Building a Metal Insert for System Retaining Wall

[WallEGuy]

Hello,

First post here. I am trying to build an insert for concrete system retaining wall systems that is made from metal. I am essentially trying to develop a sleeve that has the least thickness possible while still maintaining ASTM standards of 2,500 PSI, and < 10% absorption. The dimensions would match that of your standard block, 10" deep, 10" wide, and 6" tall.

Can anyone suggest a type of metal which can bear this much pressure and be resistant to oxidation?

Thank you!

Look at pile steel pipe materials. There are different grades. I would also evaluate coatings for corrosion protection. Work with a structural engineer for design.
