Three skills need to be mastered when buying small hardware accessories

In home decoration, some people tend to ignore the quality of small items or accessories in the process of purchasing them. Most of them think that these accessories do not play a key role in the decoration, and generally can not be on the countertop, so it does not matter if the quality is better or almost. In fact, these so-called accessories may seem insignificant, but they actually play an important role.

To choose the hardware, you need to open and close the pull several times

When choosing hardware such as slide rails, locks, etc., you should open and close and pull it several times to feel its flexibility and convenience. In addition, you also need to see whether the appearance is defective, how the electroplating gloss is, and whether the hand feels smooth or not. When purchasing a lock, you can also insert and remove the key several times to see if it is not smooth and whether it is easy to screw up. For comparison of similar hardware products, you can also weigh the weight by hand. The heavy weight products use better materials.

High quality wire copper core yellowish reddish

When purchasing wires, first look at whether there is a quality system certification, whether the certificate of conformity is standard, whether there is a factory name, factory address, inspection stamp, production date, and whether there are trademarks, specifications, voltages, etc. printed on the wires. Also look at the cross-section of the copper core of the wire, the color is bright, the color is soft, and the copper core is reddish in yellow, indicating that the quality of the copper used is better, and the yellowish white is a reflection of low-quality copper.

Another verification method is to use a wire end to bend repeatedly by hand. Anything that has a soft feel, good fatigue strength, a plastic or rubber feel elastic, and no cracks on the wire insulator is a premium product. You can also intercept a section of wire to see if its core is located in the middle of the insulation layer. What is not in the center is the eccentric core caused by the low craftsmanship. If the power is small, this kind of wire can still be safe. Once the power consumption is large, the thinner side is likely to be broken down by the current. At the same time, be sure to check whether the length and the thickness of the wire core have been tampered with when purchasing.

There should be a protective film on the surface of the plastic steel window

Considering the large window area of u200bu200bmost houses (such as closed balconies), the wall thickness of the profile should be greater than 2.5 mm when purchasing, the frame is embedded with special steel lining, and the thickness of the lining steel plate is not less than 1.2 mm. The inner cavity is a three-cavity structure, with a closed drainage cavity, an isolation cavity, and a reinforced cavity, so that the windows will not be deformed after decades of use. The surface quality should also be paid attention to. The surface of good quality plastic steel doors and windows should have a protective film, and the user should tear off the protective film before using it.
