Galvanized Culvert Pipes are customized by professional China Lucky Steel manufacturer, carefully study the drawings, accurately issue the length, diameter, wall thickness, wave height, viewpoint and other key skills, and request the construction company to process according to the planning requirements.

The steel coils should be carried out by a professional processing plant, and the steel plate materials used in the construction are selected for processing and forming of Q235-A hot-rolled steel plates, and the appearance requires hot-dip galvanizing anti-corrosion treatment, and the amount of hot-dip galvanizing is not less than 600g/m2, and the thickness is not less than 80um. Before galvanizing, the surface of the steel pipe should be sandblasted and rust removed, and it should be carried out indoors.

In the process of hoisting, transporting, loading and unloading, the metal pipes shall not be rolled, bumped into hard objects, and cannot be hit, so as to avoid the deformation of the bellows pipe wall or damage to the galvanized protective layer. When storing at the construction site, a cover-up method should be adopted to avoid rainwater soaking and deformation. The length of the steel pipe is adjusted according to the transportation method or processing equipment, usually made according to a section of 2 meters, if it is a large-diameter bellows, it needs to be rolled in pieces, the scale of a single piece is 1x2 meters, and the flange bolt hole is mechanically drilled after the rolling.
