High strength: use high strength industrial polypropylene, polyester, nylon and other synthetic fibers as raw materials, with high original strength. After woven into regular interweave structure, comprehensive bearing capacity further improved.
Durability: synthetic fiber is characterized by its resistance to denaturation, decomposition and weathering. Can maintain its original characteristics for a long time.
Corrosion resistance: synthetic chemical fiber generally has acid resistance, alkali resistance, moth resistance, mold resistance.
Water permeability: Woven fabrics can effectively control their structural pores to achieve a certain amount of water permeability.
Convenient storage and transportation: because of its light weight, it can be packed according to certain requirements, so it is very convenient for transportation, storage and construction
The quality is not affected by the temperature difference of ~-30 ℃;
