I just built a 54 foot by 6.6 foot covered porch on the front of my house. I am not sure what the best naterial is to use on the floor. I have looked at EOn, Tendura, Trex, Magongony.I would appreciate some feed back on this subject. Jeff

Tongue-and-groove redwood, mahogany, teak or Ipe come to mind. I don't think the synthetic decking comes in tongue and groove.

If you want to save the rain forest and avert global warming, avoid tropcial woods like Ipe, Mahogany, Teak etc...

Domestically grown cyprus, redwood, cedar, douglas fir and even treated yellow pine would work and be more economically friendly and be from a more renewable resource than tropical hardwoods.
