LN large diameter assembled corrugated culvert, galvanized metal corrugated culvert, high quality products
Characteristics of metal bellows
1 High strength, due to its unique corrugated structure, it is 15 times more compressive than cement pipes of the same diameter.
2 Convenient transportation, the weight of bellows culvert is only 1/10 to 1/5 of the same diameter cement pipe, even if there is no transportation equipment in a narrow place, it can be transported by hand.
3 long service life, steel corrugated pipe culvert is hot-dip galvanized steel pipe, so the service life is long, the life is 80-100 years, when used in a particularly corrosive environment, the steel with inner and outer surface bitumen is used. The bellows can be improved for more than20 years based on the original service life.
4 Convenient construction: Corrugated pipe culverts are connected by sleeve or flange, and can be customized according to the needs. Even unskilled workers can operate. The construction can be completed in a short time with a small amount of manual operation, which is quick and convenient. .
5 Excellent economy:
The connection method is simple and can shorten the construction period.
