1. Look at the profile section
The profiles of sliding doors are divided into two types: aluminum-magnesium alloy and secondary aluminum. The profiles used by Ouze sliding doors are made of aluminum, strontium, copper, magnesium, manganese and other alloys, which have great advantages in toughness, and the thickness can reach more than 2mm; while the lower quality profiles are recycled aluminum , The toughness and service life are reduced.
2. Choose safety glass
Sliding door glass occupies the majority, and the quality of the glass directly determines the price of the door. Good choice of toughened glass, it will not hurt people if it is broken, and has a high safety factor. The appearance should be transparent and bright.
3. Listen to the pulley vibration
The sliding door has two upper and lower pulleys respectively. The upper pulley plays a guiding role, because it is installed in the upper rail, consumers often do not pay attention to it when buying. The structure of a good upper pulley is relatively complicated. It not only has a bearing inside, but also an aluminum block to fix the two wheels so that it slides smoothly in orientation and almost no noise.
4. Look at the sealability of the rubber strip
The popular adhesive strips on the market include PVC rubber, silicone and EPDM adhesive strips, which have better effects and will not corrode profiles, glass and core plates; in addition, EPDM adhesive strips have a flat surface, good sealing effect, vivid color, no color fade, no falling off and deformation .
