Mesh-Bead Duct Plate Roll Forming With Anti-Sag Roll Support

The invention uses a mesh-type bead structure formed on the metal plate surface, creating a porous-like three-dimensional pattern that provides structural strength without requiring increased material thickness. The intersecting beads form a grid pattern that distributes and absorbs stress throughout the surface, achieving reinforcement while maintaining lightweight characteristics.

The invention employs curved bead profiles with rounded contours instead of flat or sharp edges. The spherical or semi-spherical shape of the beads provides better stress distribution and absorption capabilities, enhancing the duct's strength-to-weight ratio by utilizing geometric curvature to reinforce the structure.

The mesh-type bead pattern creates a porous-like structure that provides high strength-to-material-ratio, allowing the use of thinner metal plates and reducing material costs while maintaining or improving duct strength through the geometric reinforcement of the intersecting bead pattern.

The curved bead profiles enable more efficient stress distribution, allowing for reduced material thickness and lower manufacturing costs while achieving the required strength levels. The spherical geometry provides natural stress concentration points that enhance structural integrity without additional material.

The mesh-type bead structure creates an visually appealing pattern that resembles porous or grid designs, providing both aesthetic value and structural reinforcement. The intersecting lines form a regular geometric pattern that is visually attractive while maintaining strength-enhancing properties.

The invention transitions from simple linear beads to a more complex asymmetric mesh pattern where beads intersect at various angles and positions, creating a visually interesting surface texture that enhances aesthetic appearance while providing multi-directional stress distribution for improved strength.

The mesh-type bead pattern creates a porous-like three-dimensional surface structure that provides vibration absorption capabilities similar to porous materials. The irregular pattern and air pockets within the bead structure help dampen vibrations from earthquakes or machinery while maintaining manufacturing simplicity through roller-forming processes.

The curved bead profiles provide better vibration absorption compared to flat surfaces. The spherical shapes act as natural vibration dampers, absorbing and dissipating vibrational energy through their geometric form while maintaining the simplicity of the rolling formation process.
