We manufacture two main products for construction: round concrete form tubes (aka sonotubes) and paper dowel sleeves.

Round concrete form tubes are used to create columns you’ve probably seen a million times in a parking garage. Paper dowel sleeves are used to do the exact opposite.

Paper dowel sleeves are used to create a void or empty space inside the concrete. Need to run a rod or cables through the concrete? Use a paper dowel sleeve.

Paper dowel sleeves are spiral paper tubes, made the same way a toilet paper tube or paper towel tube is made, only paper dowel sleeves are made to fit your particular project.
