Common Types of Wood Damage

KnotsMarks left by broken branches. They undermine structural strength and impair surface appearance.

Dry CracksOccur as wood fibers shrink during drying, generally extending longitudinally on the surface.

WarpageResult from fiber arrangement, humidity fluctuations and external force pressure.

Insect InfestationCaused by erosion from ants, bees, larvae and other insects.

Mold GrowthWood gets infected with fungi when exposed to humid surroundings.

Moisture AbnormityMainly induced by improper transportation, storage and construction operations.

Excessive DryingHappens when wood is long isolated by cement, bricks or kept in dry environments.

UV DegradationProlonged UV exposure first damages the surface, followed by cracking and embrittlement.

Chemical ErosionWood features strong absorbency. Strong acids and alkalis split fibers and form sticky residues.

Physical DamageCaused by collisions and irregular handling during transportation and loading.
