FOCUS ON ROLL FORMING
SUSTAINABLE ROLL FORMING
With the ‘ Green Deal ’, the European Commission is obliging industry to become greenhouse gas-neutral by 2050 . However , the gradual reduction in available emission allowances envisaged for this will pose challenges for manufacturing companies in the foreseeable future . To avoid falling into a cost trap , emissions must be reduced as much as possible and the use of CO₂-intensive raw and auxiliary materials must be organised as efficiently as possible .
“ DREISTERN , who celebrated its 75th anniversary in 2024 , is introducing a new system that makes it possible to detect profile straightness on the roll forming machine .”
Sustainable roll forming processes are possible through intelligent scrap avoidance . Planned scrap rates of significantly less than 1 % of the material used are already within the realms of feasibility in roll forming today , DREISTERN told ISMR .

In terms of the carbon footprint of entire industrial sectors , the production and processing of steel has the largest industrial carbon footprint to date ( ahead of cement product production ¹). New ways of producing crude steel , which are being promoted by wellknown major steel manufacturers under the banner of ‘ green steel ’, offer the potential to significantly reduce the CO₂ footprint .
However , a closer look at the material flows within the life cycle of steel reveals another challenge : a good fifth of the steel in circulation is in an endless loop between melting furnace , processing and scrap container and is never used as a final product in this cycle ².
