material
First look at the door leaf filling material, is it filled with solid wood? Then look at the material of the door cover. Most merchants use density board, but solid wood composite board is more stable.
flatness
The flatness of the wooden door surface largely reflects the quality of the wooden door plate and the quality of the manufacturing process. I don't need to say more, just touch and observe.
thickness
Generally, the thickness of the door leaf of the standard suit door on the market is 40mm, and the wooden door that is too thin has poor sound insulation and no texture. The thickness of the door leaf of the magnetic mute suit door will be 45mm, which enhances the sound insulation effect of the wooden door.
Splicing place
High-quality wooden doors are very delicate in surface treatment, and almost no traces of splicing combination can be seen, which increases the aesthetics and at the same time, cracks and dislocations are not easy to occur during use. Fine and beautiful splicing, well-made decorative pieces, extra points!
certificate
It is often the simplest and most direct way to look at the relevant certificates of store promotion. Product certificate, grade environmental protection certificate and design patent are all bonus items.
