In the process of home decoration, some people tend to ignore the quality of the small pieces or some of the accessories. Most of them think that these "accessories" do not play a key role in the decoration, and generally can not get on the "counter", so the quality is better or almost does not matter.
Select the hardware to open and close several times
When selecting the hardware such as slide rails and locks, it should be opened and closed several times to feel the flexibility and convenience. In addition, you need to see if the appearance is defective, how the gloss is applied, and whether the hand feels smooth. When you purchase the lock, you can use the key to insert and pull it several times to see if it is smooth or not. If the comparison of similar hardware products, it is also possible to use a hand to rub a component, and a product with a heavy component is relatively good.
High quality wire copper core yellow reddish
When purchasing electric wires, first check whether there is a quality system certificate, whether the certificate is standardized, whether there is a factory name, a factory address, an inspection chapter, a production date, whether a trademark, a specification, a voltage, etc. are printed on the wire. Also look at the cross section of the copper core of the wire, the color is bright, the color is soft, the copper core yellow is reddish, indicating that the copper used is of good quality, while the yellow and white is the reflection of low quality copper.
Another verification method is that a wire head can be repeatedly bent by hand. Any soft touch, good fatigue resistance, strong plastic or rubber feel and no crack on the wire insulator are excellent products. You can also take a section of the wire to see if its core is in the middle of the insulation. What is not centered is the eccentricity caused by the low process. If the power is small, the power can be safe when used. Once the power consumption is large, the thinner side is likely to be broken by current. At the same time, when buying, be sure to see if the length and core thickness are not being used.
Plastic steel window surface should have protective film
Considering that most of the houses currently have large windows (such as balconies), the wall thickness of the profiles should be greater than 2.5 mm when purchased. The special steel lining is embedded in the frame. The thickness of the inner lining steel plate is not less than 1.2 mm, and the inner cavity is The three-chamber structure has a closed drainage chamber and an isolation chamber and a reinforcement chamber, so as to ensure that the window is not deformed for decades. Also pay attention to the surface quality, the quality of the plastic steel door and window surface should have a protective film, the user will tear off the protective film before use.
