The aluminum honeycomb cores connected to each other are like a myriad of I-beams. The core layer is fixed in the entire surface of the board to make the plates more stable. The wind pressure resistance is much better than that of aluminum slabs and aluminum veneers.
The center of the polypropylene honeycomb panels is an aluminum hexagonal honeycomb with a low density (about 3 to 7 kilograms per square meter). The polypropylene honeycomb panels are 1/5 of the same thickness of the same board, 1/6 of the glass, and aluminum. 1/7, greatly reducing the building load and cost, because the middle interlayer contains a lot of ai
