface treated can be manually placed on the respective supports ( 90 ) and held in place by the retaining springs ( 96 ) without having to use other forms of clamps.
