White pine, also known as fir pine and spruce, is now one of the precious tree species in China. White pine is a perennial tree, which can grow up to about 45 meters. It has strong adaptability to soil and can grow on cinnamon soil, red loess and red limestone soil. However, it has strict requirements for soil moisture, and is not resistant to drought, barren, salt and alkali, and poor drainage. Pinus armandii is hardy. It can grow normally at low temperature (minus 7-10 ℃) and also at relatively low temperature (maximum minus 31 ℃).

Pine formula has good stability, stable quality, durability, long service life, strong practicability and durability. As long as the construction method is correct, it can show good use effect. There is no need to worry about corrosion, strong external force damage, loosening or shaking. The overall service life is longer and the construction quality reaches a better standard to avoid unnecessary trouble to the construction project. In addition, Baisongfang has strong elasticity, strong permeability and good thermal conductivity.
White pine has good corrosion resistance in use, and the effect of outdoor use is very good. Don't worry about corrosion in various environments. Even in wet environment, it still shows stable corrosion resistance. In the natural environment, it has strong corrosion resistance, space corrosion, humidity and chemical corrosion resistance. Professional manufacturers will also carry out anti-corrosion treatment, and the anti-corrosion capacity will naturally improve.
White pine has good physical properties, such as light wood, moderate toughness, low strength and seismic resistance, and low corrosion resistance. But white pine has good durability and is not easy to warp. Of course, white pine has many applications in construction sites. In civil engineering, this kind of timber is often used as the beam of concrete formwork, which can strengthen the building formwork.
Of course, white pine also has some disadvantages, belonging to cork. The overall material is soft, not as strong as hardwood, and easy to crack and deform. This is because of its high moisture content, so the pine must take moisture-proof measures. In the processing design, the pine must be dry, otherwise it is easy to crack during the processing. As the resources of white pine are becoming less and less, the production and processing of white pine depend on imports, and the price of white pine increases year by year.
Therefore, white pine construction wood can be said to be very good construction wood, which is widely used. Therefore, we can often see some civil buildings with higher quality, which are deeply loved by everyone.
