Aluminium profiles and components – lightweight aluminium solutions for industrial applications

With their huge variety of applications, aluminium extruded profiles are key in machinery and plant construction. The advantages of aluminium profiles are their light weight as well as large range of material properties, combined with countless surface and processing options. Aluminium profiles are the basis for lightweight components that give manufacturers in various industries significant advantages over other materials. Using aluminium is a sustainable option.

Large aluminium profiles for your specific industrial applications

Your aluminium lightweight construction solutions are our priority. You can benefit from our large range of presses and superior quality. Our 100-MN press is Europe’s largest extrusion press and ideal for producing large, complex aluminium profiles. Our central STEP-G location in Bonn has excellent transport connections that enable fast delivery to our customers’ production plants.

Apart from standard sizes, we also produce large profiles with dimensions up to 750 x 50 millimetres. This gives our customers an extra competitive edge because they can produce components without needing further processes to build the profile. 

Custom processing of our aluminium profiles for machine & plant construction

However, at STEP-G our service goes beyond extruded aluminium profiles. We constantly work on improving our products and services both in-house and with external partners. This is how we can offer you a whole range of further processing options: You can choose between machine processing, manual or robot welding as well as various surface finishes of your aluminium profiles. However, complex the supply chain, we act as a central facilitator and experienced partner for our customers.

We deliver the mechanical properties you require

Thanks to our specialist equipment, huge range of alloys and experts who draw on years of experience, we have the flexibly to implement your requirements for customised aluminium profiles. Being in constant dialogue with our customers we explore new ways of replacing established materials such as steel with lightweight alternatives and solutions. Aluminium comes not only with excellent material properties, but also offers effective sustainability.

STEP-G is a producer of sustainable solutions made from extruded aluminium profiles. Thanks to our many years of experience, we are a reliable partner that realises innovative products for our industrial customers.
