products description :
1.material: Q235
2.thickness:1.6-4.5mm
3.diameter(span)500-2800mm
4.corrugations:68mmx13mm 76mmx25mm
5.anti-corrosion treatment :hot dip galvanized ≥ 63 µm second preservcotive (usually by coating asphalt or polymer coating)
6.Using the life: ≥ 75 years
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.
4.year-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
widely used in storm sewers nestable corrugated metal pipe
