Metal Bellow / Bellows Pipe
Construction and Principle:
* Circular
* Wide application range
* High quality
* Safe

Our company cooperates with the Ministry of Communications to develop metal bellows. The product has absorbed the advantages of foreign products and reached the industry-standard National Industry (JG/T3013-94). It is widely used in highways, bridges, railways, and large-span prestressed concrete construction industry. Our product has superior product quality, good performance, and it is safe and reliable.

Circular Metal Bellows Material: K215-A(GB4175. ), sheathed galvanized steel strip (GB4175.2)
Circular Metal Bellows Appearance: Bellows look clean with no holes, no cracks, no release
