The "Inside Story" on THINWALL™ aluminum trailer technology

Only THINWALL offers the proven strength of double-welded, double-walled aluminum. Titan's exclusive patented processes and original designs produce today's most advanced smoothside trailer body for long life and efficient performance.

DOUBLE-WALL CROSS-SECTION
The THINWALL panel is a hollow-core extrusion that achieves high strength with light weight similar to the way that corrugation turns paper into a high-strength board. The inner wall is thicker than the outer wall to absorb load impacts and to prevent interior damage from penetrating to the outside. The aluminum web between the walls is integral to the extrusion, with no mechanical joining.

DOUBLE-WELDED ASSEMBLY
Titan patented an exclusive process that overcomes the challenges of machine welding very long aluminum panels. Titan completes the welding for one side of an entire THINWALL assembly – up to 53 feet long - in a single automated pass. Then we repeat the process on the other side. The result is highly consistent, 100% machine-welded seams inside and out. There is simply no stronger way to assemble an aluminum trailer body.

HORIZONTAL CONSTRUCTION
Extruded panels are easier to assemble when they stand upright, but Titan's horizontal interlocking panels gain extra strength and stability much like the walls of a log cabin. The end-to-end seams withstand flexing stresses better when the trailer rolls and twists over rough terrain. A horizontal structure also eliminates welding seams at stress points on multi-axle rigs.

HEAVY-DUTY ALUMINUM
The 6061-T6 aluminum alloy used to produce THINWALL extruded panels was specially selected for its excellent wear factor – far superior to conventional aluminum sheet used in many trailers. Its rigidity and workability also make it an exceptional material for trailer bodies.

THINWALL FLOORS
The success of the THINWALL side panel led to Titan's application of the same technology to create a high-strength low-weight floor panels for aluminum tipper trailers and semi-dumps. Naturally, THINWALL floors use a heavier grade extrusion than sidewalls require, but their end-to-end strength and long-wearing durability deliver on all the advantages our customers have come to expect from THINWALL.

THINWALL ROLLED PANELS
To build the world's first hollow-core aluminum tub dump, Titan developed another original manufacturing process to roll standard THINWALL panels into the distinctive profile required for tub assembly. This unique body construction provides aggregate haulers with increased load capacity, improved visibility and a lower centre of gravity for maximum stability on the road and when unloading.
