Panel-to-Frame and Stiffener-to-Panel Assemblies

High bond strength supports large panels and enhances stability.


Refining Assembly Technique to Meet New Challenges in Design

  • From construction facades to elevator walls, panel-to-frame and stiffener-to-panel assemblies provide the strength and support needed for demanding structural applications. Especially for decorative and load-bearing panels which are exposed to stresses and environmental changes, rigidity is required for a longer-lasting hold.

    These assemblies also involve bonding with dissimilar materials, which calls for a secure and durable attachment. 3M Industrial Tapes and Adhesives deliver fast, reliable bonding for a wide range of substrates, and improve the aesthetics of your end-product with their nearly invisible fastening.

    Learn how design challenges in panel assemblies can be resolved with 3M bonding and assembly solutions.
