Specification：Pipe diameter: 200-900mm. Length: 1-6m.Thickness: 1.6-2.7mm

High strength:It with more than 1.5 times compression strength than the concrete pipe because of the corrugation structure.

Easy for transport:The weight of the corrugated steel pipe is only 1/10~1/5 of same size concrete pipe, even can be carried by people without machine.

Long service life:The steel corrugated culvert pipe adopt 300-600g/m2 galvanization steel plate, normally its servise life is 50-100 years, if in the strong corrosion environment, painting asphalt on the in and out surface of the pipe, can enlong 20-50 years based on the normal service life.
