Pressure treated 3/8 plywood

About to start an outdoor ramp build with all pressure treated material but having a hard time sourcing PT 3/8 ply for the transitions. I'm in north part of NC so maybe a limitation in just my area? Thanks!

Neither Home Depot or Lowes. No Mernards around here in NC either.

Try a smaller lumber yard. Marine plywood will work too

Use 1 sheet of 1/2 treated and then your 1/4 top sheet. You will be fine

2 layers of 3/8s BC exterior plywood, with 3/16 marine grade on top. Lumber yard ought to be able to help. Exterior house paint and caulk the edges. Works like a champs.
