sustainable fastening materials from European production

Stafa Group supplies high-quality structural fasteners for bridges, sports complexes, industrial halls, and other steel construction projects throughout Europe. The safety and service life of any structure are directly related to the quality of the connections. Bolts, nuts, and threaded rods transfer enormous forces and largely determine the performance of the entire structure. The right choice of materials, production method, and surface treatment are essential to prevent fatigue, corrosion, and loosening.

Sustainable and reliable delivery

More and more projects require products with a demonstrable origin, short supply chains, and stable delivery. That is why Stafa supplies SB bolts in accordance with EN 15048-1 from European manufacturers, made from steel with a recycled content of approximately 92 percent. These European-produced SB bolts are a sustainable alternative to overseas imports and reduce dependence on Asia and geopolitical uncertainties within the global supply chain. The combination of recycled raw materials, reliable availability, and consistent quality makes them a logical choice for sustainable steel construction projects.

German precision and maximum reliability

For applications involving dynamic loads, Stafa Friedberg supplies HV prestressing bolts in accordance with EN 14399-4/6. These bolt sets are manufactured by our German partner August Friedberg GmbH and meet the highest European standards for quality, traceability, and safety. Thanks to this collaboration, Stafa offers access to one of the most respected names in the European fastener industry – a guarantee of consistent performance in bridges, cranes, steel structures, and infrastructure projects.

Knowledge, quality, and logistical certainty

Since 1977, Stafa has been supporting customers in the construction and industrial sectors with a wide range of products and technical advice. The company's strength lies in its ability to contribute ideas right from the design phase. Product specialists advise on strength classes, surface treatments, dimensions, and assembly instructions, ensuring that every connection meets the technical and logistical requirements of the project. In addition to quality, Stafa also offers certainty in execution. With smart inventory programs, assembly, customer-specific packaging, and just-in-time delivery, construction processes become more efficient, failure costs are reduced, and downtime on the construction site is prevented.

Sustainable connections for the future

The future of steel construction is circular, low-maintenance, and reliable. By combining European production with technical expertise, quality control, and sustainable logistics, Stafa strengthens the entire chain. From SB bolts to Friedberg HV prestressing bolts: every product contributes to safe, future-proof, and sustainable connections for European steel construction.
