Which statement correctly describes veneer logs compared to grade logs?

Which statement correctly describes veneer logs compared to grade logs?

• A. Veneer logs require clear surfaces and soundness, while grade logs can have some blemishes and are used for various products
• B. Veneer logs have blemishes; grade logs require perfect surfaces
• C. There is no difference; they are the same
• D. Both types must be rot-free and are used for identical products

Answer: (A)

Veneer logs are chosen for producing thin, continuous sheets in plywood, so they must have clear, sound surfaces with no internal defects that would show up in the veneer. Defects like large knots, cracks, or rot would ruin the peeling quality and veneer yield, making those logs much less valuable for veneer production. In contrast, grade logs are assessed for solid wood products and can tolerate more surface blemishes because they’re sawn into boards where defects can be avoided or minimized in the final product, and they serve a broader range of uses. That distinction—high surface quality and soundness for veneer to yield good veneer sheets, versus allowing blemishes for various solid-wood products—explains why the statement about veneer logs needing clear surfaces while grade logs can have blemishes and are used for different products is correct.
