Metal Culvert is an alternative to round culvert, arch culvert and road bridges high-quality building materials, can be used on road and rail cross passages, tunnels, culverts, drainage channels and bunkers and other projects.

Metal Culvert was born in 1784 in the United Kingdom; 1896 United States took the lead in research corrugated steel culvert, and the first for culverts; 1913 in Edinburgh, Scotland, UK waveform steel used in irrigation; 1923 American Railway Engineering Association in Illinois central Railway tested Metal Culvert channels; 1929 Canada will corrugated steel culvert for coal; 1931 Australia referred to eight meters automotive channel; 1948 U.S. installed in Shanghai's Pudong district diameter corrugated steel culvert 1 meter was used for military sidewalk (September 1998 excavation). After one hundred years of foreign research and application, the technology of Metal Culvert is mature.

Application has been extended road culverts, channels, bridges, water seepage wells, temporary pavement, the old bridge and culvert repair. Municipal drains, municipal co-ditch, coal pipelines and other fields.

Applications from abroad situation, corrugated steel culvert with applicable capabilities, instead of the traditional approach has a great advantage, the application has a promising future.
