Quality Control

Savannah Wood adheres to rigid quality control standards that are constantly monitored both in-house and independently by a third party.

Our plant carefully follows the American Wood Protection Association’s (AWPA) “Standard Quality Control Procedures for Wood Preserving Plants”.

Quality control begins when the plant operator completes a dated and consecutively numbered “Treating Sheet” for each charge (treating cylinder load) that shows the description and quantity of wood to be treated and provides a step-by-step procedure for calculating the proper amount of chemical to be injected into the wood.

Before any calculations are made, the treating solution strength is determined by an Oxford LX3500 X-ray Analyzer.

The Treating Sheet requires that a calculated final retention be computed. The calculated retention is periodically checked by taking boring samples from the treated product and analyzing them with the Oxford LX3500 for accuracy of calculated retention. Any charges that fail to meet the required chemical retention are re-treated.
