Post-Tensioning Flat Duct, Concrete Corrugated Oval Duct

Post Tensioning flat duct specifications

This corrugated flat duct is formed by the round post tensioning tube directly. Its special corrugations, high radial stiffness well adapted for use as void former in. It is also being used as culverts and forms for concrete pipes, plinths and columns, used to reduce the cross section area and thus the weight of the structure. Approximately 40% weight can be reduced and favorable effect on foundation. With the concrete construction wall and slab thickness request, this flat duct is widely adopted in post tensioning industry. This is also our main ducts exported for overseas countries. With our patent extending technology, the flat duct surface can be protected smoothly. The flat tubes meet with structural design specifications for void former. It is a very rigid but yet light weight sheet metal tubing that without excessive deforming, withstands existing forces during the pouring of the concrete. The spiral seam is tight and no water from the concrete will enter the tube. We are the most professional and the biggest supplier in Chinese post tensioning ducts industry. The normal sizes for the flat ducts is as following, 20mm*90mm, 20*80mm, 20*70mm, these three are the most popular in the present. The thickness range is from 0.3-0.4mm.

Other sizes flat duct can be negotiated.

Concrete Corrugated Post Tensioning flat duct Application

On many construction projects like apartment buildings, parking garages, office buildings, industrial buildings, bridges and docks, schools and hospitals, the introduction of the prestressed protection flat duct will make it possible to use very long spans. The reduction in weight allows large areas and fewer columns which in turn will give technical economical and esthetic advantage.
