Welded Steel Knife Plate to Timber Post

There are several methods for securing a timber post to a solid poured  concrete pier, slab or foundation.  With a welded steel knife plate to timber post, a flat piece of plate steel with rebar fingers is embedded in to the concrete.  Then the elevated post base is attached to the timber post through a knife plate which is held together with a steel pin and a couple of pegs to hide everything.  After the frame is installed you simply weld the steel plate to the bottom of the knife plate post base joining everything together.

  1. After you position the post on this cement footing, can you then place stone around the footing? How would you recommend capping off the stone? Would this be done just at the start of the wood post or above it?


  2. It is best to start the stone cap as close to the bottom or right below the post to prevent the post from rotting. You can increase/decrease the depth of the spacer on the base to dial in the exact height that you need.

  3. Do you have recommended sizes for the steel plate components for a 10×10 post? Do you have any CAD details you could email?

  4. I am interested in the purchase of this product, Could you forward me information on procurement for a project I have in the works.
    Thanks for your time

  5. For anything that you install inside the wood that is made out of steel I’d highly recommend giving it several coats of “Zinc it” or something similar that gives it a zinc coating to provide it with a durable rust inhibitor.

  6. Tom, that is a great idea and one Brice also strongly recommends. Getting them hot-dipped galvanized is the way to go.
