What are the contents and requirements of metal culverts anticorrosion design?

The metal culverts pipe is a flexible structure. The metal culverts pipe has the excellent characteristics of lateral displacement compensation in the structure, which can give full play to the characteristics of strong tensile strength and superior defor

Corrugated metal pipe products have circular Corrugated metal pipe, elliptical Corrugated metal pipe, semicircular Corrugated metal pipe, etc., processing Corrugated metal pipe diameter range of 0.5m-8m, Corrugated metal pipe wall thickness of 2.0mm-8mm c

Steel corrugated pipe culvert is a kind of flexible structure. After it is built, Steel corrugated pipe culvert will form a combined structure with the surrounding soil.

Assembled corrugated metal pipe (DGHG) is a high-quality road decoration building material that replaces round pipe culverts, cover culverts, arch culverts and bamboo bridges.

Color coated steel coil classification(1)According to the use of the based material:cold-rolled steel coil, hot-dip galvanized steel coil, hot-dip galvanized alloy steel coil, hot-dip galvanized-aluminum alloy steel coil,electro-galvanized alloy sheet coi

Attention should be paid to the construction of metal corrugated culvert pipe,1. The length and corresponding position of the screw should be preset and processed attentively to ensure corresponding assembly.

After the bellows are rolled out, check whether there is trimming or fracturing on the buckle edge of the pipe, cut off a section, tear the buckle edge with pliers, and check the buckle.

The zinc layer on the surface of the steel blocks atmospheric corrosion to prevent the substrate from continuing to corrode and ensure the service life of the substrate. In addition, zinc is more active than iron. In the case of corrosion, the zinc layer
