Rubber U-Channel Edge Trim

For edge interfaces where adhesive-based bonding is not feasible due to surface contamination, high shear loads, or disassembly requirements, the trim’s internal core structure — typically a continuous galvanized steel or aluminum clip insert — provides a self-retaining interference fit. The insert geometry is engineered to exert constant radial pressure against the substrate, even with thermal expansion or mechanical vibration.

Modern assemblies often involve dissimilar material transitions — such as metal-to-glass, plastic-to-aluminum, or composite-to-steel — where differential thermal expansion and galvanic potential present engineering challenges. Rubber U-channel trims act as an isolating interface, mitigating both mechanical incompatibility and electrochemical interaction.
