Economical and ecological factors are of increasing importance in the transport industry. With this in mind, an Austrian customer developed a unique lightweight semi-trailer using Welser profiles. What makes this trailer special is that it weighs less than 4.7 tons and is characterised not only by high tensile steel properties and innovative material combinations, but also by its modern and visually light appearance. Welser supplies not only the corner posts, but also the outer frame for this innovative semi-trailer. High tensile strength materials and a high level of technical expertise are factors, which provide a decisive competitve edge in the loading industry sector. On the one hand, the reduced weight of the semi-trailer frees up more capacity for the load itself. On the other hand fewer journies and the reduced weight help to protect the environment and human well-being by contributing to a lower fuel comsumption and fewer exhaust emissions.



The semi-trailers undergo intensive quality testing, which involves all of the components undergoing complex calculations and optimisation down to the finest detail before the road testing is carried out. Welser Profile works together its customer to develop and improve materials, to meet the requirements of the transport sector with issues such as the protection of the valuable cargo and road users at the forefront.
