Zinc top, patinated and polished.  Many colours and effects can be achieved on zinc sheet, from almost black to reds, purples and bluey greys. With aluminium, the tops are corroded and then polished back to a shine, leaving hundreds of tiny dark pits and spots, and can be made to look genuinely old.   Waxing them with a good product means these tables can be left outside, and will only improve in appearance with time.

A simply constructed small wine or cafe table, with a choice of top material.  Aluminium or Zinc, patinated and polished, or painted same as table frame.  Inexpensive, stylish and durable.
