Anular Corrugated Steel Pipe

Anular corrugated steel pipe (CSP) is a type of corrugated steel pipe that is shaped like a ring or annulus and is commonly used for culverts, storm sewers, and other types of drainage systems. It is made of corrugated steel sheets that are rolled and welded together to form a circular or annular shape. The corrugations in the steel sheets provide strength and stiffness to the pipe, while also allowing it to be flexible enough to bend and conform to the shape of the surrounding terrain. 

Anular CSP is typically used in transportation and infrastructure projects because of its high strength-to-weight ratio, corrosion resistance, and ability to withstand large loads and high levels of stress. It is also often used in agricultural and residential applications to drain excess water from low-lying areas.

Our metal corrugated pipe have greater strength, widely used in highway and railway stormwater culvert.


Wall thickness:3.0mm-5.0mm

Corrugation:125mm×25mm 150mm×50mm 200mm×55mm

Depth of cover

The minimum allowable depth of cover is the largest of:

For roads H=B/8+0.2(m) H=B/6(m) and not less than 0.6(m)

For railways H=B/4 and not less than 0.6(m)

There is a possibility to reduce depth of cover provided that suitable checking calculations will be made.
