PP Welded Geogrid
PP welded geogrid is a kind of new environmental protection and green building materials, which is reinforced by reinforced fiber in polyethylene or polypropylene tensile belt, and then welded into "#" structure. It can be divided into uniaxial or biaxial bonding and welding geogrid. The product has the advantages of high strength, small deformation, corrosion resistance, long service life, convenient and fast construction, saving cost and so on. It can be paved, positioned and leveled, and can especially meet the use requirements of all kinds of permanent projects for more than 100 years.
PP welded geogrids have high tensile strengths due to its ribs are extrusion and stretching of the high polymer plastic. The intersection of the longitudinal and transverse ribs is welded with high frequency ultrasound to ensure the stable quality of the product and the effective locking of the grid to the soil. At the same time, the strength of the grating can change the tensile strength. Adjusting the number of ribs, grids are designed to different types and specifications. The strength of PP welded geogrids can be adjusted to meet the needs of different projects and technical specifications.
PP welded geogrids have high strength, low elongation (breaking elongation not more than 12%) and low creep. The reinforcement of grids strengthens the foundation, increases the bearing capacity, reduces uneven settlement and resists the formation of the soil damage surface. PP welded geogrids have good flexibility and maintain the performance of the geogrid.This material is continuously reinforced by strong stretching and double-sided clamping of transverse rib. It will keep geogrid's performance even through crack.
