In light of the Q&A response that the tote chute is smooth and the platform is "orange-peel" where does one get orange-peel surface HDPE?

We bought 3 sheets of 1/4" x 4' x 8' HDPE from Alro Plastics. My company gets a bit of a discount and they added another discount because we are a FIRST Team so I got them for $50 a sheet!

Much cheaper than McMaster-Carr and we were able to go pick it up. Check your local plastic supplier.

Does anyone know what finish is on these sheets from McMaster? Or if these sheets are stress relieved? I haven't managed to find that information on their site.

Also, I see marine-grade HDPE on McMaster as well (9785T561). Are there any significant performance or friction differences between them? They are almost twice the price.

Thanks!
