Why are pine formwork used more on construction sites?

    The common materials of building formwork are pine, fir, cypress and so on, and pine is more popular. As the name implies, pine building formwork is a building formwork made of pine. The pine itself has rosin, and the color of the wood is yellowish. When the air is high, the wood will absorb water and expand, the natural air drying is more difficult, and the wood strength is higher.
    However, after a series of processing, such as drying, degreasing, bleaching and so on, the hardness is high and will not be deformed by external force. Therefore, pine is an ideal raw material for building formwork.
    Pine building formwork is favored by the construction site, because the building formwork is generally made of pine, usually made of high temperature and high pressure, and the flexural strength is more than twice that of ordinary wood.
