0.5mm Sheathing Duct For Bridge And House Building

China factory Metal Ducts for Post Tensioning System

Prestressed metal corrugated pipe

Prestressed metal corrugated pipe can be divided into two types, oblate pre-stressed metal corrugated pipe and circular pre-stressed metal, which is used in highway/railway bridge engineering, slope anchoring of helical prestressed corrugated pipe, as a new type of pore forming material, it is anti-acid, alkali corrosion, good sealing, no water seepage, no slurry leakage, high ring stiffness, not afraid of pressing, easy to transport for safekeeping, etc.

The appearance of the sewage pipe quality, the structure size, ring stiffness, local lateral load, flexibility and other technical indicators, in line with the GB/T9647-2003 national standards, JT/T529-2004 transportation industry standards, our products passed the national authoritative organization in the form of the examination.

Round tube and flat tube, which has anti-seepage, high pressure, high strength and flexible, and can ensure the quality of construction. It is widely used in various large and medium-sized Bridges. High-rise large-span buildings, dams, nuclear power plants, etc.

 Metal Duct

Application :

It has been widely adopted by modern construction, especially used in pre-tension or post-tension for concrete constructions as building materials, such as bridge construction, railway and highway construction, underground structures,buildings and channel
