Profiles:
To aluminum alloy as the upper, the so-called nano-orbit is with nano-scale plastic fillers with plastic extruded plastic profiles, by adding anti-UV additives, tougheners, to avoid long-term use of aging, fracture problems, coupled with the production process accuracy is easy to control, often the cost is much lighter than aluminum alloy, for the mid-bottom market and customers, is a good choice. Aluminum alloy track variety is more, surface treatment has oxidation, spraying, electrophoresis, raw materials to primary aluminum alloy on, many cheap aluminum alloy track is made of recycled materials, surface treatment to electrophoresis for the best, smooth surface, do not fade.
She pulleys: polyethylene, nylon, polyformaldehyde-based plastic wheelless class and with metal rings of the two categories: poor quality plastic pulleys are mostly recycled materials, the surface is dim and brown, it will not take long to break and aging, its pull ring one Like the use of ordinary wire bending, a long time will rust, pollution curtains, good quality she pulleys by adding ultra-fine fillers and additives modified plastic, product surface smooth and no burrs, friction resistance, anti-wear performance is better, hand pull light slip silent, Pull ring using stainless steel wire, static vibration grinding, the surface gloss is excellent, the texture is very good.
Installation code: generally using 0.5MM thickness of ordinary coating, pressure plate using recycled plastic, easy to rust and damage, installation code is a solid track guarantee, should use 1.0MM steel plate, the use of nylon pressure plate, surface strict use of acid washing, cleaning, scaling, cleaning process, coating solid, easy to install.
Rail cover: Generally cheap tracks are made of recycled plastic, the surface is dull and not tough, the excellent cover is made of high-quality ABS, the surface is smooth, the logo and the text is clear.
Packaging: General track packaging is simple and unpackaged, good tracks will use well-printed PE bags.
In the purchase is not greedy for the track cheap, from the above aspects to compare it, the track is the basis of the curtains, good track use smooth solid, can save you a lot of problems
