Anyone built their own? Struggling to find frames/legs that will stand up to the elements i.e stainless, or would I need to get these custom made by a fabricator?

I’m looking to make a simple outdoor table top (I already have some stainless steel legs) and I was astonished by the lack of outdoor suitable wood options… what are you all doing for outdoor furniture?

I can get cedar for $7.70 per board foot for rough cut, but even that is like $400 of lumber just for an 8’ table top.

EDIT: For those downvoting both me and the commenters… why? What about this wood species selection post has offended you? Please just downvote me and not the kind folks responding. Thanks!

I'd like to build an outdoor table and this is the rough material list/plans I have so far.

Tabletop: 1x6 cedar with a bordered edge. I'll be using the slat design to allow water to easily pass through when it rains.

Table frame: Pressure treated 2x4's

Legs: Pressure treated 4x4's

A few questions I have:

1.) Is the 1 inch tabletop thickness going to be too thin?

2.) Is pressure treated lumber for the frame and legs not a good idea? I'm totally cheaping out because cedar is already pretty expensive. The tabletop alone will cost about $150. With PT lumber, I guess another con is that it's non very pretty and probably won't take stain very well.

Any comment on my approach before I draw up actual plans? I'm sure there are lol.
