Commercial vehicles

Commercial vehicles

The lightweighting advantages of Constellium aluminium solutions are critically important in commercial road vehicles due to the size of the construction and the added weight of cargo. 

Helping commercial vehicle manufacturers compete

Every kilo saved in the structure of a commercial vehicle increases its freight capacity and its profitability. However, as these vehicles are subjected to more extreme wear and tear, they have to be particularly robust, crashworthy, and corrosion-resistant.

Aluminium extruded profiles

Commercial road vehicle

We design and supply aluminium solutions and applications based on extruded profiles such as tippers and chassis units, curtain siders, rear door frames, trailer front-ends, side walls, and under-run side and rear protections.

HERKAL HK34®, XTRAL 728® alloys, tread plates

Our HERKAL HK34® alloy offers excellent mechanical properties for the floors and sides of tipper vehicles used to transport bulk products, from grain to building rubble. At just one-third the weight of steel, it affords freight operators an increased payload and cost savings when the vehicle is traveling empty.

Tighter safety regulations and a demand for lighter liquid transport vehicles make our XTRAL 728® a highly sought-after alloy. It combines high levels of formability with a capacity to withstand impact, enabling vehicles to comply with all the latest safety regulations. 

Commercial road vehicle

For the floors of commercial vehicles and refrigerated trucks, our “rice grain” tread plates combine lightness with resistance to abrasion and corrosion. “Rice grain" tread plates also enable vehicle manufacturers to minimize noise during loading and unloading of goods, thus adhering to the most stringent regulations, such as Piek specifications.

Our product offer is available in a variety of sizes, including thicknesses of 4 to 12 mm, widths of up to 2,500 mm, and lengths of up to 13,500 mm.

Aluminium sheets

The various aluminium processes that we have designed and perfected over years of working in the industry facilitate the creation of optimal parts that are strong, stiff, formable, durable and corrosion-resistant.

We have also developed a range of semi-finished products for equipment parts in vehicles such as truck tanks.


According to industry analyses, vehicle weight is proportional to fuel consumption and therefore CO2 emissions: a 5% reduction in vehicle weight translates into a 5% reduction in emissions.
