    摘要: A concrete column forming tube (10) and method of making same for receiving poured concrete therein to produce a concrete column is characterised by a smooth inside coated surface (16) in the forming tube (11) to eliminate spiral seam lines and other undesirable characteristics on the outside surface of the formed concrete column. The tube (11) is formed from spirally-wound plies (12) of paper adhered together and has a centrifugally-cast epoxy resin coating (15) sprayed onto the inside surface (13) of the spirally-wound tube (11) while the tube (11) is rotating to produce a smooth inside coated surface (13) on the forming tube (11).
