 *With a multitude of pipe sizes, shapes, gages, coatings and materials options, corrugated steel pipe (CSP) products offer specifiers and users the greatest versatility and flexibility in designing drainage solutions to best fit their projects’ exact requirements.  Our CSP products provide the highest service life, strength and hydraulic properties.
 
*Corrugated steel pipe has distinct advantages over other maerials fors its light weight, strength, easy to installation, low maintenance and adaptability to various field conditions.

*Corrugated steel pipe is manufactured from steel coil, corrugated and formed into pipe.The coating is made  by Hot dip zinc technology. Steel thickness and corrugation profile depend on the type of structure, height of cover and live load over the stucture.And also, our corrugated steel pipe can be producted according to customers' design and requests.  

Advantages: 
 1. High strength: 1.5 to 3 times stronger than cement pipe.
 
  2. Light in weight: only 1 / 15 ~ 1 / 5 of the cement pipe with the same diameter.
 
  3. Long service life: service life is more than 100 years.
 
  4. Low cost: when the span (diameter)≥1m, the bigger the span is, the greater the economic benefits will be.
 
  5. Convenient in construction: no need large machineries, only a little hand works is required on site.
 
  6. Good axial flexibility: suitable for the places where the foundation settlement is serious.
 
  7. The construction period can be shortened in half, hence saving labor costs.
 
  8. Help to improve the “faulting of slab ends” phenomenon of land-based structures at the junction with the embankment, and improve the driving comfort.
 
 
  9. Environmental protection and low-carbon release: reduce or completely abandon using conventional materials such as cement, sand, gravel and timber, this is conductive to environmental protection and reduction of carbon emissions.
 
 
  10. Easy maintenance: maintenance free in a considerable part of the environment, hence reducing the operation costs significantly.
