Main application of corrugated metal culvert pipes

1. For underdrains, tunnels, culverts and animal channels of highways (waterways)

2. For temporary bridges and the load bearing structures of bridges

3. For urban downcomers, storm sewers and waste water pipes

4. For pipe-laying in shared areas underground

Advantage

1.Our protucts has both rigid and flexible ;stucforce structure is reasonable force, load distribution ,has a certain resistance to deformation

2.The use of standardized designs,factory-scale production ;short production cycle.high efficiency.helps reduce costs and improve quslity .

3.on-site installation of speed ,short construction period ,social economic benifit.

4year-round construction.construction not subject to seasonal effects.not environmental impact.

 5.can effectively solve the freezing cold north area of concrete bridges and culverts due to repeated failure problems.

6.especially for loading soil ,expansive soil, loess and other special areas, to aviod distortion caused by uneven ground settlement of the culvert damage.

7.reduction of cement. sand,gravel and other conventional building materials used.environmentally significant 8.compared with concrete bridges and culverts,the same span of the corrugated steel bridge and lower total cost .

9.a small post maintenance work,maintenance and low cost.
