Adhesive Bonding for Commercial Vehicle Body Building
UK vehicle converters, box truck builders, and trailer manufacturers are eliminating rivets and drill holes with structural adhesive tapes — cutting build weight, removing corrosion entry points, and reducing assembly time per vehicle. As a tesa Platinum Distributor Partner, we test your exact substrates and validate the process on your actual line before you commit. Read about how we work with body builders.
On one UK van conversion line, fitting 60 m of lashing rail took 3 to 5 hours and up to 300 rivets. Bonded with tesa® ACXplus, the same job took under an hour — no drill holes, no corrosion cells.
What Mechanical Fasteners Are Costing Your Build
Every rivet, bolt, and bracket is doing three jobs simultaneously: holding panels together, creating a corrosion cell, and slowing your production line. Our guide to replacing traditional fasteners covers the full case for switching — below are the five problems we hear most from commercial vehicle body builders.
Hundreds of Rivets Per Body
Each rivet is a drill hole, a potential leak point, and a corrosion site — multiplied hundreds of times across a single build. Every one requires drilling, deburring, setting, and sealing. That’s thousands of process steps per vehicle that adhesive bonding eliminates entirely.
Galvanic Corrosion at Every Fixing
Steel rivets in aluminium panels create bi-metallic corrosion cells the moment they’re installed. The corrosion is internal and invisible until it causes structural failure or warranty claims. Adhesive tapes form an insulating barrier that prevents the cell forming.
Dead Weight from Metal Fasteners
Hundreds of rivets, bolts, and brackets add dead weight to every build. In commercial vehicles that weight comes directly off payload capacity. A bonded joint needs no fasteners at all, so that weight comes off the build.
Assembly Time Bottleneck
Drilling, riveting, and sealing each fixing point is several separate operations. On the lashing rail job above, bonding cut the fitting time from 3–5 hours to under one hour. Adhesive tapes apply in a single pass with no secondary sealing — production throughput improves immediately.
Water Ingress at Fixing Points
Every drill hole is a potential leak. Sealant applied over rivets degrades and cracks under vibration and thermal cycling, allowing moisture into the panel cavity where it initiates the internal corrosion that is invisible until it fails. Adhesive tapes seal the bond line completely.
Body Building Applications with tesa® ACXplus
The tesa® ACXplus range is the tape family in tesa’s own UK application story on bonding load-lock rails for a commercial vehicle converter — a customer Austen introduced to tesa. Grades below are starting points — we run a full substrate analysis before specifying anything for your build.
Roof Skinning
Typical grades: ACXplus 7815, 7074, 7078.
GRP or aluminium sheet bonded to roof frames. Eliminates the rows of rivets that create leak paths, require individual sealing, and corrode from inside the panel cavity.
Side Wall Assembly
Typical grades: ACXplus 7065, 7074.
Composite and aluminium panel joining with no visible fixings. Produces the clean, unbroken surface finish that fleet operators and end customers expect on modern commercial vehicles.
Floor to Frame Bonding
Typical grades: ACXplus 7074, 7078.
Viscoelastic bond lines between floor decks and cross-members accommodate differential thermal expansion — the movement that loosens and shears mechanical fixings over time.
Lashing Rail and Load Track
Typical grades: ACXplus 7074, 7078.
Instant attachment to side walls and floor panels without drilling through the outer skin. Distributes load-securing forces across the full bond area rather than concentrating them at fastener holes.
Kick and Tread Plates
Typical grades: ACXplus 7063, 7065, 7066.
Interior protection panels bonded without through-fasteners. Adheres to powder-coated and painted surfaces where drilling would compromise the coating and initiate corrosion underneath.
Top Hat and Extrusion Bars
Typical grades: ACXplus 7074, 7078.
Reinforcement profiles bonded with distributed stress rather than point-loaded rivets. The viscoelastic tape absorbs road vibration that fatigues and loosens mechanical fixings in service.

Grade selection depends on your substrates, operating environment, and process. Use our adhesive selection guide as a starting point, or call us and we’ll specify directly after testing your materials.
tesa® ACXplus Acrylic Foam Tapes
The range used on the lashing rail job above and in tesa’s UK vehicle conversion application story. Available in High Resistance, High Adhesion, and Black Line series to cover the full range of commercial vehicle substrates.
High Resistance: 7074 (1000µm), 7078 (2000µm) — outdoor mounting; tesa rates both for cold shock down to −40 °C and 120 °C long-term.
High Adhesion: 7063 (800µm), 7065 (1200µm) — powder-coated metals, plastics, textured surfaces.
3M™ VHB™ for Structural Panel Bonding
Full structural bond for exterior panels, roof skins, and lashing rail installation — tested to commercial vehicle standards. Multiple formulations available for high temperature, low surface energy plastics, and conformable bonding to curved panels.
Key grades: 5952 (Conformable), GPH-110GF (High-Temp), LSE Series for difficult plastics.
Note: Use 3M 94 Primer for LSE plastics such as ABS and polypropylene.
How We Support Your Production Switch
Switching joining method mid-production is a risk. Our process eliminates that risk before you commit a single vehicle to the new method. See our tesa Platinum Distributor Partner status.
On-Site Production Line Trial
We run a controlled trial on your actual build — same line, same workforce, same substrates. You see the bond strength, application time, and finish quality before any commitment. Measured results, not manufacturer claims.
Full Substrate Analysis
We test your exact materials — anodised aluminium, GRP, stainless, powder-coated steel — before specifying any product. Cohesive failure and interface failure are both preventable. We specify the right grade and primer combination for your substrates.
Application Training for Build Teams
We train your operatives on correct surface preparation, primer usage where required, and application pressure. Most bond failures trace back to surface preparation, not the tape.
