Galvanized corrugated steel culvert pipe is made of corrugated metal plate or assembled by corrugated steel plate, widely used in highway, railway, tunnels, bridges and a variety of mine construction engineering. The pipe is thin, light and resistant to deformation, reducing the damage of bridge concrete structure caused by frost, especially suitable for the frigid permafrost region, soft soil roadbed and the high-fill foundation.
assembled galvanized corrugated steel culvert pipe composed of structural plate is ready for a variety of uses, including small bridges, underpasses, and stream enclosures. Structural Plate’s shape also helps maintain the natural environment into which pipes are installed. For example, the arch shape allows wildlife to pass through without difficulty and also leaves stream beds intact.
Assembly corrugated steel pipe adopt M20, 8.8 grade high tensile strength bolt and arched gasket, side seam and bolts are dealt with sealant glue, steel plate surface use hot dip galvanization.Spray pitch after finishing assembly. Pipe ends and slope adopt M7.5 mortar rubble, and pipe ends pour concrete with reinforced bars.

Advantages of assembled galvanized corrugated steel culvert pipe
Real engineering cost is lower than the similar span bridge, culvert
High strength: its compression strength is 15 times more than that of the cement pipe with the same diameter.
Production is not affected by environment. Large-scale factory production, lower costs, quality control
Reduction of cement, gravel, sand and other pieces of rubble or dosage, is favorable for environmental protection
Convenient transportation: the weight of the corrugated culvert pipe is 1/10 to 1/5 that of cement pipe with the same diameter, can be transported even if there is no transport equipment in a narrow place.
Long service life: made of hot-dip galvanized steel, the service life is up to 80-100 years.
Convenient construction: connected by sleeve or flange, and the pipe length can be customized according to customer’s requirements.
Small sections allow for minimal exposed excavation
Excellent economic performance: low construction cost, short construction period.
applications: It widely use in the culvert of highway and railway,passageway, foot bridge, tunnel,tempotaty road,drain line, various mineral tunnel and protective retaining wall.
