Recently, the capital Steel Corp Jingtang company adopted nonwovens to greet the factory area.

It is understood that the greening engineering planting area is divided into four levels.

The top layer is backfill soil, the second layer is nonwovens, followed by gravel, and the last layer is nonwovens.

Its role is to isolate or slow down salt and alkali and other harmful substances into the plant roots, to protect the normal growth of plants. The two layers of non-woven fabric in the middle of the gravel will play a role of buffering and drainage.

Nonwovens are mainly used for greening vegetation and sand fixation, so that the wind can not get rid of sand, reduce the damage to equipment and products in the plant area, and provide conditions for production and construction.
