Steel-wood doors were full of fashionable things a few years ago, but the filling of this door is mixed wood. If you can smell the pungent smell, the quality of the wood may not be enough, and the formaldehyde, benzene and xylene are exceeded. The thickness of the steel sheet material on the outer layer is insufficient or even too thin to cause deformation after impact. But at the time of purchase, sales people generally don't emphasize these details. It is not recommended to use steel doors for the entire family. Bedrooms, study rooms, children's rooms, can use more environmentally friendly wood doors, beautiful and more environmentally friendly, that is, the price is relatively high. However, the advantages of the steel-wood door itself are also obvious. For example, after almost two years of use, even the door of the bathroom will not be deformed by the damp, and the sound insulation effect of the door is quite good. Watching the stereo movie in the living room at night does not affect the rest of the elderly. Therefore, despite various defects, steel-wood doors still have a fixed market. The first is the surface paint of steel-wood doors. Its topcoat is divided into PV C and baking varnish. PV C feels good and looks good. It is selected by most consumers. In fact, the cost of painted steel wood door products is only tens of yuan more than PV C, but in the process of use, the paint surface is not easy to fall, and the durability is better. Followed by the frame, usually the steel door frame is divided into 4cm, 8cm, 10cm, 12cm, and it should be selected according to the thickness of the wall. Some small brands promise to install the package, but installing it on a 12cm thick wall with an 8cm frame will seriously affect the appearance. However, some installations that require more than the predetermined wall thickness will be charged 30-35 yuan / cm, which is best asked at the time of purchase. Again, the thickness of the steel plate and the environmental protection of the filled wood. According to the relevant national standards, the steel plate thickness of steel doors cannot be less than 5mm, but the products below this standard are everywhere, and consumers are not well-received. In terms of filling wood, the country has no regulations yet, and the environmental protection and moisture content of wood affect the quality of products. Therefore, when signing a contract for the purchase of steel doors, it is best to include the thickness of the steel plate, the quality of the wood, the frame specifications, etc., to avoid quality problems afterwards, and the business has been smashed. Of course, buying a regular brand product will be more assured.
