Bad weather conditions

Unpredictable weather conditions are one of the most influential effects to make industrial wood deformed. The suddenly rising or decreasing temperature can easily turn the original form of wood into another one.

Normally, in the harsh winter, the cold weather makes wood shrink; and, when summer comes, wood products will be swollen. This sudden and frequent change is the cause of the warped and cracked industrial wood products.

Poor quality of wood

If you use low-quality wood improperly during the installation and arrangement in your apartment, it is inevitable for all of you to deal with the breakage as well as the warping of the wooden products.

The reason is that the fiber connection in this wood type is loose and easy to be affected by the harsh weather conditions. You’d better choose the wood in higher quality to avoid the problem in advance.

Wood which is placed in the space with high humidity for a long time will also be deformed. The ideal moisture content of wood products at the factory is only 8-10%.

Therefore, when being put in the environment with higher humidity,  wood is easier to be warped.

Destruction from insects

Insects such as carpenter-bees and ants love living in fiber what lead to loose fiber connection in the wood. Moreover, if these kinds of insects are there, it is inevitable for swarms to destroy the wood products.

Problems during the arrangement and processing

Various types of industrial wood are deformation-prone. Only light movements will make the wood warped right away. Moreover, if the edges of the wood products deviate from the original design frame or tray, wood warping is unavoidable.
