Precautions:
Precautions in the use of building square timber: the quality standards and inspection methods of logs vary greatly from country to country, and the manufacturers of building square timber are mainly divided into several types.
Quality of building square timber: All kinds of quality defects in the square timber itself are deducted from the original timber length or diameter grade according to the size and severity of the defects. The volume of each log after deducting the size of the defects is the net volume, and individual serious defects can also be combined to reduce the quality grade. Countries that use defective square wood quality include the United States, Canada and other countries.
