Rollforming Solutions - Innovative Product Simplifies Supply Chain and BOS-costs
Objective: Steel and stainless steels are widely used in PV applications, particularly in the base constructions of large-scale plants. The advantage of these materials is their worldwide availability, the possibilities of large-scale industrial production and their positive material properties. An example is replacing existing hot rolled profiles with special lightweight construction profiles to simplify the mounting of diverse components.
Methods: The optimization of the strip thickness and width, integrated into the cold rollforming process, allows different design and a integration of functions . Innovative methods and also offline simulations were necessary to check the realization for this complex cold rolled profiles.
Results: An cold rolled - beam can reduce expenses in logistics, in the timeline and reduce the burden in the handling on site. A faster, state of the art, manufacturing process eliminates waste and reduces construction lead times. High strength steel and better corrosion protection results in a stronger, longer-lasting, more cost-effective profile, allowing it to meet or exceed difficult site demands.
Conclusion: The high level of quality required by the customer and long functional life required of photovoltaic systems should also be taken into consideration. It is also now possible to manufacture steel profiles with varying wall thickness using a newly developed production technique. The strip is optimised according to the required function of the profile, inline, in a single production process by thinning, thickening or grooving, in order to achieve the desired cross sectional shape. The process requires less material resulting in a weight saving and new or exisiting functions can be integrated.
