The vigorous development of geogrid in china is beyond the expectation of many of us. The new building materials introduced from abroad in 1990s are widely used in various subgrade and pavement and civil engineering with high strength requirements. With the continuous expansion of market demand, the production enterprises also appear like mountains and fields. The fierce competition leads to the appearance of various quality levels and prices. How should consumers choose?

Adhere to the use of quality to develop the market, do not engage in price war with peers, because the final outcome of the price war is to lose and hurt, and customers eventually become victims. Price war will inevitably affect the quality of products. In order to reduce the cost, we will use the method of reducing the specification of raw materials to save data cost, which will directly lead to the decline of product appearance and strength.

The price of geogrid in china is different according to different raw materials and strength. The higher the strength is, the more expensive the price is. If the product fails to pass the factory strength test, the manufacturer of the person in charge will not leave the factory or leave the factory after type reduction. The quality of geogrid determines the engineering quality. The quality of geogrid is only one aspect. For example, the quality of filler used in construction will also affect the effect of geogrid.

The geogrid is divided into two-way geogrid and unidirectional geogrid according to the stress mode of products, and glass fiber geogrid, synthetic fiber geogrid, polypropylene geogrid and steel plastic composite geogrid according to the material composition of products. In recent years, polypropylene unidirectional geogrid has been widely used in the construction of old road subgrade, which can effectively prevent the uneven settlement of subgrade The reflection of longitudinal cracks and cracks in old pavement.

PE / PP geogrid is made of high molecular polymer by extrusion and biaxial tension. It has high tensile strength and is suitable for all kinds of soil. Its performance index is better than that of UN stretched geogrid. It is one of the ideal reinforcement materials now. The grid can be widely used in highway, municipal road, railway, aircraft runway and other subgrade reinforcement engineering, highway, railway and river coast reinforced soil retaining wall reinforcement engineering.
