1.It is capable of expansion and contraction, and it can be folded during transporation and sretched during constuction.it constitutes a stong lateral restraint and stiffness structure by fling with materials such as sandstone or concrete. 2 . It is formed by light material with stable chemical propertes which is rsisant to abrasion, photooxidation , acid, and alkali It is suitable for different soil and desert conditions. 3.It has a higher lateral limit, anti skid, and ant-deformation and can effectively enhance the bearing capacity of the roadbed and load distribution.
4. It can meet dfent engineering needs by changing heignt, welding distance, and other geometric dimensions. 5. It is convenient to connect and can improve construction speed.
