Plastic aluminum shutters

Venetian blinds have good ventilation and ventilation performance and can adjust the indoor light intensity, which is especially suitable for a simple and bright indoor space. Plastic aluminum blinds are favored by consumers because of their non-fading, non-deforming, and heat-insulating effects. When selecting this product, you need to pay attention to the following points: 1. Color The entire curtain includes blades and all accessories (wire holders, adjusting rods) , pull the line) and adjust the small accessories on the stick to maintain the same color, indicating that the production process has passed. 2.Smoothness Feel the smoothness of the blade and wire frame by hand. The product with good quality should be smooth and flat, with smooth edges and no sensation of stinging hands. 3. Opening and closing function Turn the adjusting blade to open the blade. The good product should maintain a good level between each blade, that is, the spacing distance between the blades is uniform, and each blade is straight and has no sense of bending up and down. When the leaves are closed, the leaves should agree with each other without any light leakage.
4. Anti-deformation degree After the blade is opened, the blade can be pressed down by hand to force the blade to bend down, and then quickly release the hand. If the blades quickly return to the horizontal state, no bending occurs, indicating that the quality is qualified.
5. Automatic locking function When the blades are all closed, pull the cable to roll up the blade. Pull the cable to the right at this time, the blade should be automatically locked to maintain the corresponding rolled up state, neither continue to roll, nor loose. Otherwise, there is a problem with the curtain lock function
