I don't know what plants those are, but I'm trying to design a trellis/ arbor myself. I'm thinking of using the metal t-post for the corners. Though I haven't decided on the top yet. Good luck!

We built 6'X40' enclosure for our veggies. We used steel spikes(footings) and 4X4 posts. Only problem here is, wood changes color in a year and looks bad:( If you want to see the pictures please let me know and I will email them in the weekend.

We grow everything on them (Ash gourds. bottle gourds, bitter gourds, snake gourds and Beans).

Hey Badari,

That sounds like a a big enclosure. Sure email me some pictures I updated my preferences.

Here is a look at what I have going so far. Nothing to special, but it may work.

Thank you for the reply.
@Badari
Can you email me the pics at srilathan@gmail.com.
@Tey157 Nice trellis. But looks complicated to build.
Thank you,
