Truck & Trailer
Save weight. Make stronger. Reduce Wear.
There is an intense push to take weight out of today's vehicles. In trucking, every pound of the truck and trailer is a pound that can't be hauled for revenue. Lightweighting also increases performance and efficiency. Although some companies are moving to all aluminum construction, for most the answer lies in multi-materials.
Multi-materials create new challenges for engineers. Gluing, fastening and advanced welding techniques provide gains in some applications, but most often these solutions are not as simple and easy to implement as structural metallurgically bonded transitions. In fact, Spur has been providing top trailer manufacturers roll bonded aluminum-to-steel transitions for years. Traditional welding allows the structural transition to be welded to both the aluminum and steel members. The resulting joint has little galvanic corrosion potential and is stronger than the aluminum.
- Aluminum trailer cross members to steel frame rails
- Aluminum trailer decks to steel chassis
- Wear resistant clad surfaces to lightweight materials
- High strength interfaces to steel hardware
- Tubular interfaces for low weight universal joints and drive lines
Spur's structural transitions are available in a wide range of materials and thicknesses. Most often, 1050 aluminum is used on top of A36 steel as to provide a highly weldable and strong transition. Alloy aluminums can be used for applications requiring machining.

Start by understanding the materials of your Spur weld transition and ensure they are compatible with the respective materials of your structure. Pick compatible filler rod or wire.
Do not exceed 350C / 662F at the bond line or damage to the insert may result. Start by welding the aluminum side first. Keep weld edge 1/16in from bond line.
