Issues regarding the selection of various types of floating pads

We have consulted several manufacturers of floating trays; currently available options include hexagonal aluminum alloy floating trays, as well as those in a triangular or grid pattern. Is there a significant difference between these various designs? That one is relatively reliable; could those who have used it give some advice?
All kinds of structures are fine! ! ! There are mainly a few points to note: first, the structure and material of the sealing strip ； The second is the manufacturing method of the oil measurement port, etc. For reference only! ! ! ! :handshake :victory:
The prefabricated aluminum internal floating roof features a grid structure that is more rational than other types, offering convenience for use and maintenance as well as improved durability. The hexagonal structure is prone to breaking due to the concentrated stress at the center point.
The character-shaped row structure we use works well.

Structurally, the new buoy-type assembled inner floating disk breaks away from the traditional structural pattern of inner floating disks. By applying biomimetic principles, the skeleton of the inner floating disc takes on a \"spider-web\" shape; buoyancy elements are installed within this radial framework, causing the floats to arrange themselves in a regular hexagonal pattern. This approach **increases the structural strength of the floating disc and ensures that the buoyant force per unit area remains uniform.
Among these styles, the grid pattern is relatively the better choice. The hexagonal internal floating roof that was just designed for an oil company has more buoyants, but in terms of durability, it’s not as good as the grid pattern. However, this also depends on the needs of the user.
While ensuring buoyancy, the smaller the float and the more evenly it is distributed, the better.
The best design for a structure is to allow only the buoyant force to act on the float, with no other forces applied.
Our factory’s 3,000-cubic-meter gasoline storage tanks use hexagonal shapes. The aluminum alloy inner floating discs designed for these tanks are very light; as long as the sealing is proper and the medium does not come into contact with the discs and cause corrosion, the buoyancy is designed to be 200%, so there are generally no problems
A 2000 CBM tank is a small storage tank. The strength and cost of various aluminum alloy floating roofs vary little. For the design of aluminum alloy internal floating roofs, both international (API650) and domestic design requirements stipulate that a 200% buoyancy factor must be provided, assuming that the specific gravity of the stored medium is 0.7. In other words, the designed liquid plane is basically near the central plane of the buoy (this is different if Honeycamb is used). The use of a hexagonal structure as the framework for internal floating roofs (with a diameter greater than 60 meters) seems to have no precedent. If the manufacturer can provide the structural stress analysis results for the internal floating roof, the poster will find that a grid structure is the better choice.
