GripMetal strengthens composite action in bending, allowing beams and panels to span farther without increasing depth. Better stiffness. Fewer columns. More competitive mass timber buildings.

GripMetal transfers tensile and shear capacity into mass timber components, allowing manufacturers to use species and grades previously unsuitable for structural applications.

Unlike adhesive systems that require press and cure time, GripMetal creates an instant mechanical bond. Press it once. Move on.

GripMetal makes mass timber assemblies more ductile by preventing sudden, brittle separation between laminations. When timber fibers begin to crack or slip, the mechanically interlocked micro-hooks continue to engage. Instead of a brittle failure, the assembly maintains integrity longer and fails in a more controlled, ductile manner.

Mass timber’s predictable char layer protects the embedded GripMetal surface, keeping it insulated from rapid temperature rise and preventing the premature failures associated with exposed metal connectors. Because GripMetal lies fully within the wood, it maintains mechanical interlock deeper into a fire event without introducing a heat-bridge from the surface.

Adhesive bondlines introduce variables; surface preparation, moisture, temperature swings, cure behavior, and long-term aging that can affect the consistency of shear transfer. GripMetal eliminates that dependency. Its mechanically embedded micro-hooks grip directly into the wood fibers, creating a stable, predictable shear-transfer interface that performs independently of environmental conditions.
