18709187805 Qinghai steel corrugated pipe culvert ￥ corrugated metal pipe culvert main features of the German town of Shaanxi lowest price of a steel corrugated culvert pipe, high strength: Because of its unique corrugated structure, above its compressive strength than cement pipes with diameter 15 times . 2, the construction is simple: the bellows flange connected, and because you can (up to 6m) can operate even unskilled construction with a small amount of manual operation can be completed in a short time according to need custom lengths, ie, fast and convenience. 2, easy to transport: light weight steel bellows, only one tenth of the same caliber cement pipe to fifth, even though no construction difficulties of transportation equipment in place, labor can also be transport. 4, long life: corrugated steel pipe culvert is the use of hot-dip galvanized steel, so life in general can reach 100 years, when used in corrosive environments and harsh conditions, the use of corrugated steel inner and outer surfaces of asphalt layer attached tube, can improve on the original basis over the life of about 20 years. 5, excellent economic characteristics: simple connection can shorten the construction period; lighter, easy to transport, plus a small amount of foundation construction, sewer construction costs are relatively low construction costs, such as construction costs to 600mm diameter concrete pipes and bellows of compared to the construction costs of the bellows cement pipe construction costs only about 90 percent of the time in traffic inconvenient place construction, artificial can save the cost of forklifts, cranes and other machinery and equipment.
