Q. |
What are the advantages in using R/C or Pl/Sl veneers? |
A. |
Plain Sliced veneers have a more uniform grain pattern. When sliced, this type of veneer is stacked in the sequential order of slicing and sold as one flitch. This allows each leaf of the log to be stitched back together to create a veneer that can be sequence matched and numbered at the press. This is essential for uniformity in high end architectural woodwork. This cutting method is slower than Rotary peeling, and is more costly. Rotary Cut veneer is recognizable by its wide or wild grain patterns. As the log is peeled on a rotary lathe, it can yield a sheet of venner wide enough to cover a panel. This is referred to as Whole Piece Face (WPF). Whole piece faces eliminate any splice lines and can eliminate some finishing issues. Rotary cut spliced veneer is the smaller pieces from the rotary lathe that are spliced together to make up the panel width. |

Q. |
Why is Shop Grade hardwood plywood not always available? |
A. |
Because Shop grade develops when on grade panels don't make grade, there is no consistant supply. Most manufacturers try NOT to make shop panels. |
|
Q. |
What is shop grade - (explanation of fall down vs manufactured)? |
A. |
See explanation above on fall down. Manufactured shop is produced by mills upon request of their customer. Customer can decide on what grade, type and number of defects, repairs, etc. |
|
Q. |
Why is shop grade so much cheaper than on grade? |
A. |
Items which are SKU'd as shop grade are purchased that way. Plywood mills can accumulate excess shop in production of their on grade panels. The mills can ship up to 10% shop grade with the on grade, and the rest is set aside. After accumulating certain amounts of shop grade, they will sell that material at a fair market value. |
|
Q. |
Why is there shop plywood in my on grade? |
A. |
Plywood mills unintentionally produce shop panels when making on grade. The mill is allowed to include a percentage of shop, industry standard being 10%, with the on grade panels. The mill will produce material upon request with "NO SHOP", but there will be an upcharge for that service. |
