When sourcing wood veneer doors, you must prioritize the core material, which is typically solid wood, MDF, or particle board. For high-end projects, a solid wood core (engineered wood) provides the best stability. The veneer thickness should ideally be between 0.6mm and 2.0mm to allow for future refinishing. Additionally, ensure the surface treatment uses UV-cured paints or PU coatings for superior scratch resistance and color retention. Always verify the moisture content is maintained between 8% and 12% to prevent warping or cracking during cross-border transit.
