Likarolo tsa Sehlahisoa
PP biaxial geogrid e entsoe ka polymer ka extrusion, ho etsa poleiti, ts'ebetso ea ho phunya ebe ho otlolla ha longitudinal le transverse.Thepa e na le matla a maholo a thata ka lehlakoreng le leng la longitudinal le transverse, 'me sebopeho sena se ka boela sa fana ka matla a matla a ho jara le ho hasana tsamaiso e ntle ea ketane mobung, e loketseng ho matlafatsa sebaka se seholo sa motheo o sa feleng oa ho beha.
