Marshalltown Company

Marshalltown Company is more than a manufacturer of premium quality trowels. We are committed to leading the construction tool industry and providing the best products for the contractor to complete every job with the best results possible.

Each Permashape® blade is given a broken-in shape, precisely curved for a finisher to use directly out of the box. That shape is guaranteed for the life of the trowel. The Permashape® blade is also given true beveled edges, allowing the trailing edge of the trowel to glide gently over the surface of the concrete, greatly reducing surface aggregate popping. These are only a few of the reasons why Marshalltown's Permashape® is the best trowel made today.
