All timbers are treated with ACQ/CCA/CA in the treatment plantlocated in our factory in Shanghai Our treated timbers aremeticulously being processed by using vacumn pressure impregnationmethod. Treating timber provides long-term resistance to organismssuch as mites and termites that cause deterioration. It can prolongthe timber`s life-span by five to ten times. Timber that is leftuntreated or exposed to moisture or soil for sustained length oftime will become weakened by various types of fungi, bacteria orinsects. VS is our new technology and unique in Asia. The woodtreated with VS is called organic wood because it is non-toxic andenvironmental protective.


ACQ or Alkaline Copper Quartenary is a relatively new treatmentwhich is a water based solution which uses Copper to protectagainst rot and fungal attack and Ammonium Quartenary as apesticide. ACQ treated timber possesses most of the same qualitiesas CCA timber in that it can be used in inground applications.
Tanalith E or Copper Azole treatment is another new water bornesolution which again uses Copper as a fungicide and Azole as apesticide, it too can be used in inground applications and has mostof the same properties as CCA treated timber.
