Bladt Industries Relies on BUMAX for Offshore Wind Turbine Foundations
Background
Bladt Industries, a leading supplier of large-scale steel structures for the offshore energy sector, was tasked with delivering high-performance foundations for a new offshore wind farm. The project demanded fastening solutions that could withstand extreme conditions — including saltwater exposure, strong winds, and continuous mechanical stress — for a projected 27-year operational lifespan.

Our Features
The Challenge:
In coastal and offshore environments, fasteners are constantly exposed to corrosive elements that compromise structural integrity over time. For this project, Bladt needed a solution that would:
-
Resist long-term corrosion in salt-laden air and direct seawater contact
-
Maintain high tensile strength to ensure structural stability under dynamic loading
-
Deliver maintenance-free performance to minimize lifecycle costs and eliminate offshore service needs
Standard fasteners could not meet these rigorous demands, prompting Bladt to seek a more advanced solution.
The Solution Approach:
Bladt Industries partnered with BUMAX to supply SDX 109 super-duplex stainless steel fasteners — known for their exceptional strength, durability, and corrosion resistance in the most aggressive environments.
Why SDX 109 Was the Perfect Fit:
-
Corrosion Resistance: Crafted from premium super-duplex stainless steel, SDX 109 fasteners are engineered to resist saltwater and atmospheric corrosion, ensuring long-term protection for structural connections.
-
Superior Mechanical Strength: The fasteners provided the high tensile strength required to secure the external platform of the wind turbines under constant mechanical and environmental stress.
-
Maintenance-Free Operation: With SDX 109, Bladt eliminated the need for future replacements or inspections — a major win in reducing operational costs and ensuring uninterrupted turbine performance.
The Results:
BUMAX SDX 109 fasteners delivered exceptional results for Bladt Industries:
✔ 27 years of projected maintenance-free performance — eliminating the need for costly offshore service or replacement over the turbine’s lifecycle
✔ Complete structural reliability — withstanding continuous exposure to saltwater, wind, and mechanical stress without degradation
✔ Significant lifecycle cost savings — fewer maintenance visits, no unplanned downtime, and a lower total cost of ownership
✔ Simplified project planning and installation — with fasteners that met strict performance criteria without the need for additional coatings or post-installation treatments
✔ Enhanced sustainability profile — by extending component lifespan and minimizing material waste over time
✔ Proven trust in critical infrastructure — reinforcing Bladt’s reputation for quality and reliability in offshore energy development
