The domestic brand Conch is better. According to prices in 2011, taking *** extruded profiles as an example, conch is about 1,200 yuan more expensive per ton than Liaoshen.

The main difference between the two is the formula. Liaoshen profiles are softer.

But Liaoshen has developed well in recent years and has also produced a high-end brand called Zhide. The quality is much better than ordinary profiles. The color and texture look a bit like American Christo.

If you use it at home, you won’t be short of money on conch. But Liaoshen can also be used. No problem. They are all exempt from national inspection.
