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 s reduce costs and improve quslity .

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

4.year-round nstruction 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.

uction of cement. sand,gravel and other conventional building materials used.environmentally significant.

pared 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
