Not a timber can make wood doors, it has its special material requirements. First, the requirements of internal and cost estimator to replace deck boards external stress balance timber, cum easily deformed, as well as to determine the physical and chemical properties of wood, in line with the principles of mechanics offset. This is because only one side of the leaf independent suspension fixed point, therefore, we must use those natural wood as a raw material for manufacture.
The selection of tree species in the solid wood door is wide. All wood products are water-absorbing, deformed. The problem is that the standard range must be in the state of deformation of. Due to how to build how to build a fence with pre built p differences in regional climate, the relative moisture content of air is different, therefore, requires wood moisture content is also different. To use wood doors according to the local relative air moisture content, kiln-dried to determine the value of the moisture content, conventional manufacturers generally use wood kiln dried moisture content of 10-12%. Why the South to the North on wood products deformation crack, so the reason.
