About honeycomb girder made by ZZHZ

It is in the worksite operation that we realize a launching gantry between truss girder and box girder is needed, it is better if we can combine high stiffness of box girder and high wind resistance of truss girder, so we deign the honeycomb girder. The honeycomb hole allows wind to go through, and the web plate ensures a higher stiffness, as for why it is a honeycomb hole, it is a kind of craftmanship and it does not cost much.
