A sequence is a set of veneer leaves that have been sliced and stacked in the order in which they were cut from the log. The number of leaves in a sequence varies by species, cut, grain-orientation, and yield of the log.
In many instances, such as the door and stock panel markets, sequencing is not required for certain graded demands. In some of the commercial, higher volume graded markets, no two doors have to look alike, nor do panels in the stock panel world. Most architectural projects however require sequenced material to achieve the aesthetic and design intent of the project. Maintaining the exact sequence of veneer leaves is critical to producing high quality panels for architectural use. Leaves that are out of sequence can produce irregular pattern and color variance that can be very apparent on the finished product. Our quality control processes are designed to prevent this. When we receive a shipment of veneer, we put every log that requires sequencing on our grading tables prior to running it through our measuring line. It’s not uncommon to find errors in sequencing that could create big problems and significant delays farther into the process.
