[China Aluminum Network] plastic aluminum blinds selection skills:
First, observe the color: the leaves, all accessories including wire racks, adjustment rods, pull wires, adjust the small accessories on the rod, etc. must be consistent in color.
Second, check the degree of finish: feel the smoothness of the blade and the wire frame by hand, and the product with good quality is smooth and smooth, and there is no sense of stinging.
Third, open the curtain to test the opening and closing of the blade. Rotate the adjusting rod to open the blade, and the blades should maintain a good horizontality, that is, the spacing distance between the blades is uniform, and the blades are kept straight and have no sense of bending up and down. When the leaves are closed, the leaves should agree with each other without any light leakage.
Fourth, check the degree of deformation: After the blade is opened, the blade can be pressed down by hand to force the blade to bend, and then quickly release the hand. If the leaves quickly return to the horizontal state, no bending occurs, indicating that the quality is qualified.
Fifth, test the automatic locking function: When the blades are all closed, pull the cable, you can 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 locking function.
