 Prestressed plastic bellows is a single-wall bellows extruded by a plastic extruder by high-density polyethylene (HDPE) for post-tensioned prestressed concrete structures as a perforated pipe with prestressed ribs. It is an ideal alternative to the original metal bellows in bridge and building construction. Plastic bellows are divided into two categories: round pipes and flat pipes, which are connected in actual use by various types of plastic connectors. The raw material for prestressed plastic bellows is HDPE. Its corrosion resistance is far better than that of metals, not afraid of acid and alkali corrosion, it does not corrode itself, and can effectively protect the prestressed ribs from corrosion.

Plastic bellows as a prestressed post-tensioning method of porous material is an important part of the prestressed system, for a long time prestressed engineering using metal bellows as a pore material, in order to overcome the shortcomings of metal bellows poor sealing, easy damage, easy to rust, large friction resistance, but also in order to provide an additional anti-corrosion barrier for prestressed ribs, it is recommended to use polyethylene or polypropylene made of plastic bellows as a revolutionary product with bonded post-tensioning method to improve the life of the structure
