1. Firstly, there is a canopy installed, allowing rainwater to directly pour onto the door;
2. The expansion and contraction of door panels are not only affected by the natural environment, but also related to the degree of deformation of the material itself;
3. Materials with smaller deformation can be used, and the moisture content of the materials can be well controlled;
4. According to the local natural climate conditions, the wood used for producing door leaves needs to be dried and allowed to regain moisture for at least a week, giving the material a sufficient curing period to stabilize its moisture content at around 12% before starting the cutting process.
5. In addition, the moisture content of materials during the production process should also be well controlled. From cutting to semi-finished products until painting, it is necessary to ensure that the material does not absorb moisture and the moisture content does not increase. This requires the materials to be placed in a constant temperature room in a timely manner to maintain the moisture content of the wood from increasing.
6. In terms of production technology, by using different knot connection structures, anti deformation adhesive strips are added to the most important deformable parts of the door structure to minimize deformation.
