We plan to purchase a batch of hot-dip galvanized steel sheets. Given that our previous suppliers failed to meet our material performance requirements, we have strict standards for the corrosion resistance, galvanized layer quality, and processing performance of the sheets this time. Can you provide a detailed material certificate that meets the relevant standards to ensure that the chemical composition and mechanical properties are up to standard? Can you guarantee the bending performance? We need to confirm that when the sheet metal is processed at a specific bending radius, there will be no zinc layer peeling or micro-cracks.
I purchased galvanized steel sheets from their company earlier this year. They provide raw material certificates with clearly stated chemical composition and mechanical properties (yield strength, tensile strength, etc.), fully compliant with national standards. The adhesion between their material substrate and zinc coating is excellent; as long as your mold and process parameters are appropriate, there have been almost no instances of large-area zinc coating peeling or noticeable micro-cracks during bending.

If you're still concerned, I strongly suggest they send a sample for testing first. That's what we did; we bent it a few times, tested the zinc coating, and once the results came back, we had a clear understanding of its quality.
Why should an arch be reserved during the construction of corrugated culverts?
Corrugated culverts buried in ordinary soil foundations often experience a certain degree of subsidence after a period of time, and the subsidence is usually greater in the middle of the pipe than at both ends.
Therefore, the corrugated culvert pipes laid under the embankment should have an upward pre-camber in the middle. The pre-camber is determined by a comprehensive consideration of factors such as the potential settlement of the foundation, the longitudinal slope of the culvert bottom, and the height of the fill. It is usually 0.3% to 1% of the pipe length, and the maximum is no more than 2%, to ensure that no depression or landslide occurs in the middle of the pipe.
