Trailer Design Guideline > Economic and environmental aspects of using HSS in the trailer industry

Weight-limited cargo

When hauling weight-limited cargo, reducing the vehicle’s weight allows for a higher legal payload, so fewer vehicle-km are needed to transport the same amount of goods.
This results in even greater energy savings than for volume-limited cargo. Let’s take the example of a heavy flatbed trailer in the tables below. By using Strenx® 700MC instead of hot-rolled S235, you can achieve a tare weight savings of 929 kg, a 23% lighter chas-sis, and annual fuel savings of € 2,686 (about US$ 2,917). The reduced lifetime CO2 emissions are substantial, at 62.66 tonnes, considering the reduction in raw material input, longer service life and greater payload. In our example, the Strenx® chassis brings a total payload revenue increase of € 9,461 (about US$ 10,278) annually.
