Product Description:

Galvanized culvert pipe is also called metal corrugated pipe culvert or steel corrugated culvert, refers to lay buried in the highway, railway culvert under the screw   corrugated pipe, it is made of corrugated metal plate roll or semicircle corrugated steel plate made of makings of circular corrugated pipe, widely used in highway,   railway, bridge, tunnel, retaining wall and a variety of mines and the retaining wall of roadway supporting engineering of culvert (tube).


Compared with reinforced concrete culvert, corrugated culvert has the advantages of thin pipe section, light weight, easy transportation and storage, simple construction technology, quick assembly, short construction period and so on.


When building corrugated culvert, can be assembled into any length according to the need, when necessary, the pipe section can also be removed, moved to another place to build, in the lack of sand and stone material area or low foundation bearing capacity area, the superiority of the corrugated culvert is more significant.


Product features:

a. high strength, because of its unique corrugated structure, it is more than 15 times greater than the same diameter of the cement pipe compressive strength.


b. convenient transportation, bellows culm weight only with the same caliber cement pipe 1/10 to 1/5,   even in a narrow place without transport equipment, manual also can be transported.


c. long service life, steel bellows culm is the use of hot dip galvanized steel pipe, so the service life is long, the life is 80-100 years, in a particularly corrosive environment when used, the use of internal and external surface leach attached layer of steel bellows, can be increased in the original service life on the basis of more than 20 years.


d. convenient construction: bellows culm is the use of sleeve or flange connection, and can be customized according to the length,   even if not skilled workers can also operate, construction with a small amount of manual operation, can be completed in a short time, fast and convenient.


e. Good economy: the connection method is simple, can shorten the construction period.
