CONNECT4C: Engineering the future of circular steel construction 

CONNECT4C is a pioneering RFCS research project reshaping how the world builds in steel. By developing next‑generation high‑strength connection systems, it makes genuinely circular steel buildings possible, with elements that can be easily disassembled, reused, and reconfigured rather than demolished, directly supporting EU decarbonization goals and unlocking new economic value through material recovery and adaptive reuse.

The project focuses on practical, market‑ready solutions: standardised three‑dimensional connection systems, including advanced beam‑to‑column nodes, column splices and innovative long‑bolt concepts. Each solution is rigorously validated through experimental testing and numerical analysis, supported by clear design guidance and digital tools that smooth integration into everyday design and construction workflows.

FATOR: Industrial excellence driving market adoption

FATOR brings distinctive value to CONNECT4C through a strategic dual role that connects innovation with market impact. As a leading industrial fastener specialist with a strong track record in steel structures, solar energy and transport infrastructure, FATOR designs and manufactures advanced fastening systems that meet the most demanding performance and reliability requirements worldwide.

What truly differentiates FATOR is its end‑to‑end capability: from early‑stage technical consultation and custom product engineering, through certified manufacturing, to optimised international logistics. This integrated model ensures CONNECT4C’s connection concepts are not only structurally advanced but also manufacturable at scale, cost‑effective and ready for real‑world deployment on site.

As the leader of the project’s communication and dissemination work package, FATOR serves as the key interface between cutting‑edge research and the construction market. By hosting project meetings, engaging directly with industry stakeholders and translating technical advances into clear, actionable solutions, FATOR ensures that CONNECT4C delivers concrete benefits to designers, fabricators, asset owners and the wider built‑environment ecosystem.

The FATOR advantage: Innovation made investable

Through CONNECT4C, FATOR converts breakthrough joint technologies into competitive advantage by aligning them with real industrial constraints, procurement models and project timelines. The result is a portfolio of sustainable, high‑performance connection solutions that are ready to specify, manufacture and install today, turning circular steel construction from vision into a scalable business reality.
