- Unsanded board is not suitable for applications that require tight thickness tolerances or a blemish free screen side.
- For products less than 2.5 mm, the board must be sanded.
- Thickness tolerance is defined as any individual point on a panel. The measuring device and technique are described in SAE J315.
Sanded Board
| Location | Range of sanded thicknesses available |
| Duluth | 1.5 mm (0.060") to 6.4 mm (0.250") |
| Phillips | Can be sanded at Duluth |
| Thickness Tolerance = +/- 0.13mm (+/- 0.005 in) | |

Use of Natural Products
- Superwood® automotive hardboard contains more than 97% natural fiber... compare that to any other material used for interior trim applications.
- In wet process hardboard manufacture, synthetic additives are kept to a bare minimum. The naturally occurring wood components are used to bond fibers together under heat and pressure. The result is a strong and stable product that is as natural as you can get.
- The natural fibers primarily come from forest residue, waste materials and recycled materials.
- Forest residue - waste material that is leftover from logging operations such as tree tops and branches
- Industrial waste - waste and rejected material from wood processing plants, recycled board, recycled pallets
Internal Recycle and Utilization of Raw Materials
- Process wastewater containing dissolved wood sugars is concentrated by evaporation to create 10,000 tons per year of wood molasses. This material is used as an adjunct for cattle feed.
- Trim waste, sander dust, and wood chip screenings are used as fuel to generate 50% (280 billion BTU per year) of the energy needed to make the hardboard product.
- Wood ash from generating energy is used as a soil amendment (750 tons per year) by area farmers. This program is managed by the Agricultural Extension Service.
- Bark, wood fines and dirt are reclaimed from the chip washing process and converted into compost at a rate of 2,000 tons per year.
Customer Recycling and Uses of Board Processing Waste
- Fuel for generating energy
- Landscaping / mulch products
- Livestock bedding
