Corrugated Steel Sheets
When a roll of steel is flattened, we see it is still soft, but when pressed into a tile shape, the same length of steel sheets will be deformed and bent due to its own weight, but the tile will not.
This is because its cross-sectional inertia moment becomes larger and the load capacity Increased several times, this is like folding a fan with paper when you were a child. Color steel tiles are one of the applications.
If this structural feature is made into steel sheets, it will become a very practical construction material in the construction of highway culverts, that is,
corrugated steel sheets.
However, using corrugated steel sheets alone is not very load-bearing. For example, in the following picture, a small-diameter corrugated steel sheets is easy to step on one foot, and it will be different if there are other objects around.
Corrugated steel sheets culverts, the stress principle is that the pipe body and the surrounding backfill soil are jointly stressed, forming a pipe-soil effect. This kind of structure is inexpensive, at least for field operations, the soil should be free of money.
