If it is a high quality of sliding door hardware accessories are generally engineering plastics alloy chute and the orbit design, manufacturing and the perfect combination, the track is very important. And track quality is determined to have radian and pulley with a good, but to remind you that a good track, in strength design and the pulley surface smooth degree is very good, not more thick wall track good.
Now, the track of the sliding door is common cold rolled steel and aluminum alloy. Rail is not necessarily very good, but said that it should be an aluminum alloy, it is good too much rail, especially in the anti noise aspects is very prominent.
Of course, the pulley is an integral part of the sliding door, a few days ago, the market on the pulley material on the three kinds of plastic, metal and glass fiber. The first to introduce plastic pulley, pulley of the material is relatively hard, is relatively easy to break, after using for a long time, there will be a astringent, harden,, to push and pull feeling worse. Metal material has a lot of strength, and track contact, it will produce noise. The glass fiber has a very good toughness and wear resistance, and it is also very smooth, durable type.
When it comes to the attention of a point, whether the product has a stop block with the upper and lower rail positioning system, the bearing type pulley in the promotion, is not smooth...... This series of problems, in the exploration and understanding, can be a very good verification.
It used engineering plastics alloy slide in hardware accessories, it is very good, also has a very good application. In fact, no matter how large hardware accessories, in many things, plays a vital role. If you don't have the spare parts, the whole thing will not be used normally.
