Very endurable table made from steel. 
Diameter 120 cm, height 75 cm.
Table top thickness 6 mm.
We treat the surface occationally with a lineseedwax (a mix of lineseed oil and bees wax) to keep it smooth and soft. The table is made from corrosion resistant steel. Should it get a stain from food or drinks, it may corrode, but if you wipe of the table it goes away.
If you use the table outside - which is absolutely possible - it will get a corroded red/brownish surface. But when it has got that surface it creates a barrier that prevents it from further corrosion. It's not corroding to little pieces.
